@NLENTS thanks for picking up the conversation. Unfortunately, I am a bit swamped today. I’ll try and answer a bit if we can. When I have a moment, I will give brief overview of why I think it doesn’t work so well, and then reopen our thread on the design of the eye (Nathan Lents: Bad Design of the Eye?). I think this will be instructive as to why I think the argument ends up having some problems, in my view.
I also continue to reiterate that your angle on this is not idiosyncratic to you, and is probably the dominant view amoung biologists (not all the agreement you are getting on this thread). No one, especially not observers, should interpret this as a referendum on @NLENTS specifically. I am the outlier here, but I think I can also make my case coherently enough that you will at least understand where I am coming from.
