Vail - A theory of power - No more biological evolution?

Additionally, agriculture virtually ended biological evolution for humans.
There remain a few, very minor exceptions, such as the improved lactose tolerance of Northern Europeans that probably developed alongside pastoralism and agriculture,

but evolution in general has switched from individual selection to group selection. While, in agricultural societies, some individuals would not live to reproduce, this resulted increasingly less often from lower individual fitness.

Instead, if the group prospered, far more members survived, regardless of individual
fitness. With the end of biological evolution, the makeup of our genome froze in the Pleistocene era of hunter-gatherers.
