[QUOTE]Originally posted by Elmaestro: [QB] For starters, the study you posted has V88 and H1 @ ~7kya in the Fulani. [IMG]https://s1.postimg.cc/1avel7x89b/age_estimates_H1cb.png[/IMG][i] terminals 1-13 are Africans, 14 South Europe.[/i] Also peep, V68* (V2009) found in Cameroon, Moroccan Berbers [b]Sardinians and southern Italians[/b] (Trombetta 2015) from Bakeda 2013- [QUOTE][i]Others, like sub-haplogroup U5b1b [34], [b]sub-haplogroups H1 and H3 [20,35,36] and haplogroup V [37] seem to have reached North Africa from Iberia in a post-last glacial maximum expansion[/b]. In concordance, an ancient DNA study from Ibero-Maurusian bone remains from Taforalt in Morocco detected the presence of haplogroups U6, V, T and probably H, pointing to a Paleolithic genetic continuity in Northwest Africa [38]. Additionally, male lineages also provide support to a Paleolithic [b]Asia to Africa[/b] back migration [39] [b]with Holocene trans-Saharan spreads as testified by the haplogroup R-V88 distribution[/b] [40]. [b]Other lineages, E-M81 [26] and E- M78 [41], seem to be of North African origin with Paleolithic and Neolithic expansions that reached surrounding areas. The presence of these clades in southwestern Europe has been attributed to trans-Mediterranean contacts **without involving the Levant**[/b][/i][/QUOTE]I'm throwing this quote out here to give a little perspective... *notice how V88 is attributed to Near Eastern expansion during the Holocene!! realquick, here's chiang 2016 on Sardinian population history [QUOTE][i]We were able to confirm a number of major features of previous analyses: the differentiation of Sardinia from mainland populations, the presence of high Neolithic farmer ancestry in Sardinia, and the presence of a small amount of sub-Saharan African admixture. Further, our analyses provide more detail regarding the isolation between Sardinia and the mainland. Our analysis of cross- coalescent rates suggest [b]the population lineage ancestral to modern-day Sardinia was effectively isolated from the mainland European populations approximately 330 generations ago. This estimate should be treated with caution, but corresponds to approximately 9,900 years ago assuming a generation time of 30 years[/b] and mutation rate of 1.25x10-8 per basepair per generation[/i][/QUOTE]I mention that to point out the following... [IMG]https://s1.postimg.cc/1ap0w4ejkf/R-_V88.png[/IMG] -Schroeder 2015; using an ancient AfroCarribean, they were able to get a coalesced age of 8.5 kya for the V88 split between Sards and Africans. We can effectively predict a timespan for which a lot of these relatively "inexplicable" clades were shuffled between Africa and Southern Europe, anywhere between 9000 and 5000 years ago. And there is detectable substructure among the "Eurasian" contributions to Fulani though the Kulichova et al 2017 article you posted above glosses over this.(because their main concern was Eurasians tbh, particularly potential European genetic and cultural contributions and not the African populations themselves.. ¯\_(ツ)_/¯ ) ...Not to mention Habers dates for non African Admixture and V88. [QUOTE][i]" ~The number of samples is shown on each branch tip.We estimate that the Chadian R1b emerged 5,700–7,300 ya, whereas most European R1b haplogroups emerged 7,300–9,400 ya. [b]The African and Eurasian lineages coalesced 17,900–23,000 ya."[/b][/i][/QUOTE]^ His broad coalescent age is important because his model was going off the assumption that V88 was acquired from the near east. However what he unintentionally does is provide evidence for an [b][i]isolated[/i][/b] Eurasian branch being related to the African variety. Which we have evidence for. -[i]see above[/i]. -Sards split from Europeans prior to the Coalesced age of V88 in the latter populations -SSAfrican V88 coalesces with Sardinian V88 after the supposed Isolation. -North Africa is between SSA and Sardinia -European signatures are weak in SSA African populations, other than the handful of Fula(or any other Africans) which recent European or even North African ancestry. And we should all keep in mind the presence of ancient North African DNA now and how that keeps suggestions such as Bakeda's (quoted above) in check. [/QB][/QUOTE]
