Haplogroup Assignment; Old Habits that Die Hard

Introduction:


It has become a common theme in DNA research papers dealing with population genetics, particularly those that are either published in the "west" or else rely heavily on references to previous publications by "western" research teams, to dichotomize human phylogeny neatly into two main types: African and non-African. As a result, a good amount of the readership of these papers have also become accustomed to treating human phylogeny accordingly. No doubt that the reactionary segment of that readership have applied such a phylogenetic arrangement synonymously with "races" of humanity.

It's one thing to assign human phylogeny into two main types, but it's another, in terms of how these assignments take form. One would be hard-pressed not to come across a single example, whereby lineage that is given an "L" designation in mictochondrial phylogeny, is automatically treated as "African", while the two main offshoots of the L3 clade are taken for granted as "non-African". Such arrangements tacitly or by design, insinuate non-overlapping phylogeny between the so-named two main groups. The discussion section will deal with this kind of arrangement of human phylogeny further, applying specific examples from published material.

What Ethiopian Genetic Diversity—Really—Reveals!

Introduction:

A recent publication by Pagani & co. (2012), under the heading "Ethiopian Genetic Diversity Reveals Linguistic Stratification and Complex Influences on the Ethiopian Gene Pool", revisits the recurring issue of Ethiopian DNA profiles. In fact, one of the participants of this research, Toomas Kivisild in particular, was one of the authors of one of the last major studies on Ethiopian mtDNA, which was also a subject of blog posting on this site [see: Following Trails of the Cro-Magnon - I and Following Trails of the Cro-Magnon - II, for examples]. Some interesting findings surfaced in that study, as it relates to peculiarities about Ethiopian mtDNA gene pool; these same characteristics reappear in this latest study, as well shall notice in following segments of this entry.

As the authors start of their notes with laying out the goals of their research, they point out the supposed shortcomings of previous publications, particulary as it concerns Ethiopian DNA. In doing so, the authors lament on the supposed infrequency of DNA studies—involving African samples—that focus on Ethiopians in contrast to African samples from central and western Africa. This is right after the authors tell the reader that, because Ethiopia has proven to be relatively rich in human paleontological record, and in their words, "because of Ethiopia’s geographical position between Africa and Eurasia, its capital, Addis Ababa, is often used in genetic studies as a proxy embarkation point for modern human range expansions."

This smacks of double speak, when one considers that the subject of "human range expansions" figures quite a lot in population genetics research undertaken by 'western' research teams, and these seldom avoid including eastern Africa, the African Horn in particular, because its often implied rep of being a "cradle" to modern humanity. On top of this, Ethiopians have often served as "props" by Eurocentric ideologues, both in amateur and academic circles, to effect some ideologically-expedient wedge or another between continental Africans, whereby they feel at liberty to isolate what they either presume to be the source of "their kind" (Europeans) from the "others", who are generally lumped together and dismissed as being "inferior" and/or "undesirable", or use the target group—like Ethiopians—to explain away, and importantly, diminish natural African diversity as that made possible primarily because of foreign contribution.

Genetic Profile: Maghrebi populations are Not "Satellite-Europeans" in Africa

Introduction: 

Many observers will note that at some point in time or another, they witnessed (if not perpetrators themselves) internet inquiries around the origins of Maghrebi populations, whom as indigenous Africans (let's face it; they are not endemic to any other region outside of Africa), are notable not only for having elements among them who are relative "outliers" in terms of epidermal pigmentation, but also for their own original distinctive language family, properly called Tamazight—otherwise inconsiderately known in English lingo as "Berber". These populations have wittingly or unwittingly been subjects of racism, in the sense that their "African-ness" have been questioned primarily because of appearance of those populations among them with "light skin", "depigmented skin" or "white skin'—the terms change depending on who's speaking. If for example, they were unanimously dark-skinned like the remainder of African populations, it is highly doubtful that "western" researchers would even consider tacitly passing them off as some sort of lost-Europeans (or extensions of Europeans) in Africa, notwithstanding any genetic similarity to the patterns seen today of Maghrebi populations.

How are the Media and Schools catching up with Scientific Progress? Pt.5

Introduction:

We proceed on from the last segment, wherein we looked at how nationalism and like ideology continues to plague science. No science has infamously suffered from this more than the discipline of human palaeontology. In the "west", the venture into this field started with getting to know remains of the European Neanderthal, and the sparking thereof, the belief that Europe was the hub of human origins.

How are the Media and Schools catching up with Scientific Progress? Pt.4

Introduction:

In the previous segment, a good deal of space was dedicated to a straightforward preliminary look at the portrayal of non-European peoples, especially Africans, in "western" media not merely as a loosely connected hodgepodge of unconscious and conscious underlying motives, ranging from economic considerations to racism, but rather, as a conscious undertaking of "western" imperialism, of which the 'western' establishments are quite mindful.

How are the Media and Schools catching up with Scientific Progress? Pt.3

Introduction:

In the previous segments of the this blog entry, much attention was paid to History channel documentary reenactments of the ancients of Africa, particularly the Ancient Egyptians. Ancient Egypt has been the most popular subject of 'western' fascination and romanticism, but this sort of thing has not been limited to just Egypt. It has been extended to other African complexes, from Timbuktu, the Great Zimbabwe, to ancient Abyssinia (modern day Ethiopia). A good example of this can be seen in the portrayal of an Ancient Abyssinian kingdom in the now 9 year old comedy flick of the title "The Hot Chick".

How are the Media and Schools catching up with Scientific Progress?-Pt2

Carried on from the first entry.

Introduction recap:

The taking up of African historiography by Europeans has long been mired with disinformation, as scholars of European descent sought to accommodate imperialist designs of their governments around the African continent. This matter had been particularly brushed on briefly in an earlier entry discussing the significance of additional Timbuktu chronicles that were brought to light in recent times and the corresponding rush to preserve those relics, whereby we come across the systematic construction of the "Ghana Conquest Theory", at a time when European polities had their eye set on colonizing African territories and fuel their growth with African resources. The historiography of Ancient Ghana, and Western Sudan (otherwise now recognized as "West Africa") in general, was but just one element of this disinformation campaign; the policy had extended to other elements of African historiography, Ancient Egypt being the most popular and enduring example of this. Complexes from Kush, Abyssinia or Aksum to the Great Zimbabwe had all become casualties of European disinformation.

KhoiSan: As the "Oldest" Surviving "Tribes"


The reader may recall having heard the claim that the KhoiSan are the "oldest living human populations" at some point or another. The saying may well have taken the character of something of a religious faith within some circles. When the whereabouts of the source for this "understanding" is inquired, common references have been to the National Geographic human genome project web-page and Semino et al.'s (2001) study regarding the "deepest clades" for instance. The former bases this on rather flimsy material that KhoiSan male gene pools comprises of deep root clades like hg A, while the latter has every now and then fallen victim to misunderstanding or misinterpretation of what is being related in the authors' findings within the contexts that they were made. Fact is the KhoiSan are no more representative of the oldest anatomical modern human beings any more than other living populations.

An Interesting Encounter...

Several months back, in a forum discussion, the present author came across something quite interesting on the website of the owner of the said forum—going by the name of F. W. Sweet, and this is what it says/said:

"It seems that Dr. Shriver’s maternal grandfather moved from Pennsylvania to Iowa, then to California, leaving behind in the process most of his ties with his relatives.23 Dr. Shriver, it turns out, (see photograph above) is one of the 74 million White Americans with significant recent African genetic admixture.

In a coincidentally similar fashion, Dr. Rick Kittles, Shriver’s collaborator from Howard University in Washington, discovered that he carries the FY-null genetic marker at genome position 16q24.3. This marker is found in 998 out of every thousand Europeans but found in only one out of thousand Africans. Many of Dr. Kittles’s other ancestry-informative markers tell the same unexpected story. Dr. Kittles (see photograph above) is one of the many Black Americans with strong European genetic admixture. And yet, and there is no other way to say this, Dr. Shriver “looks White” and Dr. Kittles definitely “looks Black.” Why is there such a discrepancy between measured genetic admixture and physical appearance?" - by F. W. Sweet

At the time, this is what the present author posted in response to the extract:

Yes, I’ve seen both Dr. Shriver’s and Dr. Kittle's appearance, and I must say, it is hard to believe that either have low European or African recent ancestry respectively. If indeed the labeled sample belonged to either party, assuming that the said alternative coincidences did not arise from any probable technicality in the labeling, then I can only come to the conclusion that, the DNA sites examined as such, were made possible because those sites were kept intact in either one of their immediate parents, and if Shriver’s mum’s reaction is any indicator to go by, upon hearing the news, these markers would have been kept intact in her “white-appearing” father. Speaking of father, according to Mr. Shriver, how did he reach the conclusion that it had to be from his mother’s dad’s side, and not necessarily from his mother’s maternal side? Also, could it not have come from his father's side, and if not, why? Were many of the said ‘markers’ deemed to have been sex-biased in their genetic transmission?

I had the result for two or three years before I even looked up the ID number of the person whom we tested. I looked at who it was and it was me! I checked myself and the rest of my relatives and tracked it through my family. I never considered that there were any African people in my family. There’s no real variation in my family. The admixture must have been pretty far back. It just so happens that we can detect it with the markers we have. My mom especially stood out as being surprised, maybe because I told her it was coming through her father. She still doesn’t believe it about her family! The part of Pennsylvania where my mother’s father came from is where the Underground Railroad ended. There are several towns right here in Southern Pennsylvania where there are very light-skinned African-American communities that are the remnants of the Underground Railroad. - by Shriver

So, not only would those markers have to be deemed “invisible” in terms of their impression on phenotype, but they would have had to remain intact to account for their genetic integrity throughout the parent-to-offspring transmissions for at least a few generations. For Dr. Kittles to retain that level of melanin, it occurs to me that he’d had to have been a product of a union between parents from families that had maintained endogamy for at least a few recent generations, likely of families that have had long enough tradition of socially identifying with the “black“ or “colored” community. I suspect, since I cannot say for certain without independent corroboration, that either of these two researchers would likely indirectly clue us in on this possibility through either paternal and/or maternal DNA markers, which by normal account, correspond to Y-chromosome markers and mtDNA respectively. Either that, or else more “AIM” would have been needed to be identified to account, if not *indirectly*, for the genetic component counterparts of their ancestors who were responsible for transmission of their phenotypic appearance - as is the case with skin color and hair texture for example. I realize these traits have their own markers, but I'm referring to the broader hereditary component of the parties who were primarily responsible for transmitting those traits. It is hard to imagine that only those 'visible' markers of those ancestors withstood the test of time, while every other component of their genetic transmission was swamped through the generations, particularly for 'immediate' family households who would swear that the maternal and paternal lines of the said family come predominantly from one ethnic endogamous group [be it "white" or "black"].


With regards to piece about Kittle’s ancestry, this was said:

In a coincidentally similar fashion, Dr. Rick Kittles, Shriver’s collaborator from Howard University in Washington, discovered that he carries the FY-null genetic marker at genome position 16q24.3. This marker is found in 998 out of every thousand Europeans but found in only one out of thousand Africans. - by F.W. Sweet

But in the tables provided, this location should have been associated with MC1R-314*, and not the FY-null marker, which is supposed to have been located at 1q23.2. Was this a typo, or something else is at work here?

And indeed, that was a typo, as the author himself admitted, upon my issuing of the notification above. If indeed the typo was in wrongly naming the loci, which it appears it is/was, then MC1R-314*'s — an allele known to prevalent in folks of recent African ancestry — location in Mr. Kittles' sample should come as no surprise.

Short of some extraordinarily rare situation of these two geneticists — aka Shriver and Kittles — being products of union between a) a parent heterozygous at certain loci linked to outward phenotype traits like skin color, eye color, hair thickness et al., which are generally observed predominantly in one geography than another or in one ethnic group than another, and a parent largely homozygous across said loci, b)OR else, between parents who happen to both be heterozygous at some or the other section of said loci, wherein the offspring [in this case, either Shriver or Kittles] somehow wound up being largely homozygous across said loci, from the look of things, there are very strong indications here that what Shriver was actually looking at as his own, might well have been Rick Kittles' DNA sample, and likewise, Shriver's DNA sample was mistaken for Kittles'. There might have been a technicality at the lab [could be labeling mishap for example, though some other yet-to-be-determined factor(s) could have been the cause] , which somehow escaped both Shriver's and Kittles' attention, and so, they took it for granted, no matter how awkward the results turned out to be, as their own, respectively. This would explain the seemingly reverse results for each candidate, who coincidentally, were partners on research work. Short of specific independent corroboration, obviously this amounts to conjecture on my end; let's just say that I'm throwing out there, a possible scenario for what could have accounted for the results we are told about, aside from considering one of those rare genealogical situations. One thing most of us would agree on, is that those results are certainly interesting!

Comments on the Photo-protective qualities of epidermal Melanin Content of skin

Based on extracts from Yamaguchi et al. 2006, we have the following:

— DNA damage in the upper epidermis immediately after UV exposure was similar among racial/ethnic groups but levels of DNA damage in the lower concentration of the epidermis was inversely proportional to the melanin content.

Courtesy of Yamaguchi et al. 2006: Figure 1. A) Representative images of CPD DNA damage in fair, intermediate and dark skin immediately and 7 d after UV exposure; green and red fluorescence represent CPD and DNA, respectively. (———) demarks the top of the granular layer of the epidermis, (- - - -) demarks the epidermal:dermal junction, and (· · · · ·) represents the division between the upper and lower epidermal layers. B) Representative images of CPD (green) in melanocytes (stained red for tyrosinase) immediately after UV in fair, intermediate and dark skin.

— Pulse lasers cause highly selective injury to cells containing melanosomes suggesting that the UV energy absorbed by melanin in the upper epidermis causes photothermolysis (heat damage) to pigmented cells.

— The oncogene p53 plays important roles in responses to UV-induced DNA damage and induction of DNA repair. There is an overall nuclear accumulation of p53 in response to UV. More than 13 sites of p53 are known to be phosphorylated, one of them being a critical site at Ser-46, which is associated with the induction of apoptosis.

More p53 accumulated in the nuclei of cells in fair skin than in dark skin at 1 d and at 7 d after UV exposure. However, phosphorylation of p53 at Ser-46 was not seen in fair skin, whereas it was readily seen in dark skin 1 d after UV exposure…

Phosphorylation of p53 at Ser-46, which is associated with the induction of apoptosis, occurred at low levels in fair skin after low doses of UV exposure but was significant in dark skin, suggesting that p53 phosphorylation site is involved in UV-induced apoptosis in epidermis with abundant levels of melanin.

TUNEL assays showed that significantly more apoptotic cells were found in Black skin equivalents than in Asian or White skin equivalents at both UV doses...

— nuclear accumulation of p53 is less in dark skin than in fair skin, suggesting that the overall activation of p53 following UV-induced DNA damage is greater in fair skin. The sustained activation of p53 may also in part cause the higher incidence of photo carcinogenesis in fair skin.

— melanin content is responsible for the apoptosis. Cells containing melanin in the upper epidermis of dark skin tended to undergo more apoptosis after UV than do those of fair skin. Thus, the presence of melanin facilitates the apoptotic effect of UV on cells but whether that results from photothermolysis or whether other properties of melanins are involved will require further study.

DNA damage in the upper epidermis immediately after UV exposure was similar among racial/ethnic groups but levels of DNA damage in the lower concentration of the epidermis was inversely proportional to the melanin content.
Taken together,…

— UV-induced DNA damage in the lower epidermis (which contains keratinocyte stem cells and melanocytes) is not effectively prevented in fair skin because of the low melanin content in the upper (and lower) epidermis.

— DNA damage in the upper epidermis is quite similar among all types of skin, which indicates that epidermal pigmentation is an efficient UV filter for underlying cells.

— UV-induced apoptosis was virtually absent in fair skin after low UV doses, but was significant in dark skin, facilitating the effective removal of UV-damaged cells in dark skin.

— Virtually all epidermal cells had significant DNA damage in fair skin but only ~1% of them became apoptotic whereas less than 50% of epidermal cells in dark skin had significant DNA damage, yet ~ 5% of those cells were apoptotic.

— The combination of relatively low DNA damage and efficient removal of UV-damaged cells contributes to the decreased incidence of skin cancer in darker skin.

we conclude that the upper epidermis of dark skin is significantly more photoprotective for the deeper tissue against UV damage than that of fair skin.

And now, on the understanding gleaned from the above, some personal observations about the photo-protective qualities of epidermal melanin content:

Essentially, the side effect of UV-radiation damage of DNA in epidermal cells is the activation of the p53 gene to presumably suppress cell division of damaged DNA, and allow for repair, which would explain the accumulation of this type in cell nuclei after UV exposure. However, given the greater DNA damage in fair skin due to reduced melanin content, more p53 are activated than the case is for dark skin; the other problem here though, seems to be that there is also a strong correlation between the phosphorylation of p53 at the Ser-46 locus of the gene, which appears to be critical for apoptosis, and epidermal melanin content; the greater the epidermal melanin, the greater chances of greater occurrence of nuclear p53 genes phosphorylated at their Ser-46 locus. The precise triggering aspect of melanin on apoptosis is something that is subject to further investigation, according to Yamaguchi et al.: the presence of melanin facilitates the apoptotic effect of UV on cells but whether that results from photothermolysis or whether other properties of melanins are involved will require further study.

Since this development [phosphorylation] at the Ser-46 locus appears to be much rarer on p53 genes in epidermal cells of fair skin, the prospect of apoptosis occurring after UV exposure is substantially lower, if not rare. This means that damaged DNA are allowed to spread via cell division and so, defects being passed onto daughter cells; on the other hand, greater presence of phosphorylation of the p53 gene at its Ser-46 locus in dark skin epidermal cells allows for effective removal of UV-induced damaged DNA. So, it would appear that the hindrance of p53 gene in fair skin epidermal cells to play a role in removal of cells containing damaged DNA in the process of assisting in DNA repair, at least in part, interrupts the optimal balance between cell division and apoptosis, thereby contributing to photo-carcinogenesis. [see: Yamaguchi et al. 2006; Human skin responses to UV radiation: Pigment in the upper epidermis protects against DNA damage in the lower epidermis and facilitates apoptosis]

How the term "Berber" stuck to modern day Amazighan speakers

Regardless of the ultimate origins of the term "Berber", it seems pretty clear that the term became particularly synonymous with contemporary Imazighen speakers from the Medieval era onwards, specifically during "Moorish" rule in Europe. And of course today, within the scholarly world of the so-called 'West', the application of this term is justified on the condition that it is strictly a linguistic construct for a Afrasan (Afro-Asiatic) subphylum of certain closely related languages. The term itself is never applied by Imazighen groups to refer to themselves, and so, in that sense, foreign to them. Imazighen groups generally refer to themselves as '- mazigh' in one dialect variant or another. There are several theories out there, as to how the term came to particularly designate Imazighen groups, as opposed to random groups of "strange" or "foreign" people, but the most plausible of these, is the Arab/Moorish connection in Europe. Let's examine...

To the ancient Greeks, the idea of strangers or foreigners wasn't limited to just northwest Africans; rather, it also covered 'strange' people in their own European backyard. Europeans to their north were generally seen as strange, if not uncultured, from the ancient Greek standpoint; their cultural manners were seen as peculiar and foreign to ancient Greeks, and so, they were referred to as 'barbary' (barbarians). Certainly, this term was applied to elements of northeast African populations in the Nile Valley as well; consider this piece on Achilles Tatius' thoughts for instance, with regards to late dynastic delta ancient Egyptians:

"All were huge, black-skinned [not the pure black of the Indians , more as you would imagine a half-caste Ethiopian], bare-headed, light of foot but broad of body. They were all speaking a barbarian language. " - Extracts presumably from Achilles Tatius: Leucippe and Clitophon

Tim Whitmarsh who translated the work and Helen Morales who gave a synopsis of the work, characterize the above description as a reference to some Nile Valley elements who were apparently seen as a nuisance to Greek interest, because we are told that the folks who were so-described [aka the "boukoli" bandits of the coastal areas of the Nile Valley], where one of those groups who were singled out by this sort of characterization, which amounts to an image of "unculturedness"; whereas...

All of the characters, weather they are natives of Phoenicia, Byzantium, Egypt, or Ephesus, speak in Greek, have Greek names, and demonstrate Greek paideis or culture. The exceptions are the boukoli, the bandits who ambush Leucippe and Clitophon. They are described as ''terrifying savages". - by Helen Morales (Introduction) and Tim Whitmarsh (Translator)

But Morales and Whitmarsh warn of any premature conclusions to be drawn from this "Greekifying" of things not actually Greek:

But to read Achille's description as a reflection of reality is grossly to underplay his rhetoric of demonization. The boukoli are caricatures , like other ethnocentric stereotypes of Egyptians elsewhere in the novel [eg at 4.4: ''Thus it is with an Egypt: in times of fear cowardice leads him to servility''] Geographic and description ethnographicreinforce this construction of the alterity of Egypt...

The description of the Egyptian clod of earth emphasizes its different and strangeness [3.13, and cf. the description of the Nile's duplicity at 4.12].

Despite Achillies' being a native of Alexandria, he perpetuates the ethnocentric stereotypes of Egypt familiar from many centuries' construction of Greek self-definition against the 'Barbarian'. - by Helen Morales (Introduction) and Tim Whitmarsh (Translator)

What does this say of the Greeks? The last bit about "Greek self-definition against the Barbarian" goes back to what the above authors reckon to be Greek arrogance of "reaffirmation of Hellenic superiority"; it serves to explain why the aforementioned point about "Greekifying" things not Greek where convenient or the opportunity to do so, was done so; to recap: All of the characters, weather they are natives of Phoenicia, Byzantium, Egypt, or Ephesus, speak in Greek, have Greek names, and demonstrate Greek paideis or culture. The exceptions are the boukoli, the bandits who ambush Leucippe and Clitophon. They are described as ''terrifying savages". - by Helen Morales (Introduction) and Tim Whitmarsh (Translator)

Perhaps might explain why Egyptian names were given Greek alternatives, like say Ausar for example, which is given the Greek alternative of "Osiris"; it might well tie into that theme of "reaffirmation of Hellenic superiority". All things great, even if not Greek, but has been brought into sphere of Greek interest, would have to be "Greekified" in some way or another. At any rate, the point here, was to show lack of restrictiveness to Greek application of "barbarian" to anyone or anything that was out of the norm from the Greek standpoint; it certainly wasn't restricted to coastal northwest African regions, and so, the idea of ancient Greeks being the source of this designation vis-a-vis northwest African Imazighen groups by sections of European scholars from the Medieval era onwards is a questionable one. The Roman application of such a term faired no differently.

Some sources suggest that the earliest north European examples of exclusive reference of "Berber" — that is, in that form as we know it, which is not exactly "Barbarian" as the Greek word itself, occur in French texts. The French word itself for anything strange or foreign is "étranger", and "babarian" — "barbare". Incidentally, Arabs in the Medieval era, during their endeavors in north Africa, exclusively called coastal northwest Africa, as opposed to the whole of coastal north Africa, as Bilad al Barbar ~ essentially meaning: Land of the Barbar/”Berber”. Could the Arab term have ultimately been attained from Indo-European infusion? Perhaps possible, but unless brought to immediate attention, no other north African region, save for the northwest region — which was also designated as Maghreb al Aksa by Arabs from the so-called Near East — has been so-designated as "Bilad al Barbar". Coincidentally, this is also the same region from where Arab and Moorish rule in southwest Europe would be launched. It would therefore seem that exclusivity of application of this with respect to Imazighen speakers by Europeans has its roots in Moorish-controlled southwest Europe, from wherein the alternative generic Arab geographical designation for the Maghreb diffused into European vocabulary. So, the term initially used as a generic geopolitical reference to people in coastal northwest Africa, the Africans then — in the Medieval era — best known to Europeans and were in relatively more regular contact with them, would evolve into a linguistic reference, which would tie coastal northwest Africans with other groups who spoke closely related languages.

As far as primary text attestations are concerned, Arabic-sources have been reliable; for example Ibn Khaldun, likely an Arabized Amazighan writer in Moorish-ruled southwest European era, born in Tunisia, wrote an auto-biography Ta’reef in Egypt, as part of his work in what he calls, Kitab al-’Ibar wa-Diwan al-Mubtada’ wa-l-Khabar fi Ayyam al-’Arab wal-’Ajam wal-Barbar wa man ‘asarahum min dhawi as-Sultan al-Akbar [courtesy of cis-ca.org]

We now revisit several interesting explanations of how the term "Berber" as a generic reference to Amazighan speakers came about...

From a "Non-Governmental Organization For the defense of the rights of the Amazigh" called ‘Tamazigha’, we are told:

North Africa, an Amazigh land


All the historians of North Africa attest that the country has been populated by the Amazighs (Berbers) since very ancient times. Ibn Khaldoun in his Histoire des Berbères, wrote concerning the country which is usually referred to as the Maghreb and which we call Tamazgha or country of Imazighen (= plural of Amazigh):

«Since ancient times, this race inhabited the Maghreb of which it populated plains, mountains, shores, cities and countryside (Ibn Khaldoun, Histoire des Berbères, Paris, Geuthner, 1999, p. 167).»

And relating to Tamazight, the language of the Amazighs:

«Their language is a foreign idiom, different from all idioms: the very reason the name Berber was given to them (Ibn Khaldoun, 1999, opus quoted p.168). »

Finally regarding the religions practiced in North Africa:

«Among them there were [tribes] which practiced the Jewish religion; others practiced the Christian one, and others pagan ones, and among the latter were sun, moon and idol worshipers. Having at their head kings and leaders, they carried out against the Muslims several very famous wars (Ibn Khaldoun, 1999, opus quoted, p. 177).»

Closer to us, in 1931, the anti-colonialist historian Charles-André Julien observed that:

«Today, it is generally unknown to the majority that Morocco, Algeria and Tunisia are populated by Berbers. These are boldly referred to as Arabs, all the while the natives often called themselves Amazigh (Tamazight for the feminine and Imazighen for the plural) which literally means "free people", or sometimes "noble people" and was used by several tribes as far back as before the Roman occupation. (C.-A. Julien, Histoire de l'Afrique du Nord, Paris, Payot, 1931, p. 2).»

Source: ‘Tamazigha’, A Non Governmental Organization For the defense of the rights of the Amazigh, in submission to the ‘Committee for the Elimination of Racial Discrimination (CERD)’ in 2003.

Explanation given in a Kabyle dedicated site by an author going by the name of D. Messaoudi:

For some people, the origin of the word “Berber” would be Greek; their argument rely on the fact that the Greeks called people who spoke a language other than Greek “the Barbarians”. For the Arabs, the above word would be borrowed from Arabic, since in this language there is the verb “Barbara” (to roar) and “Al-barbarah” (“roar” and by extension, incomprehensible language – the equivalent of “baragouin”, meaning gibberish, the name given to the Breton language by the French).

But, in my view, these hypotheses rely on no logic, because in that period, the Berbers were not the only ones with whom the Romans or the Arabs had contacts. Why therefore other people as the Copts, the Kurds, the Sudanese, the Iranians, the Basques, etc, who spoke languages completely different from Latin and Arabic, had not been called “barbarians / Berbers”?

This incites us to search the origin of the above-mentioned appellation elsewhere, and more precisely in Berber language itself.

Our research in different Amazigh dialects led to the discovery of a group of terms and expressions with which we can associate the term “Berber”:

* Iber-iber: nomad in Touareg

* Sberber: be covered with clouds, when speaking about the sky in Kabyle, or to protect somebody or something by covering it with one’s body.

* Sbur: to cover one’s head in Kabyle

* Ibeṛbaṛen: a village located in Mcheddala, Bouira

* Tizi-n-Beṛbeṛ: another village in Kabylia.

* bbeṛbeṛ: very wet, in Kabyle.

My first assumption is that the term “Berber” would be a distortion or perhaps an evolved form of the word attested in Touareg, i.e. “Iberiber”. We know that the Berbers were called “Imazighen”, but maybe the appellation “iberiber”, which became then “Berber”, indicated only a particular grouping of Berbers, as the Touareg which were always big nomads. It would be then the Northern Berbers that would have created this nickname to indicate the Saharan, and the foreigners generalized it then to all Berbers.

My second assumption is that the term “Berber” would have a lexical relation with the words “sbur” and “Sberber”, which are both created on the basis of the same root: “BR”. In fact, if we refer to the dress habits of the North Africans, we will realize that the Berbers, since immemorial time, prefer broad clothings which cover them completely: Kabyle abernus, Shleuh tajellabit, Targui tagelmust, etc., are some examples. Even the Berber women wear long tiqendiar and timhermin or else asburru to protect their heads. It would be therefore the reason for which the Berbers were called, besides Imazighen, “Iberbaren”, which became then “Berber” in foreign languages.

Last but not least, explanation given by Richard L. Smith of the Ferrum College:

Moving beyond race, language—one of the defining characteristics in the modern concept of ethnicity—is rarely mentioned by classical or Arab authors except to note that their subjects spoke some form of gibberish. This began with Herodotus's offhand remark about the Ethiopian troglodytes: "The language they speak is completely different from any other language, and sounds like bats squeaking,"43 and continues through the sixth-century poet Corippus, who, in referring to Berber tribes, notes that their "barbaric languages bark in savage terms."44 Authors don't usually distinguish gibberishes from each other, nor do they state categorically that language was a major criterion for dividing the peoples of North Africa. Perhaps, however, we should assume this. Tacitus, who falls into the Sallust school in his discussion of North Africa but whose study of the German tribes is unsurpassed in classical ethnography, does refer to the importance of language in his review of peoples to the north of the Roman Empire.45 In other regions of Africa, including nearby West Africa, language has often served as an insignia of ethnicity.

Ibn Khaldun does distinguish the Berbers from the Arabs and other peoples by their language. According to him, the Arabs gave the Berbers their name, the origin of which meant something like gibberish: "The word berbera signifies, in Arabic, a jumble of unintelligible cries; from which one says in speaking of the lion that it berbère when it utters confused roars."46 *


[46 * - “ Histoire I:168. In another place, Ibn Khaldun offers an alternate if similar explanation. According to this, a Yemenite king named Afriqus b. Qays b. Sayfi, who lived at the time of Moses, often raided North Africa and killed many Berbers: "He gave them the name of Berbers when he heard their jargon and asked what that barbarah was." Ibn Khaldun, The Muqaddimah: An Introduction to History, trans. Franz Rosenthal, ed. N. J. Dawood (Princeton: Princeton University Press, 1967), p. 14.” - Richard L. Smith]

Richard goes onto say:

The unintelligible cries were the many local dialects Berber was divided into, by one modern count an astounding twelve hundred, although the situation at the time of Ibn Khaldun can only be guessed. And while Berber languages show relatively little internal differentiation in comparison to other branches of the Afro-Asiatic family, a detailed language map of Berber speakers would have the pattern of spilled vegetable soup.47* [47* - “For a background on the origin of Berber and its derivatives, see P. Behrens, "Wanderungsbewegungen und Sprache der früken saharanischen Viehzuchter," Sprache und Geschichte in Afrika 6 (1984–85): 135–216.” - Richard Smith]

In the past scholars have tried to get a handle on this so-called "language of dialects" by recognizing two or three dialect clusters—Zanatiya, Sanhaja, and sometimes Masmuda (which, when not recognized as separate, is joined with Sanhaja)—based on phonetic and morphological variations and location. Zanata, Sanhaja, and Masmuda are not terms used in the writings of the ancients but do appear, full-blown, with Arab authors who draw a clear distinction between them. The Masmuda were concentrated in the High Atlas and surrounding areas while in the rest of North Africa the Zanata (those who speak Zanatiya) were more common in the north and east and the Sanhaja in the south and west. The word "Sanhaja" means those who speak Zenaga (Znaga), the major dialect of the western desert. - Richard L. Smith

Then there are legends of ‘Berber’ ancestry, one of which as already very briefly mentioned, is traced back to a personality(s) by the name of “Berr”:

According to the Arabian genealogies, all Berbers are descended from two men: Berr ibn Branes and Berr ibn Botr.79 These two Berrs, although possessing the same name, were not related. From them are descended the great families of Berbers such as the Masmuda, Senhaja, and Zenata. Of all these great families the earliest to spread seems to have been the Masmuda or Ghomara branch. This was followed traditionally by the Senhaja, who today include such varied peoples as the Siwans on the borderlands of Egypt, the Tuareg of the Sahara, and the Braber of the Middle Atlas in Morocco. The third great expansion was that of the Zenata, who were known in Roman times in Cyrenaica, but who did not reach Algeria and Morocco until the Middle Ages. In the thirteenth century these Zenata finally invaded Spain, conquering Arabs and earlier Berbers. One may compare the expansions of the Berber families to those of Kelts, Germans, Slavs, etc. in Europe. - Courtesy of snpa.nordish.net

From the above, the present author can only imagine that the website is basing this on Arabic-speaking others cited in their reference, such as el Bekri and Ibn Khaldun

[More on these sort of legends, from Richard L Smiths analysis:

Unlike Herodotus, Ibn Abi Zar did recognize that his subjects lived in segmented societies,55 but the framework that he and other Arab writers imposed was genealogical rather than anthropological. Groups were defined as descendants of specific people, so exactly who the Berbers issued from was a much debated topic. The most popular starting place was the Holy Land, and first among the candidates was Goliath. After David killed Goliath, the Philistines, frequently confused with the Canaanites, were said to have left their homeland and migrated to North Africa, where they became the Berbers. Not everyone who wanted to keep the Berbers in the Old Testament was convinced of the Goliath connection. One of the most popular accounts goes back to Noah's children, Ham and Sem, among whom Satan was said to have sowed discord:

"Ham, having become black because of a curse pronounced against him by his father, fled to the Maghrib to hide in shame.... Berber, son of Kesloudjim [Casluhim], one of his descendants, left numerous posterity in the Maghrib."56* [56* - “Ibn Khaldun, [I]Histoire
I, 177–178. The Ham connection appears in al-Ya'qubi, Corpus, p. 21. The Goliath connection comes a little later in Ibn Hawqal, Corpus, p. 48. Much earlier, in the first century C.E., the Jewish historian Flavius Josephus claimed that the Gaetulians descended from Havilah, the son of Cush, grandson of Ham.” - Richard L. Smith]

Understandably, many of the Berbers did not want their family trees rooted in Goliath, Ham, or other Biblical ne'er-do-wells. Muslims all over the Islamic world often tried to establish ancestral connections with the Prophet's homeland, the Arabian peninsula, and the Berbers were no exception. A popular theory among them was that they were long-lost Yemenites.

Ibn Khaldun chronicled all the stories he could find concerning Berber origins and demolished each in turn. He characterized one story that featured an invasion by an ancient Yemenite king as an "example of silly statements by historians.
"57* [57* - “Ibn Khaldun, Muqaddimah, p. 14.” - Richard L. Smith] Nor did he mince words concerning another popular theory:

"The opinion which represents them as the children of Goliath or Amalecites, and which has them emigrate from Syria, willy-nilly, is so untenable that it merits classification as a fable."

But Ibn Khaldun proved more effective as a critic than in offering a viable alternative. In the end he, too, traced the Berbers back to Genesis:

"Now the real fact, the fact which dispenses with all hypothesis, is this: the Berbers are the children of Canaan, the son of Ham, son of Noah." Down this line came Berr who had two sons, Baranis and Madghis al-Abtar. All Berber tribes descended from one or the other of these brothers and were classified as either Baranes or Botr.
58* [58* - “Histoire I, 173–185. Also see R. W. Bulliet, "Botr et Beranes: Hypotheses sur l'histoire des Berbes," Annales Economies, Sociétés, Civilisations 36 (1981): 104–116.” - Richard L. Smith]

Continuing…

The Sanhaja were Baranes, and the Zanata were Botr. Further up the tree on the Baranes side were the Mulaththamun, who, according to al-Idrisi, descended from two eponyms, Sanhaj and Lamt. They lived in the Maghrib and were the sons of a mother named Tazakkat (Tizki), "the Lame." But Sanhaj and Lamt produced troublesome broods who tried to conquer the other Berbers and were finally driven into the desert, where they became nomads living in tents and surviving on the milk and meat of camels.59* [59* - “Corpus, p. 127.” - Richard L. Smith]

Arab-imposed, male-centered genealogy tells us more about contemporary Arab historiography than it does about Berber ethnography. This is not to dismiss the importance of perceived descent, which was matrilineal among most Berbers, particularly those of the desert. Etymological analysis seems to indicate that this tradition had its roots deep in the past: the words for brother and sister in proto-Berber, for example, are "son of my mother" and "daughter of my mother" respectively.60* [60* - “G. Marcy, "Les survivances juridiques de la parenté maternelle dans la coutume du Maroc Central," Actes du Congrès del'institut des Hautes Études Marocaines (Rabat, 1937), p. 33.” - Richard L. Smith]

The progenitor of Sanhaja and Tuareg alike was more often than not thought to be a woman, **Tin Hinan** of the Kel Ahaggar being the most well known. Whatever the real story behind the formation of a group like the Lamtuna, a large measure of their self-identity came from the commonly held belief that their eponymous ancestor was a woman named **Lamtuna**, and thus they were related "by blood" to each other.

More on legends, as cited by Richard:

One final aspect of Biblical-based genealogical history is worth noting: it did not start with the Arabs. About halfway through his work, Procopius suddenly announces that it is necessary to tell how the Maures came to Libya. He begins with Joshua and the Hebrews invading Palestine and thrashing everyone in sight. Several of the Canaanite tribes escaped by moving into Egypt, but finding it already crowded, continued on to Libya. Autochthonous people Procopius calls the "Children of the Soil" already lived there; Procopius does not say whether the Canaanites and the Children of the Soil fought or intermarried, only that the Canaanites became Maures.61* [67* - “.V. IV.10.12–24.” - Richard L. Smith] Procopius did not invent the tie between the peoples of North Africa and the Old Testament: for the Christians it goes back to St. Hippolyte in the early third century, but its origins can be seen even earlier in Flavius Josephus and Jewish tradition.62*[62* - “Yves Modéran, "Mythe et histoire aux derniers temps de l'Afrique antique: À propos d'un texte d'Ibn Khaldun," Review Historique CCCIII 2 (Avril–Juin 2001): 327–337.” - Richard Smith] However, Procopius's story does establish a link between portals two and three. It is one of the few strands of continuity, even though it concerns a perceived rather than a real relationship, which brings us back to our original problem: Why does there appear to be such a level of discontinuity?

Richard adds…

The almost complete break in nomenclature between the classical and Arab periods has to raise a few eyebrows. The names we use today come from the sources available to us. Some names originated with the people themselves, as in the case of the Mauri, at least according to Strabo.63* [63* - “Geography XVII.3.2. Later the transliteration became "Moors."“ - Richard L. Smith] Others came from neighbors, and some that ended up in Greek and Roman references were simply botched transliterations.64* [64* - “In the opening paragraph of his discussion on Libya, Pliny complains, "The names of its peoples and towns are absolutely unpronounceable except by the natives," N.H. V.1. See Gustave Mercier, "La langue libyenne et la toponymie antique de l'Afrique du Nord," Journal Asiatique 105 (1924): 189–320.” - Richard L. Smith] Authors confused names probably more often than we suspect. In his tour of the middle of the desert, Pliny notes that "the Blemmyae are reported to have no heads, their mouth and eyes being attached to their chests."65* [65* - “N.H. V.8.46.” - Richard L. Smith] Strabo and others describe a real people they referred to as the Blemmyae, who were nomads living below Egypt. Pliny's Blemmyae, minus the name, were borrowed from Herodotus's discussion of western Libya beyond the cultivated area: "There are enormous snakes there ... donkeys with horns, dog-headed creatures, headless creatures with eyes in their chests (at least, that is what the Libyans say), wild men and wild women...."66* [66* - }Geography VIII.7; 135; Histories IV.191.” - Richard L. Smith] Still others were made up by the Greeks and Romans. Diodorus Siculus provides some egregious examples in his tour of peoples living south of Egypt, which includes the Ichthyophagi (fish eaters), Chelonophagi (turtle eaters), Rhizophagi (root eaters), Hylophagi (wood eaters), Spermatophagi (seed eaters), Stnithophagi (bird eaters), and Acnclophagi (locust eaters). Just to show his scheme was not entirely based on diet, he threw in the Simi (flat nosed). It is unlikely that people actually thought of themselves as being Hylophagi or Simi.67* [67* - “.H. III.15.1; 21.1; 23.1; 24.1–2; 28.1–2; 29.1. On names the Greeks gave to the Libyans, see Olivier Masson, "Grecs et Libyens en Cyrenaique," Antiquités africaines 10 (1976): 49–62.” - Richard L. Smith]

Finally, a bio-anthropological trivia on Imazighen speaker...

Recaps from posts elsewhere: Language family association aside, the other thing that seems to tie in these groups, though perhaps relatively more loosely than the language connection, is reoccurring uniparental markers, that is suggestive of ultimate from descent a common recent ancestor in a proto-Amazighan speaking population; predominantly, from the paternal side, this is primarily the E-M81 marker, closely followed by various clusters of the E-M78 marker. On the maternal end, an interesting pattern is observed: a clinal distribution along geographic lines finds expression with recent European ancestry substantially represented along the the north coast regions, wherein its frequency thereof progressively fades as one proceeds further into the continent, through the Sahara to the Sahel, and ultimately into sub-Saharan Africa. By the same token, the more traditional/typical African markers are more considerably represented in Sahelian and Saharan Imazighen speakers. This maternal distribution pattern seems to parallel phenotypic trends like that of the clinal pattern invoked in skin tone variations; Imazighen (Berber) speakers sport noticeable degree of variation from tawny looking groups to noticeably dark hued groups, and intermediary grades in between the extremes of this phenotypic manifestation amongst Imazighen speakers; darker-toned Imazighen speakers seem to be predominant in the Saharan and Sahelian areas, while the coastal north regions is notably inhabited by considerable segments of populations, though not exclusively, of lighter-toned Imazighen and Arabized Imazighen speakers.

There have been attempts by some parties to tie contemporary Imazighen speakers with Upper Paleolithic bio-anthropological records of Northwest Africa, but genetic studies have shown that while contemporary Imazighen groups carry lineages that derive from Upper Paleolithic provenance, the coalescent ages from typical Amazigh markers postdate the Upper Paleolithic; reoccurring markers like M1 and U6 also derive from the Upper Paleolithic, but are not evenly distributed in considerable frequency in different Imazighen locales, if not even relatively modest compared to some territorially-specific markers of an Imazighen habitation in question. One study found something interesting in the coastal northwest African mtDNA landscape: that an Arabized population had less traditional African-specific markers than the "Imazighen"-identified counterpart in Tunisia; they attribute this interesting find to the "patchy nature" of DNA samplings undertaken on contemporary Imazighen populations...

Female gene pools of Berber and Arab neighboring communities in central Tunisia: microstructure of mtDNA variation in North Africa.
Feb 2005

North African populations are considered genetically closer to Eurasians than to sub-Saharans. However, they display a considerably high mtDNA heterogeneity among them, namely in the frequencies of the U6, East African, and sub-Saharan haplogroups. In this study, we describe and compare the female gene pools of two neighboring Tunisian populations, Kesra (Berber) and Zriba (non-Berber), which have contrasting historical backgrounds. Both populations presented lower diversity values than those observed for other North African populations, and they were the only populations not showing significant negative Fu's F(S) values. Kesra displayed a much higher proportion of typical sub-Saharan haplotypes (49%, including 4.2% of M1 haplogroup) than Zriba (8%). With respect to U6 sequences, frequencies were low (2% in Kesra and 8% in Zriba), and all belonged to the subhaplogroup U6a. An analysis of these data in the context of North Africa reveals that the emerging picture is complex, because Zriba would match the profile of a Berber Moroccan population, whereas Kesra, which shows twice the frequency of sub-Saharan lineages normally observed in northern coastal populations, would match a western Saharan population except for the low U6 frequency.

The North African patchy mtDNA landscape has no parallel in other regions of the world and increasing the number of sampled populations has not been accompanied by any substantial increase in our understanding of its phylogeography. Available data up to now rely on sampling small, scattered populations, although they are carefully characterized in terms of their ethnic, linguistic, and historical backgrounds. It is therefore doubtful that this picture truly represents the complex historical demography of the region rather than being just the result of the type of samplings performed so far.

Recalling from a previous posting elsewhere...

Arredi et al. had already stated that there is no substantial "Paleolithic" contribution in North African west Afrasan-speaking groups (otherwise known as "Berbers"), even though the lineages themselves derive from ancestral lineages of Paleolithic extraction; whereas the Bosch et al. study sees E3b lineages in Berbers as of Upper Paleolithic extraction. Arredi et al.'s study post-dates (2004) that of the Bosch et al. study (2001). Moreover, Bosch et al. idea of what constitutes "sub-Saharan" Africa is messed up, judging from their seeming incapacity to note that E3b-M35 is of sub-Saharan origin. Nonetheless, Wikipedia's claim about ancestry, supposedly in attribution to Bosch et al., is a far cry from what is actually presented in the Bosch et al. study; and so, in reading Wikipedia, caution has to be in order before one accepts the said info as credible. This is what was stated in Wikipedia:

The Y chromosome is passed exclusively through the paternal line. The composition is: 48% E3b2, 12% E3b* (xE3b2), 17% R1*(xR1a) and 23% F*(xH,I,J2,K) ((Arredi et al., 2004) [1]), according to the method used by Bosch et al. 2001. We may summarize the historical origins of the Kabyle Y-chromosome pool as follows: 60% Northwest African Upper Paleolithic (H36/E3b* and H38/E3b2), 23% Neolithic (F*(xH,I,J2,K)) and 17% historic European gene flow (R1*(xR1a)). :

This is what Bosch et al. actually said:

Group IX haplotypes (fig. 2gi) are found in the Middle East and are most prevalent in Europe (Underhill et al. 2000). Group IX also contains three local Iberian haplotypes: H101, H102, and H103. The latter, which is defined by derived mutation M167 (also known as "SRY-2627"), is equivalent to Y-chromosome haplogroup 22 as described by Hurles et al. (1999). These authors examined haplogroup 22 worldwide and showed that it has a geographical distribution almost restricted to northern Iberia. Moreover, on the basis of the dating of microsatellite and minisatellite diversity within haplogroup 22, they suggested that it arose in Iberia a few thousand years ago.

Group IX is found at a low frequency **(3%)** in NW Africa. In Iberia, 56% of the Y chromosomes carry H104, which is found across Europe, with increasing frequencies toward the west; its defining mutation, M173, may have been introduced by the first Upper Paleolithic colonizations of Europe (Semino et al. 2000). It may not have been the only lineage introduced into Iberia during the Upper Paleolithic, but it seems to have been the only one that has persisted in the extant Iberian gene pool. Of five H104 NW African chromosomes, one had an STR haplotype identical to that in an H104 Iberian chromosome, one was one mutation step away from Iberian H104 chromosomes, and the remaining three were two mutation steps away. Moreover, the mean repeat-size difference within 53 H104 Iberian STR haplotypes was 2.8 (range 011). The phylogenetic relations among H104 STR haplotypes is shown by a reduced median network (fig. 3c), in which the NW African chromosomes appear to be clearly embedded within the Iberian diversity. The time necessary to accumulate the STR-allele differences between NW African and Iberian H104 chromosomes was estimated at 2,100 ± 450 years. This close STR-haplotype similarity seems to indicate that H104 chromosomes found in NW Africa are a subset of the European gene pool and that they may have been introduced during **historic times.**


...meaning that European, more precisely Iberian male mediated gene flow, is much more recent in coastal North African west-Afrasan speakers, who are specifically the following:

H50 found in one Moroccan "Arab", and H104 found in one southern Moroccan "west-Afrasan/"Berber"" speaker, three Moroccan "Arab" speakers, and one north-central Moroccan "west-Afrasan" speaker.

Bosch et al. go onto conclude that:

So far, our analyses have allowed a clear dissection of almost all NW African and Iberian paternal lineages into several components with distinct historical origins. In this way, the historical origins of the NW African Y-chromosome pool may be summarized as follows: 75% NW African Upper Paleolithic (H35, H36, and H38), 13% Neolithic (H58 and H71), **4%** historic European gene flow (group IX, H50, H52), and 8% recent sub-Saharan African (H22 and H28). In contrast, the origins of the Iberian Y-chromosome pool may be summarized as follows: 5% recent NW African, 78% Upper Paleolithic and later local derivatives (group IX), and 10% Neolithic (H58, H71). No haplotype assumed to have originated in sub-Saharan Africa was found in our Iberian sample. It should be noted that H58 and H71 are not the only haplotypes present in the Middle East and that the Neolithic wave of advance could have brought other lineages to Iberia and NW Africa. However, the homogeneity of STR haplotypes within the most ancient biallelic haplotypes in each region indicates a single origin during the past, with possible minor reintroductions, with the Neolithic expansion, from the Middle East. Thus, Neolithic contributions may be slightly underestimated.

Whereby Hg E is denoted by the following:

H35=E3b-M78, H38=E3b-M81, and H36=E3b-M35; H22=E3a-M2, and H28=E1-M33

Hg J denoted by the following:

H58=J2*-M172

Hg F denoted by the following:

H71=F*-M89

Hg I denoted by the following:

H50=I1b2-M26, and H52=I*-M170.

Hg R denoted by the following:

H104=R*-M173

Thus note that the "4%" "historic", NOT pre-historic, European contribution quite likely from the Iberian peninsula, is a combination of I lineage (.6%), which was found in only one Moroccan "Arab" speaking individual AND R lineages (2.8%) found in five Moroccan individauls; three of them "Arab" speakers, and two of them "west-Afrasan" speakers.

Crania: Behind the "Generalized Modern human pattern" ...

Within 'Medi-centrist' circles, ideologues have sought psychological refuge in this anthropological catchword, in relation to cranial morphology; however, what is this term really a code word for? Well, let's examine from the language of a few anthropological publications, what this really boils down to...

The reactionary and outdated anthropological work of Colin Groves naturally comes to mind immediately:

...The implications of the Herto find for modern human origins are clear. Here were H. sapiens, more primitive than anyone now living but recognizably members of our own species, living in north-eastern Africa at a time when the Neanderthal people were in sole occupation of Europe. Even later than Herto, the only people for whom we have evidence were still non-modern - an enigmatic Neanderthal-like skull from Maba in China, and late H. erectus in Java. Just as predicted by the Out-of-Africa model, modern humans appear in Africa long before they are known from anywhere else.

There are implications for the origins of modern races, too. Herto (and Jebel Irhoud) are H. sapiens, but with primitive features. They are not, racially speaking, Africans. The later Omo and Klasies remains are more modern, but they too are archaic, and certainly show no traces of the features that characterize any modern races. Only Qafzeh and Skhul seem to lack these primitive features, and rate as “generalised modern humans”.

Our species seems to have existed as an entity long, long before it began to spread outside Africa or the Middle East, let alone split into geographic races.

When, then, did H. sapiens begin to split into races? The evidence indicates that modern racial features developed only gradually in each geographic area. The earliest H. sapiens specimen outside the Africa/Levant region is from Liujiang in China, whose dating was recently confirmed at 67,000 BP by a group led by Guanjun Shen of Nanjing Normal University. Like Qafzeh and Skhul, Liujiang is a “generalized modern”; it has no Mongoloid features.

The East Asian fossil record is not good enough to show when Mongoloid features began to develop. All we can say is that they must have developed before the end of the Pleistocene (12,000 BP) because this is when people began to cross what is now the Bering Strait (which was then a land-bridge); and Native Americans are Mongoloid.

H. sapiens began to enter Europe about 40,000 BP, but it is only at 28,000 BP that we get a fossil that shows any Caucasoid features - the Old Man from Cro-Magnon, in France.

Within the African homeland, the appearance of Negroid features is debatable. The skull from Border Cave, on the South Africa/Swaziland border, may be 60,000 years old and may show Negroid features, but both claims have been challenged.

And Australia? The earliest widely accepted dates for human occupation are of the order of 60,000 BP, not more, according to Bert Roberts of La Trobe University and the late Rhys Jones of the Australian National University. The claim that the Mungo Man skeleton is 62,000 BP has recently been challenged. According to a recent study led by Jim Bowler of Melbourne University, both Mungo Man and Mungo Woman may be only 40,000 years old (AS, April 2003, pp.18-21), but they are still the earliest skeletal remains we have from Australia. Are they Australoid?

Of all “major races”, Australoids have evidently changed least from the generalized modern human pattern, but the flat, receding forehead and angular skull vault that characterise many full-blooded Aboriginal people today are somewhat different to the Qafzeh/Skhul pattern. A 1999 study by Susan Antón and Karen Weinstein of the University of Florida, in the process of confirming that some of the Australian fossils (including most of the famous Kow Swamp series) had undergone artificial head deformation in infancy, found unexpectedly that most of the Pleistocene fossil Australian crania are rounder-skulled than modern ones. So racial features developed late in this part of the world, too.

In summary, the new discovery at Herto does not shatter any myths, but it extends the dataset, shifts the weight of evidence yet more decisively in favour of the Out-of-Africa model of modern human evolution, and helps to place modern racial variation very firmly into context.

Let's see what Groves says is not the "generalized modern human pattern":

— primitive features

...which Grove observes, is a feature of the Herto, the Omo and Klasies specimens; and to drive this point, Grove tells us that: The later Omo and Klasies remains are more modern, but they too are archaic, and certainly show no traces of the features that characterize any modern races.

Apparently, bespeaking of the outdatedness of his viewpoint, the Omo specimens that Grove deems more modern, are actually much older than the Herto specimen — that is, outside the fallacy of "human races".

What else is not generalized modern, according to Groves?

— Mongoloid features

...on which we are clued in, here: Like Qafzeh and Skhul, Liujiang is a “generalized modern”; it has no Mongoloid features.

What else?

— Caucasoid features

And we know this, because Groves tells us that: it is only at 28,000 BP that we get a fossil that shows any Caucasoid features - the Old Man from Cro-Magnon, in France.

Mind you, this would be the same "Caucasoid" Cro-Magnons that Chris Stringer tells us: more like present-day Australians or Africans, judged by objective anatomical categorizations, as is the case with some early modern skulls from the Upper Cave at Zhoukoudian in China

And with regards to which, Brace says: oft-repeated European feeling that the Cro-Magnons are “us” (46) is more a product of anthropological folklore than the result of the metric data available from the skeletal remains

We are also clued in that generalized modern isn't exactly....

— modern racial features...either!

Yeap, you probably guessed it; he implies this to us, right here: When, then, did H. sapiens begin to split into races? The evidence indicates that modern racial features developed only gradually in each geographic area.

Yet even by Groves' own rationale, although he turns around and simply says that it has been challenged, the so-called 'Negroid' trait preceded the so-called Caucasoid:

Within the African homeland, the appearance of Negroid features is debatable. The skull from Border Cave, on the South Africa/Swaziland border, may be 60,000 years old and may show Negroid features, but both claims have been challenged.

For if the said 'Negroid' features are attested to 60 ky ago, then that would apparently predate the questionable appearance of the so-called 'Caucasoid' features at ca. 28 Ky ago among the discredited "Caucasoid Cro-Magnons" , wouldn't it?!

But perhaps the most instructive piece of Groves' racialist discourse, is this:

Of all “major races”, Australoids have evidently changed least from the generalized modern human pattern, but the flat, receding forehead and angular skull vault that characterise many full-blooded Aboriginal people today are somewhat different to the Qafzeh/Skhul pattern.

It doesn't take much of a stretch of the imagination to see that Australian aborigines are tropically-derived peoples, with considerable skin eumelanin, placing them well within the range of skin pigmentations found across 'sub-Saharan' Africans. In popular language, we all know the latter are known as "blacks". Indeed, Groves' ability to see closer phenotypic link between Australian aborigines and Upper Paleolithic "Eurasian" specimens of Qafzeh/Skhul and Australia, is consistent with the aforementioned Chris Stringer et al.'s assessment:

"Nor does the picture get any clearer when we move on to the Cro-Magnons, the presumed ancestors of Modern Europeans. Some were more like present-day Australians or Africans, judged by objective anatomical categorizations, as is the case with some early modern skulls from the Upper Cave at Zhoukoudian in China

Stringer et al.'s observation is yet consistent with that of Neves et al. 2005:

"Increasing skeletal evidence from the U.S.A., Mexico, Colombia, and Brazil strongly suggests that the first settlers in the Americas had a cranial morphology distinct from that displayed by most late and modern Native Americans. The Paleoamerican morphological pattern is more generalized and can be seen **today** among **Africans, Australians, and Melanesians.**

Here, we present the results of a comparative morphological assessment of a late Paleoindian/early archaic specimen from Capelinha Burial II, southern Brazil. The Capelinha skull was compared with samples of four Paleoindian groups from South and Central America and worldwide modern groups from W.W. Howells' studies.

In **both analyses** performed (classical morphometrics and geometric morphometrics), the results show a clear association between Capelinha Burial II and the Paleoindians, as well as Australians, Melanesians, and Africans, confirming its Paleoamerican status."


Reminiscent of Groves' distancing of the generalized cranial morphology from the so-called 'Mongoloid pattern', Neves et al. tells us:

The increasing evidence that all late Pleistocene/ early Holocene human groups from South America are characteristically non-Mongoloid has major implications for the colonization of the Americas, as argued by one of us (WAN) since the end of the 1980s. Even if few studies with large samples from single sites have been carried out so far with Paleoindians (see Neves et al., 2003, 2004, as examples of these studies), it is evident by now that South America Central America and possibly North America, were populated by human groups with a more generalized cranial morphology before the arrival of the Mongoloids.

Like Stringer, they too see the generalized pattern as that akin to that seen in cranial morphology of tropical adapted groups like Australians, Melanesians and Africans:

— Since this more generalized morphology (‘‘Australo-Melanesian- like’’) was also present in East Asia at the end of the Pleistocene, transoceanic migrations are not necessary to explain our findings.

— As presented in detail elsewhere (Neves et al., 2003) the arrival of an ‘‘Australo-Melanesian-like’’ population in the Americas is easily accommodated under what is presently known about the place of origin and the routes taken by modern humans in their first long-distance dispersions (Lahr and Foley, 1998).

What Neves et al. tells us next, pretty much sums up why Upper Paleolithic African specimens show affinities with Upper Paleolithic 'Eurasians', as well as Paleo-Indians:

1) Accordingly, a population that began to expand from Africa around 70 ka reached southeast Asia by the middle of the late Pleistocene, carrying with it a cranial morphology characterized by long, narrow neurocrania and narrow, projecting faces.

2) We postulate that after reaching southeast Asia, this stem population gave rise to at least two different dispersions.

— 50 Ky ago
One took a southward direction and arrived at Australia around 50 Ka.


— Between 50 and 20 Ky ago
Sometime between 50 and 20 Ka a second branch dispersed towards the north, and arrived in the Americas by the end of the Pleistocene, bringing with it the same cranial morphology that characterized the first modern humans.

Neves et al.'s observations are apparently valid, and appears to be the consensus scientific finding, but even they fall victim to "idealized" typological constructs [as indicated by the need to refer to the term "Mongoloid" at all] — although to a much lesser degree than Groves — and it serves one to understand that when they speak of stronger phenotypic associations between Paleo-Indians and Paleo-Eurasians and contemporary dark-skinned tropically-adapted/derived groups like aboriginal Australians, Melanesians and Africans than other contemporary groups, that with regards to Africans, the comparison is being made with view to only a snapshot of African diversity. Take for instance, the following Neves et al. characterizations of the Paleo-Indian source populations:

Recap — Accordingly, a population that began to expand from Africa around 70 ka reached southeast Asia by the middle of the late Pleistocene, carrying with it a cranial morphology characterized by long, narrow neurocrania and narrow, projecting faces.

And then this — When the classical Mongoloid cranial morphology appeared in northeastern Asia, either as a local response to extreme environmental conditions, or as the product of a migration from northern Europe, a new expansion of northern Asians reached the New World, bringing with it a cranial morphology characterized by short, wide neurocrania and broad, retracted faces.

Although local microevolutionary processes in the Americas can not be precluded to explain the transition from a generalized to a very specialized cranial morphology (Powell and Neves, 1999), a model based on the entrance of two different morphological patterns from the Old World is much more parsimonious.

The two patterns are further described as follows...

The three different quantitative analyses undertaken in this study demonstrate that the first South Americans exhibit a cranial morphology that is:

1 — very different from late and modern Northeastern Asians and Amerindians (short and wide neurocrania; high, orthognatic faces; and relatively high and narrow orbits and noses)

2 — but very similar to present Australians/Melanesians and Africans, especially with the former (narrow and long neurocrania; prognatic, low faces; and relatively low and broad orbits and noses).

Source: Neves et al. 2005; Cranial morphology of early Americans from Lagoa Santa, Brazil: Implications for the settlement of the New World.

Clearly, the cranial patterns described in association with the Australian/Melanesian and African groups is only a snapshot of the actual overall diversity of Africans; the combination of traits described above is often invoked in what one might refer to as 'stereotypical Negro" — or as it has been referred to elsewhere — as "forest Negro". Certainly, these traits do not cover the full range of cranio-facial patterns observed across sub-Saharan Africans and Africans as a whole; they are just subsets of the said variation.

Revisiting that last 2nd point: 2 — but very similar to present Australians/Melanesians and Africans, especially with the former (narrow and long neurocrania; prognatic, low faces; and relatively low and broad orbits and noses).

It should be obvious from the above, that showing stronger phenotypic affinities with the above mentioned groups — Australians, Melanesians, and Africans, that this doesn't mean the said three groups show no inter-group differences; apparently, there are discernible phenotypic manifestations between them, with contemporary Australians and Melanesians perhaps showing somewhat stronger links to the aforementioned Paleolithic specimens than contemporary Africans, but relatively smaller distances between the three contemporaries and the Paleolithic specimens, than the case may be with other groups; this brings us to the:

Conclusion: Stronger phenotypic associations are observed between the modern tropically-adapted/derived groups like Australians, Melanesians and Africans and Paleolithic groups of Africa, Eurasia and America, because original modern humans were tropically-adapted Africans, who sported considerable skin pigmentation — that is to say, "blacks". Therefore, the 'generalized modern' is nothing more than a code word or just another euphemism for a variant(s) of the [naturally, dark-skinned] tropical African, otherwise also called "black African". This applies to their tropically-adapted Paleolithic descendant populations in the Levant, SouthAsia, Europe, and the Americas. The generalized moderns represent part of the then existing overall variation of tropical Africans, just as the "stereotyped" or "idealized" sub-Saharan African archetype constitutes just a part of overall phenotypic diversity of Saharo-Sub-Saharan Africa.

Ps — Some Eurocentric ideologues, as exemplified in Groves' work, unable to psychologically come to grips with their ultimate derivation from dark-skinned [tropical] African ancestors, conjure up pseudo-scientific "racialist" or typological discourse wherein they seek to mystify the fact by hiding behind code terms like "generalized modern", even if it means contradicting themselves in the process — again as Groves did — and overlooking it. For instance, from Groves, one almost gets the sense that he tries too hard to make a case that the generalized modern is a type which is spared so-called archaic features, yet distinctive from 'contemporary' populations which he divides and classifies into rigid types, while at the same time, acknowledging a relatively stronger association with the contemporary likes of aboriginal Australians. It doesn't take a genius to figure out that aboriginal Australians are considerably dark skinned peoples, whom like other tropical-affiliated groups like Melanesians, are in certain ways reminiscent of their dark skinned African brethren, not to mention sporting strong morphological affinities with both Paleo-'Eurasians' and Paleo-Africans, because they all emanate from autochthonous dark skin ancestral populations of tropical Africa — a fact which is relayed through cephalo-morphometric study, as just examined, and molecular genetics — wherein relatively deeper monophyletic units or markers are attested to in these groups [especially Africans] than those observed in their counterparts elsewhere!
