[QUOTE]Originally posted by capra: [QB] [QUOTE]Originally posted by Swenet: [qb]Not just because they failed to find a Eurasian admixture event (which is very interesting in that it cautions against baseless backmigration claims), but because it shows that a lot of these papers lack holistic analysis. The branch leading to E-M78 is only 19ky old and this Taforalt sample is 15ky old. So admixture must have happened in that interval of 4000 years (19-15ky). The admixture was probably closer to 15ky than 19ky ago, too. Sometimes all these researchers need is common sense, not high-tech tools and software. [/qb][/QUOTE]an alternative common sense interpretation would be that Swenet is wrong about E-M78. :) or if admixture is required, that it occurred between populations which were autosomally fairly similar to begin with. i don't think the LD test would pick that up. so what Elmaestro said, though i'm not sure how powerful these methods are with low coverage ancient genomes and lots of population drift. PS according to a couple of sources this is pre-E-M78 with about 20% or 25% of M78 equivalent SNPs negative. given the uncertainty in TMRCAs it could have split from the ancestors of modern E-M78 a couple thousand years earlier, or ancestral E-M78 could have been next door. more likely the former.
