Saying, "I think it's extremely unlikely" does not amount to "refuting".| Quote | | What random mutations have we observed that were useful? |
I don't know about you, but I've observed many virus mutations that allow a virus to better cope with different hosts, different metabolic conditions, particular drugs, particular antibodies... happens all the time. If it didn't, drug resistance in HIV wouldn't be a problem. | Quote | | How do small mutations leading to better sight also manage to randomly mutate the needed nerve pathways and brain and skull reformations? |
Are you being quite serious here? Evolution is an iterative process. Mutations build on one another. If one mutation leads to better vision, that presumably is beneficial in and of itself. Subsequent mutations leading to more brain development capable of using the better vision then become favorable, etc. Also, did you know that skull formation is responsive to brain formation? There are in fact mutations that result in severely limited brain development (microcephaly). Guess what! In those cases, you don't develop a normal skull with a tiny brain rattling around in it; the skull forms during fetal development in response to the forming brain.

It demonstrates the one system is almost certainly related to the other by the process of "co-option" that Behe has "refuted" by declaring it unlikely. (Personally, I don't have an opinion about which, if either, is more "primitive"; I suspect they both evolved from a still less complex system. But the point stands: an evolving system can have a series of selectable functions without the "final" function being selected from the very beginning.)
By the way: you forgot to point out where I called Spetner "malicious".
