appeals to natural selection don't explain which of two co-extensive traits is an adaptation and which is a by-product of adaptation

What do you mean by this? I'm sure you could explain clearly if you wanted to. Think about why you don't want to.

If you're just claiming that some traits emerge as by-products of others, of course. Cats probably fear cucumbers coz useful re: snakes.

But this is the same hypothesis that human cognitive abilities and psychological traits evolved. It doesn't come from anything outside it.

the claim that human cognitive traits and abilities evolved as adaptations (not by-products) is ad-hoc unless there's independent evidence

By-products of what? You accept that the brain evolved & that this is by natural selection so you accept that some of it is adaptive.

by-products of any co-extensive trait - it doesn't follow from the fact that i accept the brain evolved that i accept some of it is adaptive

It does if you accept that evolution works by what makes us survive & procreate & that many of those things are cognitive & psychological.

Our ability to recognise the opposite sex. Our instinct to nurture our children. Our instinct to run from danger

our ability to recognize the opposite sex is evidence that the mind is adapted?
