### I am an amateur in population genetics, my actual work was in
mitochondrial genetics and Parkinson's disease, so I would be poorly
equipped to work on substantiating the hypothesis.

While the idea that increased mobility in a population may trigger changes
in fitness related to improved mating distance occurred to me
independently, I would be surprised if nobody else among population
geneticists ever though about it before. It's kind of obvious once you
think about it. However, if the hypothesis has indeed never been published,
it might be the basis for an interesting research project, maybe even a PhD
thesis. If anybody here knows an aspiring young population geneticist, feel
free to forward my Yamnaya post to him/her.

I doubt that the hypothesis justifies jettisoning out-group hostility based
on different levels of genetic relatedness. After all you could interpret
it as saying that to have smart, strong and beautiful children you should
invade foreign lands, slaughter the local males, and take their women as
concubines, the Yamnaya way. Also, it might justify increased hostility to
anybody who is farther away than the OMD, on their way to speciation. I
would be very wary of speciation among cognitively generalist sentients,
that can only bring war to extinction of one of the species. Based on what
I know about interspecies conflict, the presence of multiple species in a
single ecological niche is unstable, and it leads inevitably to the
eradication of all but one of the species (assuming absence of refugia,
geographic discontinuity, etc.). Since the niche for general intelligence
if very large, it may be difficult for more than one cognitively general
species to exist in a single solar system.
