Thus, the observations are[b] suggestive that GREATER MIGRATION TO EUROPE FROM SUB-SAHARAN AFRICAN HAS BEEN A LONG-TERM PHENOMENON.[/b] Y-chromosome and mtDNA lineages are Read more: http://egyptsearchreloaded.proboards.com/thread/2537/mevoy-ancient-connection-africa-europe#ixzz56QmqaU6I [QUOTE]Originally posted by Elmaestro: [Q] [QUOTE]Originally posted by capra: [QUOTE][qb]Aside from what is cited below you can tell what is going on at K=3. They are using Khoisan to represent "Africans' not Mbuti or YRI. That is why some Khoi_San groups show no "Eurasian/European" admixture @K=2. That is a dead giveaway that we are looking at a supervised cluster chart.[/qb][/QUOTE]no dumbass that is what ADMIXTURE does unsupervised. the program is doing that because there are a lot of Khoisan in this particular run. ADMIXTURE runs aren't consistent, as would be fucking obvious if you ever actually thought about what you were seeing instead of skimming for something you can crop and paste [/QUOTE]^This, Skoglunds Admixture run basically reveal a gradient from Ju_Hoan to Sardinia (Neolithic Europe). Being that in the absene of YRI, the combination of heterogeneity and shared frequency within the Ju-Hoan gives the strongest likely hood for a singular population. Xyyman can show us another plot where the San HGs shows Eurasian signals at Low K... He used to spam that. However I was gonna let him rock for the fact that the argument can be made about Early African-San HG-like populations representing a later expansion into Europe. I've been messing with the Idea for a while that there might be [b]recent shared undetectable ancestry in SSA and west Eurasians.[/b] One of the few ways I find that achievable is if this mysterious population was relatively undifferentiated (from ancient founder) and [b]possibly ancestral to both West Eurasians and SSAs.[/b] http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=009649;p=2#000053 This is possibly seen in the ancient Moroccan DNA. who I speculate to have introgressed Ibermaurasian HG DNA. They lack SSA admixture related to any modern African population which would be detectable via Dstats or even genetic distance however behaves like an intermediate population to SSAs and Neolithic Europeans. The Idea that an Ancient population is made closer to SSA populations by mixing with Eurasians is fun to play with when looking at the Neolithic Moroccans. See the transition between IAM -> KEB.
