Fish, be advised. John Davison is a class A loony. I don't mean I disagree with his gobbledygook. I mean the man is crazy. Even the creos kicked him off their sties. Google him if you doubt me.
Pierre Grasse died 23 years ago. I wouldn't accept a paper at face value if it was 23 years old. (There are exceptions, of course. Einstein's 1905 paper on Brownian motion, for example.) Much less the opinions of a a "biologist" that said:
No matter how numerous they may be, mutations do not produce any kind of evolution.

I have no idea who "Goldschmidt" and "Broom" are. Pretty tough to google too.
