Molecular Variance Across Genetic Systems in Modern Humans and Their Kinship Structures
Gisele Horvat has kindly pointed me to this new pre-print. This post is cross-posted at www.kinshipstudies.org. Global patterns of sex-biased migrations in humans Chuan-Chao Wang, Li Jin, Hui Li. Abstract A series of studies have revealed the among-population components of…

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…
Out-of-Africa in the Mid-Pleistocene: A New Interdisciplinary Paradigm or a New Myth?
In the comments section on this blog, Dienekes raises the issue of interdisciplinary support for the out-of-America theory. Since I’m a big proponent of interdisciplinarity, the seeming convergence of genetics, archeology and paleobiology on the origin of modern humans in…
Neanderthals and Amerindians: Intragroup Genetic Diversity and Population Size
John Hawks writes: “Neandertals have strikingly limited genetic variation. They once lived across a range from Spain to Siberia. Yet when we compare sequences across their whole genomes, we find them to be much less different across this geographic range…
