Humans are not fundamentally different from any other animal, with behavior and cognition largely shaped by selection for reproductive success.

This doesn't mean that all humans will behave the exact same, but human behavior is still overwhelmingly the result of evolutionary adaptation, and there are broad similarities, especially within each sex.

But whenever someone tries to bring up evolutionary biology/psychology into dating/sex discussions, many people, especially women seem repulsed and dismissive, resorting to empty platitudes like "everyone is unique", or "you'll find someone who likes you for you", or "we aren't cavemen anymore so people aren't/shouldn't act like them"(they greatly overestimate the typical rate of evolutionary change) or even "we aren't animals"(most cringeworthy).

For instance, women are horrified when men abandon their kids, but for the vast majority of human existence paternity was never certain. Unlike women, men didn't have the privilege of being confident in which kids are really theirs, so why would men have evolved to be as invested in children as women are? In most mammals, males don't participate in childrearing at all.
