>In the second half of the 20th century, it was becoming ever clearer that our unique evolutionary history was responsible for many aspects of our unique human psychology
In my experience, most "evolutionary psychology" stories are also ad hoc, unfalsifiable at best, and loaded with cultural biases from those who propose them. We don't have a good idea of what traits actually carry a selective advantage, and those advantages are often highly context dependent. The brain, culture, and evolution are both incredibly complex, and so you can often find some way to smush puzzle pieces together that almost works, but that doesn't mean that's what's actually happening.
A lot of traits and variances have no clear evolutionary advantage, most of the time it's fudging and trying to come up with an explanation for a certain behaviour
There aren't good evolutionary explanations for a lot of physical traits, let alone for psychological ones
