For me to argue further would be to argue the meaning of “failure” in this context, when I’m pretty sure I actually agree with you on all of the substance of our posts.
I really do not want to argue about semantics either, but our agreed interpretation makes Niel’s statement equivalent to “our visual system is not optimal for non-ancestral environments”, which is highly uninteresting. I think the Dawkin’s larengyal nerve example is much more interesting in this sense, since it points out body designs do not come from a sane Creator, at least in some instances (which is enough for his point).
Since we do not live in the ancestral environment now, I think the quotation could be just underlining how we should viscerally know our brain is going to output sub-optimal crud given certain inputs. Upvoted original.
