[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by Archeopteryx: [qb] Hopefully better techniques to retrieve and analyze DNA from human remains will help to also see how those ancient people looked like. Already now they start to try to assess phenotype from DNA out of just fragments of skeletons, and soon perhaps also from eDNA. Interesting is that they tried to make some kind of reconstructions from the autosomal DNA from three of the Abusir specimens. See this thread: [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=15;t=013243#000000]Forensic and facial reconstructions[/URL] From the thread: [IMG]https://i.ibb.co/58fsXjM/Ancient-Egyptians-DNA-Phenotype.png[/IMG] Even the phenotype of the Denisovans has been predicted by DNA analysis [IMG]https://i.ibb.co/BBLjL49/Denisova-DNA.jpg[/IMG] [QUOTE] Now, in an impressive feat, Gokhman and his colleagues have mapped out a proposed Denisovan skeleton using information for 32 skeletal features encoded in DNA that was extracted from a pinky bone. The research, published today in the journal Cell, doesn’t give exact values for Denisovan proportions, but it does offer a comparative look at how this mysterious kind of hominin measured up against Homo sapiens and Neanderthals.

Even Egyptologists like Kara Cooney say that Abusir especially in the Late Period from whence these samples come from was settled by foreigners, mostly Asiatics. [IMG]https://qph.cf2.quoracdn.net/main-qimg-20e5aef10c4f1199a0508f4dcab4cecd[/IMG] As explained earlier in this thread, light skin was introduced to the Maghreb during the Late Neolithic in association with the introduction of Cardial Ware from Europe. Before that, the Early Neolithic peoples of that region as exemplified by IAM remains seem to have had dark that is melanated skin judging by their autosomal genes. Hence the reconstructions below. https://twitter.com/ChaouiAl/status/1467871652188938248/photo/1 [IMG]https://qph.cf2.quoracdn.net/main-qimg-91b2c5f31825bef98fd74d570d067326-lq[/IMG] Here is Fregel's PCA chart showing population relations via autosomes. [IMG]https://i.postimg.cc/CLtVSRQP/Fregel2018-PCA-redux-ES.png[/IMG] ^ Note that IAM is closest to Taforalt and both are intermediate between East African Luxmanda on end and Natufians on the other. Speaking of which, Natufian autosomal DNA also indicates that melanated skin was also not uncommon and that this complexion was even conserved by some Neolithic individuals (PPB). [IMG]https://qph.cf2.quoracdn.net/main-qimg-8dcb5367909b703ac3a70d28ac582ce0-lq[/IMG] So you had dark skin in Northwest Africa in one end and dark skin in the Levant on the other end yet the indigenous people of Northeast Africa/Egypt are somehow light-skinned? Especially since a German team back in 2005 did a [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=15;t=003765]melanin dosage test[/URL] on mummies: 2005, Vol. 80, No. 1 , Pages 7-13 (doi:10.1080/10520290500051146) A-M Mekota1 and M Vermehren2 [i] Skin sections showed particularly good tissue preservation, although cellular outlines were never distinct. Although much of the epidermis had already separated from the dermis, the remaining epidermis often was preserved well (Fig. 1). [b]The basal epithelial cells were packed with melanin as expected for specimens of Negroid origin.[/b]..[/i] [/QB][/QUOTE]
