Can you see why that would be a problem for his inferences? I’m not going to spoon feed you the answers, you’re going to have to demonstrate that you’re willing to argue from a place of comprehension. I don’t care what you end up believing, but if you can’t correctly characterize the position of the critics of Axe’s work, this discussion is fruitless.
So before anything else, you need to demonstrate you understand what the issue is with Axe using a particularly temperature sensitive enzyme for his experiment (not that this is the only, nor even main thing at issue with his experiment and the conclusions he has drawn from it), and why we think his excuse there doesn’t actually work. Can you do that?
