[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by Tukuler: [qb] Old comments on nrY may not apply today if only letternumber IDed instead of letternumbermutation. Y Consortium keeps track of letternumber chamges over the years as improved methodologies and sampling has yielded more sub-haplogroups. So the Y tree is not static. The mutation never changes. That's why it's the prefered way to ID MSY clades.[/qb][/QUOTE]Yeah that's what I thought. So they refined the NRY classifications. Of course it seems they mainly do this with E clade-- the one clade that bridges Sub-Saharans to Eurasians. [QUOTE][qb]____________________________________________________ Stumbled across the remains used to compose some of the Lazaridis/Reisch acronymed "genomic groupings". Can't recall how I compiled it but the main thing is is it correct. Then the other acronyms need the same treatment if applicable. I mean I accept data pooling much more readily than statistical entities, not saying such don't sometimes "predict" remains not yet found. Is ANA laid out anywhere as succinctly as here? [IMG]https://i.postimg.cc/ydvnhgZN/picture-35-50.png[/IMG] [IMG]https://i.postimg.cc/FzzpTryV/picture-36-43.png[/IMG] [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=008823;p=16#000758]www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=008823;p=16#000758[/URL] So of these initial finds is it only WHG EEF and ANE based on human remains? BE and ENA don't look like from any sampled aDNA? [/qb][/QUOTE]Basal Eurasian was at first only hinted at in living populations of the Middle East and was only later confirmed by the Dzudzuana study. The same with with ENA. ENA diverged from BE, with ENA having its highest frequency in Eastern Eurasian populations. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4170574/ [IMG]https://media.springernature.com/full/springer-static/image/art%3A10.1038%2Fnature13673/MediaObjects/41586_2014_Article_BFnature13673_Fig1_HTML.jpg[/IMG] [IMG]https://media.springernature.com/lw685/springer-static/image/art%3A10.1038%2Fnature13673/MediaObjects/41586_2014_Article_BFnature13673_Fig2_HTML.jpg[/IMG] [i] [b]Map of West Eurasian populations and Principal Component Analysis[/b] (a) Geographical locations of analyzed samples, with color coding matching the PCA. We show all sampling locations for each population, which results in multiple points for some (e.g., Spain). (b) PCA on all present-day West Eurasians, with ancient and selected eastern non-African samples projected. European hunter-gatherers fall beyond present-day Europeans in the direction of European differentiation from the Near East. Stuttgart clusters with other Neolithic Europeans and present-day Sardinians. MA1 falls outside the variation of present-day West Eurasians in the direction of southern-northern differentiation along dimension 2.[/i] As for ANA, the label was never coined by Lazaridis himself but by others who first noticed this differentiated signal from BE and other West Eurasian signals in the Dzudzuana study. [QUOTE]Originally posted by Yatunde Lisa: [qb] Pastorilists tend to adopt languages... Pul, Fula may have adopted Niger Congo... I am sure Somalia is connected to ancient Egypt... but that does not diminish other groups connection to ancient Egypt.. Egypt has been removed from Africa by Eurocentrist and racist egyptologist... But by studying different West African groups and their own oral histories, cultures and folk ways those connections and ties are there... for those who are looking and want to make the connections for those who don't they won't look because they don't want those connections to be made Schrodinger's cat and all that.. [/qb][/QUOTE] [QUOTE]Originally posted by BrandonP: [qb] We'll need more aDNA samples from ancient Egypt to see which African groups they would be most closely related to. I suspect the majority of their African ancestry is going to be local to northeastern Africa (i.e. something like "Basal Eurasian" or ANA), but they might have at least a little admixture from southern Sudanic Nilotes as well as maybe an Omotic-like population. However, I would not rule out some ancestry being shared between Nile Valley and West African populations via the Green Sahara, especially since we know the latter have some ANA ancestry. [/qb][/QUOTE]That Fulani have ANA was first noticed as far back as 2012 by the likes of Razib Khan in his Discover Magazine article [URL=https://www.discovermagazine.com/the-sciences/the-fulani-have-an-old-berber-element]The Fulani Have an Old "Berber" (?) Element[/URL] [i] The Fulani (Fula) people of the western Sahel seem to have a relatively old West Eurasian component which has distinct affinities with the "Maghrebi" element discerned by Henn et al. In fact, the non-Sub-Saharan African ancestry of the Fulani is almost exclusively of this origin. To me this serves as a peculiar mirror of what you see in the Cushitic and Ethiopian Semitic peoples of the far east of the Sahel-Sudan latitudinal region. These populations also seem to be compounds of a Sub-Saharan Africa element with a West Eurasian one, but in their case the admixture is almost exclusively from a Southwest Eurasian (Arabian) component. Geographically these two symmetric admixture events make sense, but the exclusivity is still a bit surprising. Additionally, in both the case of the Fulani and the Ethiopian and Cushitic groups the admixture is widely distributed and even enough to imply that they are old events. I also assumed this because in some admixture runs a "pure" Fulani cluster partitions out, which is not unexpected for stabilized hybrid populations (all human populations are stabilized hybrids if you go back far enough).[/i] [IMG]https://images.ctfassets.net/cnu0m8re1exe/3hL6ckqPomt3Lc0xms3N03/1df1789161f5eb30227c1d94f9b41324/fula1.png?fm=jpg&fl=progressive&w=660&h=433&fit=pad[/IMG] [IMG]https://images.ctfassets.net/cnu0m8re1exe/6hUJAabO9GMsQkkfJjXoJq/538cf7f3e059cf1c66e14831fa25e2fa/fula2.png?fm=jpg&fl=progressive&w=660&h=433&fit=pad[/IMG] This was later confirmed by 2015 Triska et al. [URL=https://core.ac.uk/download/pdf/55640002.pdf]paper[/URL] that I cited [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=010239;p=2]before[/URL].
