"Evolutionly"? Heheh...

Evolutionary biologists do not need to do drastic revisions, as science is cumulative (a bit like natural selection really). Ideas are constantly revised in the light of new evidence (unlike you, we accept evidence). There is no drastic lurching by the backroom boys to keep the show on the road. Once again you insult science and scientists from your standpoint of extreme ignorance. Of course,if you can demonstrate all this drastic change in thinking, I'll eat my words. But that's about as likely as a duff bottle of Hirondelle.
