[QUOTE]Originally posted by Antalas: [QB] [QUOTE]Originally posted by Swenet: Probably is not going to do me any good to point this out (I have already pointed this out to you, before, and pointing things out on anthro fora is generally a waste of time in my experience as shown by explained subjects reverting back to square one, like the Groundhog Day movie). But if you want to talk about misconceptions... If you look at the Taf and Afa samples in that Irish PCA, that's roughly where 'unmixed' Europeans and Middle Eastern Mesolithic HGs would be, before the [URL=https://media.springernature.com/lw685/springer-static/image/art%3A10.1038%2Fnature19310/MediaObjects/41586_2016_Article_BFnature19310_Fig3_HTML.jpg]homogenization of West Eurasia that took place in the holocene[/URL]. So Nubians plotting where they do with respect to SSA samples is part of a larger set of reasons that also involves Europeans and Middle Easterners no longer being anywhere close to West Eurasian hgs. At this point, you're just exploiting false appearances that are a recent thing (they only arose in the holocene and have no real antiquity as shown by the large distance of the pre-holocene Afa and Taf samples in your PCA). At least Nubians can be linked to populations in Africa by 17ky ago. What Palaeolithic populations can modern European and Middle Easterners be linked to? Nothing older than Natufians, and even Natufians don't look like modern Euros or Middle Easterners, [URL=https://i.imgur.com/oYJsrP9.png]as I've already explained to you.[/URL] [/QB][/QUOTE]How does this relate to any points raised in this thread ? And in what way does it dispute the content of my previous post ? Your response seems to lack concrete arguments to challenge the clear fact that whether you like it or not none of these ancient populations align with the majority of modern SSAs.

Nothing older than Natufians, and even Natufians don't look like modern Euros or Middle Easterners [/QUOTE]I'm not sure what you mean exactly by this, as such links can be inferred for most global populations. However, when it comes to certain aspects of their morphology, there is no apparent connection, and the distinctions are quite evident when compared to their Mesolithic ancestors : [QUOTE]Here we investigated the patterns of craniofacial and mandibular variation from Mesolithic hunting-gathering to late farming (in Lower Nubia), a period spanning 11,000 years. … [b]Our results highlight a strong morphometric distinction between Mesolithic hunter-gatherers and farmers[/b] … This study corroborates a major biological change during the transition from hunting to farming (…) Our results clearly depict a strong craniofacial and mandibular distinction in size and shape components between Mesolithic hunter-gatherers and early and late farmers. ... the cranial results align with the predictions of the “population influx” hypothesis at the point of transition from hunter-gathering to farming [/QUOTE] https://www.nature.com/articles/srep31040 [QUOTE] [...] a recent preliminary study of Mesolithic and Early Neolithic human remains (Crèvecoeur 2012) [b]describes strong and signifcant diferences (anatomical discontinuity) between the two populations from el-Barga (in the Kerma area).[/b] The Mesolithic group is more similar in terms of body size and robustness to the groups at Jebel Sahaba, Taforalt and Wadi Halfa (Crèvecoeur 2012, p. 28). Moreover, the genetic or anatomic discontinuity between the late Pleistocene population of Jebel Sahaba and that of the Gebel Ramlah Final Neolithic (following the Wendorf terminology) [b]implies that ‘replacement or genetic swamping of an existing gene pool by an outside group, or groups, occurred after the Pleistocene’ (Irish 2005, p. 520). If this suggestion is correct, we anticipate that this discontinuity occurred near the end of the 7th millennium cal BC and that it is linked to the arrival of small agro-pastoral groups from the Levant[/b] (Bar-Yosef 2013, p. 244), apparently in connection with the so-called 8200 BP climate crisis, as suggested on genetic grounds (Smith, A.C. 2013). [/QUOTE]Salvatori et al., The neolithic and "pastoralism" along the Nile : a dissenting view, 2019 [QUOTE]Specifically, [b]he suspected that population replacement or genetic swamping occurred in Nubia sometime in the early Holocene (Irish, 2005). The current results are in agreement with this finding[/b] , with one subtle distinction. [b]The current body shape results seem to place the time of the genetic discontinuity to a period subsequent to the mid-Holocene (i.e. after 4000 years ago),as opposed to the early Holocene.[/b] [/QUOTE]T.W.
