Thanks for that. I notice the full article is in Russian.
“moms and dads change the methylation pattern of the DNA they pass down to enhance their own particular reproductive strategies”
Certainly something like this must have happened in a very small population under severe selection pressure (like Berengia).
We don't know much about the epigenetic differences between human populations. There has yet to be an “epi”Genome project. But there really isn't that much difference between humans. If there was an appreciable difference in epigenetic sexual differences then reciprocal crosses between populations would be different (i.e. a child of a male Amerindian and a female European would be different than the child of a male European and a female Amerindian). I don't believe there is any evidence that this is the case, and neither is there really a reason to suspect it.
