[QUOTE]Originally posted by Swenet: [QB] This is why you don't mix autosomal split times with haplogroup dates, and why split times usually aren't historical. Populations split and then meet each other again, making most autosome-derived split times conflations of actual split times and admixture events: [QUOTE] In this study, we focus on two aspects of African population genetics, 1. the nature of population structure in Africa going back in time and 2. the timing of the Out-of-Africa event. To address these questions, we assembled a dataset with whole genome sequences from 162 individuals using both in-house sequencing and publicly available sources. These samples span 22 populations worldwide. These include eleven African populations which we use to dissect the population substructure in Africa. In addition, we also have 2 Middle Eastern, 5 European and 4 East/Central Asian populations which inform the population split time estimates for the Out-of-Africa event and the European-Asian split. We [b]find extensive population structure in Africa extending back to before the Out-of-Africa event[/b]. The Ethiopian populations, [b]Amhara and Oromo, show evidence of mixing beyond 15 kya[/b]. The [b]Maasai and Luhye merge with the Ethiopian populations to form a panmictic East African population ~40kya[/b]. We find evidence for [b]extensive mixing between east and west African populations before 50kya[/b]. Among the pygmy populations, we see recent gene flow between the Batwa and Mbuti. [b]All African populations except the San merge into a single population around 110 kya[/b]. The San exchange migrants with the other African populations beginning ~120 kya. We estimate the Out-of-Africa event to have occurred ~75kya and the European-Asian split to ~25kya.[/QUOTE] http://www.ashg.org/2013meeting/abstracts/fulltext/f130123045.htm As far as applying this to the 80ky admixture date of BE... we don't know when BE actually split, since BE is likely a mixture, like all other populations. And how does one give a mixed population a single split date, when it consists of two or more populations? Now watch elMaestro casually post something to this effect a month from now, like he wasn't vehemently arguing against this. You just can't make up what these people do online. Pure entertainment.
