You're going to need to be clear on what you're asking. What is covered by 'mind?' Cognitive abilities & psychological traits or no?

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.
-
it’s because some traits emerge as by-products of others that appeals to natural selection are vacuous
-
That's simplistic. We just have to say that we can't always be sure something is adaptive & not a by-product of something else
-
See. Conversation works much better when you say what you mean clearly in whole sentences.

The evidence that our brains have adapted is the evidence that our brains have evolved and evolution works by natural selection.
-
But whether a specific cognitive ability or psychological trait is an adaptation or by-product of something else is less certain.
