Simple, he is a well-known scientist. I've never heard that a sane scientist says "I don't believe in the theory of evolution", but that most(99.9...%) of biologists research under the paradigm of evolution. I know from my friends whose major are biology that Dockins is a extreme reductionist (<-- my favorite philosophical position) and when I read his books, I noticed my friends didn't tell a lie. Dockins had a kindness to provide me with a lot of models to simulate the evolution ('Selfish Gene' also has many models). All models can be simulated in workstation. As I know, KennyG is a computer scientist. Please try his model, and please let me know whether he is wrong or not.
