The patterns of differences and similarities of eyes within and between groups of animals show EXACTLY THE SAME patterns of differences and similarities that we see when we group them based on other anatomical features.
We see the same nested hierarchies when we group them based on many different features.
Nicely said. This (and not the mere existence of diversity) is an argument for the theory of evolution.
An informed creationist might have done a better job of arguing that the nesting is a result of God's will in creating those animals. Of course, other evidence, such as the fossil record suggests that God did not actually create all of those animals at a single point in time, which kind of makes the effort not worthwhile (IMO).
Robert's arguments missed the mark because in many cases he did not know what animals have what kinds of eyes before he heard it here, and because he could believed he could predict what kind of eyes God would give creatures with some rather simplistic rules. He failed miserably, and his peers seem content to watch him go down in flames.
