About a month ago I posted quite a bit about Neandertal introgression into modern humans. That is, the uptake of Neandertal alleles are a few specific adaptively salient loci even while ancestry remains predominantly African. Now John Hawks and Gregory Cochran have a new paper out, Dynamics of Adaptive Introgression from Archaic to Modern Humans,…

Randall Parker has some comments on my neo-eugenics post.

Here is a summary of findings by a paper which suggests that the vast majority of genetic counselors tend to err on the side of protecting a mother’s privacy if her husband is not the father of her child. Here is an important point though: It is much more likely that bringing up the possibility…

P-eter comments on the Pakistani family which can’t feel pain. I remember in a genetics course once seeing the professor chart out a pedigree and calculate inbreeding coefficients and the expectation of the unmasking of deleterious alleles given certain matings. Now and then we would laugh nervously since of course real matings between individuals so…
