Careful you almost misquoted me there

For the non-human animals, it certainly isn’t controversial to say evolution is the only explanation for the origin of behaviour. What else could it be?

there’s a lot to unpack here. firstly, there is more to human behavior than genetics/evolution, hence nature vs nurture.

It’s a jolly good thing I was talking about non-human animals then.

in other words our human experience determines our behavior in addition to genetics.

It’s a common fallacy to suppose that because an behavioural adaption has a genetic basis that therefore having the genes determines the behaviour.

Misconception #3 in the above.

Secondly, that’s not the only claim or assumption of Evolutionary Psychology. There is lots of other stuff besides that statement that is controversial at best.

Evolutionary Psychologists make claims, some of which yes are clearly lacking in explanatory power, evidence and predictions.

Yes I’m familiar with Wikipedia, if I’m just going to be talking to a search engine here I’m not terribly invested in continuing.
