Khoisans Are Genetically Admixed and Not Basal to Other Humans, Hadza Are Recently Admixed
In my last post I discussed the ways in which phylogenetic trees constructed on the basis of genetic data confound population relationships derived from common descent and from admixture. Unless admixture is taken into account, the sampled populations may end…
How to Interpret Patterns of Genetic Variation? Admixture, Divergence, Inbreeding, Cousin Marriage
Two different but important population genetics papers have come out. One is Steven Bray et al. (2010) “Signatures of Founder Effects, Admixture, and Selection in the Ashkenazi Jewish Population.” The other one is Isabel Alves et al. (2012) “Genomic Data…
Howler Monkeys, Neandertals, Pygmies, Khoisans and More: Society for Molecular Biology and Evolution 2012
As I write, Society for Molecular Biology and Evolution (SMBE) is conducting its annual meetings in Dublin, Ireland. Dienekes has many useful pullouts from the available abstracts. I will make short comments on a few of them, plus bring in…
