4th video. Because he was obviously misrepresenting his opposition. Particularly on molecular genetics, and his dumb quote. Also "epigenetics"

1st R/k is debatable. But not like this. He didnt even know r/k was a thing outside of blogs, and that the originator E.O. Wilson approved of applying it to humans

2nd where he bungled species and subspecies, no point either

3rd. Find the genes is a novel evasion still.

It's clearly just a vendetta. Hence why he casts aside all quantiative genetics and quantitative social science. Literally anti-science because he can evade the issue by going into molecular genetics which is too young to affirm or deny this issue.
