Apologies, I only meant my gripe with the comment I was responding to. Is why I put "as stated." I meant that to be that I was not arguing what I think they were messaging towards.

The callout on "evidence" I have there is that I meant that to only be present evidence. And again, I am not convinced it can't be done. It takes a lot of work. Which, the article is doing. But just saying that traits that helped you survive are typically retained, so by definition increase fitness, does not.
