James is referring to me here, and summarizing what I’ve said to him privately. My private conversations with him are well summarized in this interview: Livestream: How I Changed My Mind on Evolution .
This is similar to the case that Larry Moran has been making at Sandwalk for years.
Looking over his quote, I think you are reading too much into it. He has not said that biologists stoped caring about mutation and natural selection. IN context, as well, he is acknowledging where the Dissent from Darwinism did not reflect current understanding in evolutionary science. Perhaps he could have been more precise, but this is just a podcast, not a place where precision is expected.
