I don't agree with this point, for the following reasons:
(1) There ain't no such thing as "Science" having an opinion on anything, there are only opinions held by individual scientists.
(2) It is not the basis of most biological sciences. Genetics, physiology, ecology -- those are the basis for the biological sciences. If the TOE didn't exist the biological sciences wouldn't even notice. The only thing that is really dependent on TOE is threads like this one.
This is patently false. Let me tell you that nothing would make much sense in biology if it wasn't tied together by evolution, and yes working biologists put the theory to use on a very regular basis.
All the biologists that I work with (and have worked with in the past) disagree with you. There are many journals devoted to evolutionary theory. I suggest that you peruse a good univerity library's collection of biology journals and check the number of articles on evolutionary theory.
