> I've more or less given up following all the posts that DT makes that give links to work on biology and evolution, since they are mostly perfectly valid work-in-progress. Inevitably there are many alternative hypotheses put forward, and rival research teams enthuse over their own ideas. This is the way science is done these days. Eventually as more evidence is accumulated a clearer picture will emerge.-Part of the problem you describe is the sensationalism required in today's newsmongers. With TV, print papers, and 24-hour news channels and the internet blogs, etc. everyone is vying to sell their story. Remember the IDA fossil hysteria. I post these findings because I have time to hunt them up and I think many of them do provoke discussion.

I would have thought the sounds that animals make could quite easily evolve gradually, and their ears likewise. -You are making the Darwinian assumption of gradualism in development. If you note my other recent entry, there is much less gradualism than originally proposed. In that view their argument has a point.
