I don’t accuse Turner of bad science. I have not read his book, so I can’t judge that. All I have said, is that I have not been persuaded that his book is worth my time.
I can’t really judge whether Shapiro is a nut. From my perspective, the main issue is that he overstates what he has. I actually see it as a good thing to be talking about intelligence in the cell, but best to not overstate it.
That’s how it seems to me.
If I think back to 25 years ago, where I was following discussions on usenet, it was more Darwinist than what I see now. Larry Moran was favoring neutral evolution, but not many others were. It seems to me that a lot has changed over the last 25 years. There has been a move away from selection. What the “Third Way” wanted to accomplish is happening anyway. That’s why it is irrelevant.
As for teleology, we have had some discussion here in the topic Do heat seeking missiles have teleology, and it quickly became clear that people disagree about what teleology is. So avoiding the term is probably still wise practice for scientists.
