Africans are all the same …North and South. End of the divide?
Nomadic pastoralists and sedentary farmers of the Sahel/Savannah Belt of Africa in the light of geometric morphometrics based on facial portraits Karel Kleisner1 Viktor Černý2,3
Abstract
Objectives: The Sahel/Savannah belt is a region where two sympatric human subsistence strategies—nomadic pastoralism and sedentary farming—have been coexisting for millennia.While earlier studies focused on estimating population differentiation and genetic structure of this ecologically remarkable region's inhabitants, less effort has been expended on understanding the morphological variation among local populaton
Materials and methods: To fill this gap, we used geometric morphometrics to analyze the facial features of three groups of pastoralists and three groups of sedentary farmers belonging to three language families (Niger-Congo, Nilo-Saharan, and Afro- Asiatic) whose mitochondrial DNA sequences have been published previously. Results: Our results show that pastoralists differ from farmers with several facial features. We also found that individuals who bear maternally inherited haplotypes of Eurasian ancestry do NOT significantly morphologically differ from individuals whose maternal ancestry is sub-Saharan.
Conclusions: Our study follows up and builds upon population genetic and phylogeographic studies of Eurasian haplogroups in the Fulani pastoralists and sub- Saharan haplogroups in the Arab pastoralists, as well as studies on the spread of lactase persistence mutations and other genetic markers. Our results suggest that recent gene flows across the Sahel/Savannah belt were not strong enough to erase a genetic structure established by Paleolithic foragers and further shaped by the adoption of agropastoral food-producing strategies.

What are they telling us? Well...It looks like certain morphological features existed in North Africans and southern Saharans since the Paleolithic period. The maternal lineage whether "Eurasian" or "SSA" has no impact on morphology. In other words...."Eurasian" lineage has no impact what an individual "looks" like.

Quotes: “However, no research was undertaken if these Eurasian uniparental lineages are associated with a physical appearance of the Sahelian peoples.” " As mentioned above one group of nomadic pastoralists is represented by the Fulani that inhabits mainly the western part of the Sahel and speaks a Niger-Congo language of West African origin (Blench, 2006; Ehret, 2002). They attracted the attention of numerous scholars by owning large herds of humped zebu cattle which was introduced to Africa from India??? (Mwai, Hanotte, Kwon, & Cho, 2015) and by having facial features reminiscent of Eurasian appearance (Dupuy, 1999; Hiernaux, 1975; Newman, 1995). It is therefore not surprising that efforts have been undertaken to search for their ancestry out of their current Sahelian habitat, especially in North Africa, Ethiopia, or even Eurasia (McIntosh & Scheinfeldt, 2012).

"The dominant group of nomadic pastoralists in the eastern part of the Sahel are Arabs, descendants of numerous Bedouin tribes who migrated from the Arabian Peninsula?? from the seventh century AD onwards by two routes: along the Nile Valley southward or and along the Mediterranean coast and then across Saharan oases, such as Ghadames and Bilma, all the way to Lake Chad (Braukämper, 1994; Cunnison, 1966; MacMichael, 1922; Zeltner, 2002)." "And last but not least, the Niger-Congo peoples, represented in our dataset by the Fali who belong to the Adamawa branch (Gauthier, 1979), have, linguistically speaking, clearly West African origin like the Fulani and this is where most of these languages and their diversified variants are still present." "Morphological or anthropometric studies of African populations have reported a correlation between some metric variables and the climate (Hiernaux & Froment, 1976)." " Bizygomatic width tends to increase with air moisture and climate uniformity, while nose height tends to decrease in wetter regions. Hiernaux and Froment 1984 have also reported—in a paper describing 10 contemporary populations of the Niger bend, mainly in the north and south of Burkina Faso—that Sahelian men who live in areas where the annual rainfall is around 400 mm have a shorter and wider head and a longer face, and Sahelian women a narrower face, than southern populations living in areas with rainfall around 800 mm. Nose measurements follow the same pattern of differences in both sexes that is, Sahelians have a longer and narrower nose than populations in drier areas further south (Froment & Hiernaux, 1984)." "Due to a limited number of studied groups, however, this discussion focused on cold-dry versus hot-humid environments, without investigating specifically the contrast between hotdry and hot-humid environments, such as are frequently found in Africa (Noback, Harvati, & Spoor, 2011). More recently, this gross climatic association has been explored in a detailed three-dimensional study of nasal shape, which involved 476 living subjects from Africa, Europe, and northern and southern Asia, and confirmed a non-neutral pattern across human populations (Zaidi et al., 2017)."

" In this study, our goal was to determine whether the genetic differences between populations belonging to two sympatric foodproducing economies, which were identified by molecular genetic studies (Černý et al., 2007, 2011; Čížková et al., 2018; Triska et al., 2015), can also be found by morphometry. The main question was if the nomadic pastoralists coming from the north show, in comparison with sedentary farmers, morphological traits related to a drier climate, such as a narrower face and nose. Also, thanks to phylogeographic classifications of mtDNA haplotypes which links them to either sub- Saharan or Eurasian ancestry, we wanted to know whether individuals bearing Eurasian mtDNA show also facial differences from individuals who bear mtDNA of sub-Saharan ancestry. Positive answer to such question would suggest very recent admixtures of Eurasian and sub- Saharan gene pools formally divided by the Sahara. For these purposes, we used facial portraits depicting several peoples living in the Sahel region, which were collected during field research and mtDNA datasets published before. Thanks to this large and never published photographic dataset, we were able to evaluate the differences and similarities between nomadic pastoralists and sedentary farmers in both men and women and improve our understanding of the spread of food production economics in sub-Saharan Africa.

Conclusion
"In this study, we have shown several aspects of the facial morphology of two sympatric populations living in the African Sahel belt. In comparison to farmers, pastoralists show traits related to a drier climate, such as a narrower face and nose, what can be related with desertification had not allowed further existence of the cattle keepers. At the same time, thanks to phylogeographic classifications of mtDNA haplotypes which links them to either sub-Saharan or Eurasian ancestry, we were able to show that individuals who bear mtDNA of Eurasian origin do not show any facial differences from individuals who bear mitochondria of sub-Saharan ancestry so that the migration must has been rather ancient. These and other results are interesting in the context of African past climatic changes, spread of pastoralism and farming, and migration patterns between the communities of different lifestyles all that within the dynamically changing environment of the Sahel belt."

In other words they have concluded that Africans who live in humid tropical regions have similar morphological features whether they carry SSA or "Eurasaian" lineage. Geography dictates what an African "look" like. THERE IS NO RACE!!!...or racial ethnicity.
GEOGRAPHY DETERMINES Morphological features!!! always had. Nature Rules!!!

Hmmm reminds me of a old report on Fulani stating those with so-called EurSWAsian genomics weren't the ones with the 'exoctic' looks. I think it was a Černý authored article.
I waver on id by phs anth since joining ES 15 yrs ago. I subscribed to both craniology and craniometry previously. Even charting and illustrating AC Haddon and R Dixon for my 'notebook/index cards' back last century.
Today my trust is more in discrete non-metric facio-cranial assessment.
Got anecdotes if it's OK.
Mensa, don't forget that trans Sahara Y hg report we all were gonging on ES last year. Think it's relevant to your thread.
Sahel-savanna Fishers, pastors, farmers, and agro-pastoralists all of them have West African Monsoon optimum / African Humid Period Sahara ancestry as much as 15,000 yrs old.

Good find. This is what we have been saying for years on Reloaded/ES citing studies in support. This latest just confirms that.

I am glad the study authors are honest enough to address things like how narrower noses are heavily related to climate- like the drier desert belt which fosters narrower noses, rather than than obfuscate and play up the "true negro" stereotype. Again, what we have been saying for years. Things like narrow noses are just as "African" as broad noses and do not need any "race mix" or "back migration" to explain them away. Just climate itself over time will create said noses. Racialists of course don;t want to face the fact of African diversity as it debunks several cherished narratives, but there are also those who know better, including certain academics, that still trade in stereotypes.
I wish more black folk applied themselves to grasp such things rather than accept the racialist narratives an stereotypes of society- such as automatically assuming that somebody be "mixed" just because they have a narrower nose or features. Older folk who did not have today's dataset, yes I understand, but the younger generation should be up on such things. Alas it seems a fair amount of time is spent on diversionary matters- cats on Facebook talking bout mystical Atlantis and how it links to Kemet, or mystical star chambers in the pyramids linked to ancient astronaut energies etc etc. These were black folk doing this. Yes, I know blacks have their own share of kooks and cranks like everyone else, and yes some people might be approaching from a religious/faith-based format, but given widely available, credible info, I can't help wondering if some of these people are not "plants".. How often they appear in some places, setting up bogus strawmen, that can be easily "refuted"..

Geography dictates what an African "look" like. THERE IS NO RACE!!!...or racial ethnicity. GEOGRAPHY DETERMINES Morphological features!!! always had. Nature Rules!!! The only question about this conclusion is that it appears to follow the Western model of the peopling of Africa, which we know is false! The notion that so called "West Africans" have their unique morphology due to wet humid climate is based on a false model of our story. They continue to try to deny the fact that all Africans with the exception of the Khoi and the Twa, but including Nilotes, Niger-Congo speakers, and Cushitic Africans resided in North-Northeast Africa (particularly the latter) for thousands of years prior to migrating into "Sub Saharan Africa". In fact it has been proven that "Sub Saharan West Africa" was uninhabitable swamp land until around 5 thousands years ago per McIntosh & McIntosh 1981 ,1986. The entire notion of "West-Central Africans gaining their unique features as a result of climate their attempt to throw us off with their weak Western lies. For example
Notice these wide features that they claim are "adaptations to wet humid environment" were in place when the population in the main (save for the Mande who had been in Sahelian Western Africa since the drying of the Sahara) resided in hot dry Northeast Africa; If this migration depicted below did not occur until after the 1st millennium BC (which we know it) Then their entire argument is debunked. In fact the Nazlet Khater man which is the oldest skeleton in Kemet dating to that hot dry Northeast African environment since 33,000 years ago shows the same strong features as a "Negroid" individual who these studies say only came about due to a long habitation in a wet humid "West African" environment.
My point is that we have to IGNORE their insistence on controlling the narrative. As we can see they are full of sh*t from front to back.

www.youtube.com/watch?v=aOtLCXM8Ox8....prehistoric humans and dinosaurs in Antartica? I agree we need to ignore their control of the narrative. They have been proven wrong many times over. I believe the historical geography of the earth is different to what we see in pop culture/pop media. Saharans were probably pushed south and north during the desertification. But adaptation is a fact.......west africans, East africans or Eurasians?

Population history and genetic adaptation of the Fulani nomads: Inferences from genome-wide data and the lactase persistence trait Mário Vicente, Edita Priehodová
1 Abstract 2 Human population history in the Holocene was profoundly impacted by changes in 3 lifestyle following the invention and adoption of food-production practices. These 4 changes triggered significant increases in population sizes and expansions over large 5 distances. Here we investigate the population history of the Fulani, a pastoral 6 population extending throughout the African Sahel/Savannah belt. Based on genome 7 wide analyses we propose that ancestors of the Fulani population experienced 8 admixture between a West African group and a group carrying both European and 9 North African ancestries. This admixture was likely coupled with newly adopted 10 herding practices, as it resulted in signatures of genetic adaptation in contemporary 11 Fulani genomes, including the control element of the LCT gene enabling carriers to 12 digest lactose throughout their lives. The lactase persistence (LP) trait in the Fulani is 13 conferred by the presence of the allele T-13910, which is also present at high 14 frequencies in Europe. We establish that the T-13910 LP allele in Fulani individuals 15 analysed in this study lies on a European haplotype background thus excluding parallel 16 convergent evolution. Our findings further suggest that Eurasian admixture and the 17 European LP allele was introduced into the Fulani through contact with a North African 18 population/s. We furthermore confirm the link between the lactose digestion phenotype 19 in the Fulani to the MCM6/LCT locus by reporting the first Genome Wide Association 20 study (GWAS) of the lactase persistence trait. We also further explored signals of recent 21 adaptation in the Fulani and identified additional candidates for selection to adapt to 22 herding life-styles.

Horseshit
What in hell happened to Černy? Is Diallo a sycophantic fool?
This preprint is what you call a stacked deck. How are Burkinabe Fulani the single best representatives of the Hal Pulaaren and Fulfulde nation? Why when they'll yield a priori results. Throw all other Fulani suit cards away; the Tekrur (Futa Toro) foundation, but especially the Fulani in Sudan who bear up to 10,000 year old T-13910. They ain't slick. We ain't stupid.
Schlebusch & cruddy bastards pulling their horse hair over our woolly heads. "Lynch" Diallo, the traitor selling out for 💰. You don't betray your people to keep your belly stuffed and water in your swimming pool.
Tired of yte sloppy scholar eurocentrix monkey funkers & their dirty self serving lies.
Enemies: the Clash of Races Haki Madhubuti (1978) [inescapable analysis based conclusions]
T-13910 is oldest in Fulani. Early SE Algeria art proves Fulani had cattle first in the early and mid Holocene Tropical N Afr aka the phoney label "Green Sahara". That art even depicts the Fulani calf rope.
Proofs were provided 5 years ago on ES but I'll be damned if Ima track down and xfer the data to here. Let somebody else do it. Tired of posting googabs of info that nobody replies to nor even so little as to give thanks by clicking the like icon.
Independent ADMIXTURE program, run by a USA self-described negro, proved the distinct Fulani genome existed in the Neolithic Levant. Mykenaeans had it. And do I really need to add all N Afrs carry the Fulani genome except one ethnic group in Tunisia?
