There is a graph arguing “intelligence” has been positively selected in west Eurasian population in this paper according to a polygenic score (page 8 fig. 4)

Now I would be quite curious to know how they constructed this polygenic score

... because it's a study of West Eurasian DNA. The claim that humanity has over millennia selected for intelligence isn't all that spicy.

First yes it is. The claims that this time period was too short to meaningfully change phenotypes in human populations was not entirely far fetched.

Then to address the elephant in the room - which is the race discourse subtext let’s be honest - it’s highly unlikely that any recent selective pressure on a separated population, which resulted in meaningful phenotype adaptations, happened similarly everywhere at the same time
