How can we then believe previous admixture age estimate based on this method?<br /><br />Why are the admixture percentages found here so low (e.g., 1% Neanderthal in W Europeans, <1% Denisovans in Oceanians?<br /><br />I find Fig. 3 intriguing - especially the "desert" regions.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-52106645975594508282016-04-01T00:33:01.249+03:002016-04-01T00:33:01.249+03:00Extremely interesting paper.
