This argument seems like something I would need to think long and hard about, which I see as a good thing: it seems rare to me that non-trivial things are simple and apparent. I don't see any glaring misinterpretation of natural selection. I would be interested in working on it in a "dialogue intellectually and hammer out more complete and concrete ideas" sense. I'm answering this quickly in a tired state because I'm not on LW as much as I used to be and I don't want to forget.

I'm getting a PhD in a biological field that is not Evolution. Both this and my undergraduate education covered evolution because it underlies all the biological fields. I have one publication out that discusses evolution but is not actually specifically relevant to this topic. I'll happily share more detail in private communications if you can't find an explicitly evolutionary biologist.
