----------------- www.genomeweb.com/sequencing/stone-age-moroccan-genomes-reveal-sub-saharan-african-near-eastern-ancestry#.WqvGimrwa70 Quote: “NEW YORK (GenomeWeb) – New genome sequence data from North African individuals living up to 15,000 years ago suggests that Stone Age Moroccans carried ancestry from both sub-Saharan Africa and the Near East. "Our analysis shows that North Africa and the Near East, even at this early time, were part of ONE region without much of a genetic barrier," co-senior author Choongwon Jeong, a researcher in the Department of Archaeogenetics at the Max Planck Institute for the Science of Human History, said in a statement. As they reported online today in Science, Jeong and colleagues from…” ---------------------- About 6 years ago I posted something like this. The Levant is an extension of Africa. That is why modern Levant do NOT cluster with the Neolithic Levant or Natufians. Henn and DNATribes and XYYMAN knew this. Pay me a dollar $ 10?  I hate to say it Coon but was right(somewhat) to some extent and so too was Sergi. Europeans are a subset of Africans. |

My-man they mention Mende and Yoruba and stated that it is an uncharactized lineage related to these two populations. Meaning?! Skoglund! Mende and YRI are a mixture of an older African lineage, older than Khoi-San, and Neolithics. Coon? Europeans are a mixture of Paleolithic Europeans and African Neolithics. There never was any back-migration. NEVER! www.sciencedaily.com/releases/2018/03/180315141221.htm Scientists discover genomic ancestry of Stone Age North Africans from Morocco Ancient nuclear DNA from 15,000-year-old modern humans from Morocco, the oldest ever recovered from Africa, shows dual genetic ancestry to ancient Near Eastern and to sub-Saharan African populations Date: March 15, 2018 Source: Max Planck Institute for the Science of Human History Summary: An international team of researchers have sequenced DNA from individuals from Morocco dating to approximately 15,000 years ago. This is the oldest nuclear DNA from Africa ever successfully analyzed. The study shows that the individuals, dating to the Late Stone Age, had a genetic heritage that was in part similar to ancient Levantine Natufians and an **uncharacterized** sub-Saharan African lineage to which modern West Africans are genetically closest.QUOTE: “Sub-Saharan heritage from a previously unknown ancient populationThough the scientists found clear markers linking the heritage in question to sub-Saharan Africa, no previously identified population has the precise combination of genetic markers that the Taforalt individuals had. While some aspects match modern Hadza hunter-gatherers from East Africa and others match modern West Africans, **neither** of these groups has the same combination of characteristics as the Taforalt individuals. Consequently, the researchers cannot be sure exactly where this heritage comes from. One possibility is that this heritage may come from a population that no longer exists. However, this question would need further investigation.” |

Quote:
“We analyzed the genetic affinities of the Taforalt individuals by performing principal component analysis (PCA) and model-based clustering of worldwide data (Fig. 2). When pro-jected onto the top PCs of African and West Eurasian popu-lations, the Taforalt individuals form a distinct cluster in an intermediate position between present-day North Africans (e.g., Amazighes (Berbers), Mozabite and Saharawi) and East Africans (e.g., Afar, Oromo and Somali) (Fig. 2A). Consist-ently, we find that all males with sufficient nuclear DNA preservation carry Y haplogroup E1b1b1a1 (M-78; table S16). This haplogroup occurs most frequently in present-day North and East African populations (18). The closely related E1b1b1b (M-123) haplogroup has been reported for Epipaleo-lithic Natufians and Pre-Pottery Neolithic Levantines (“Le-vant_N”) (16). Unsupervised genetic clustering also suggests a connection of Taforalt to the Near East. The three major components that comprise the Taforalt genomes are maxim-ized in early Holocene Levantines, East African hunter-gath-erer Hadza from north-central Tanzania, and West Africans (K = 10; Fig. 2B). In contrast, present-day North Africans have smaller sub-Saharan African components with minimal Hadza-related contribution (Fig. 2B).”
Xyyman comment: So the Great Lakes people from Tanzania were the precursor to BOTH Levantine Neolithics and North African Neolithics(leading to modern European Neloithics). Turks came in(1200AD) and diluted the North Africa population.
I am surpised Haak and Paabo penned their name to this Eurocentric cluster. Can of worms indeed.....The end?

“Two derived allele variants in the SLC24A5 gene associated with predicting light-skin color in individuals with European and South Asian (Indian, Pakistani) ancestry are rs1426654 (derived state A, ancestral state G (94)) and rs16891982 (derived state G, ancestral state C (95)). Individuals with a homozygous derived state for both these SNPs have been found in early Neolithic populations (Anatolia, Europe) (16)). Our results show that these derived alleles are absent in the Taforalt individuals analyzed; all of them have a homozygous ancestral genotype for both SNPs. The derived mutation for rs12913832 in the OCA2 gene is associated with blue eye color. A homozygous derived allele state at this position is the dominant determinant of light eye color in present-day Europeans and occurs at 100% frequency in Mesolithic hunter-gatherers (96, 97). Individuals with the ancestral allele A (homozygous or heterozygous) for this SNP show brown eye color 80% of the time (97). For all the Taforalt individuals we find a homozygous ancestral genotype GG, predictive of brown eye color. In addition, all individuals show the ancestral GG genotype for SNP rs12896399 located in the SLC24A4 gene, providing further support for dark eye pigmentation (93). The TCHH1 gene codes for trichohyalin, a protein active in hair follicle roots. For all Taforalt individuals we find the derived homozygous AA genotype for SNP rs17646946 in this gene, which has been associated with straighter hair in Europeans (allelic effect (β) = 0.4-0.5, explained variance = 6.11%) (98).
Xyyman comment: Wow! Black skin, black hair, black eyes but straighter hair . Ish-Gebor posted that pictures of Taforalt. Europeans do not have ownership of straight hair. I said before straight hair may be ancestral to kinky hair. It may be a new phenomenon. But black skin made us humans. Even the Paleolithic Europeans were black. So we are back to Dravidian type peoples?

To those who don’t get the visuals. All humanity was black skinned from Africa to Northern Europe during the Paleolithic to the early Neolithic. North Africans and Europeans ….and the Levant were black. And shockingly the Neolithics originating close to Tanzania brought the mutation for light skin beginning mid-Neolithic into North Africa, Southern Europe, Arabia, Pakistan and North Europe. We still need to resolve the East Asians.

As I said many times. These papers are very revealing. Here is something that may have been overlooked. That Hadza component is found in not only Tafofalt(~16000 years ago) but also Luxmanda(3100years ago), But traces are found in the Neolithic Levant Iran and Western HG, Including Mota. It is about 10% in modern Amazigh but ABSENT in Mende and Yoruba. Of course Mende, Yoruba and Hadza are all sub-saharan Africans. I would to see Eastern Hunter gatherers included in the mix. They weren’t. I would like to see East Asians included also in that same Admixture chart. My guess is there will be an increase to the East.  |

I believe it was someone of ES, T-rex?, that made the statement that these researchers do NOT keep update or have current studies at their disposal when they publish their papers. And I vehemently disagreed with him. Now in this paper they are claiming that WHG(ancient Western Europeans HG), has no genetic relation to Tarforlalt. But we have paper recently publish not too long ago. Now if we(laymen) can keep up why wouldn’t or can’t , the “experts’. After all we would think that they should be reading these papers day-in-day-out. But WHG is found in North Africa and points south of the Sahara. Black component(WHG-Loschbour) is found in Africa including the Canary Islands. When did this occur?  |
