I believe you are incorrect. Every biologist on the planet does not buy into this theory, but you are correct that many do. As far as my own opinion, I think I have a pretty good handle on biology, at least enough to know that no biological proof of evoloution has ever been observed, documented, or recreated in a lab. Yes we can play with genes and select or reproduce certain traits like luminescent tobacco plants, mutated flies, or cloned animals. And I applaude all the research and real knowledge that is being gained from this. But no "improvement" or "evolution" has ever been observed or achieved, all mutations are detrimental in some way. Even if they yield a desirable trait, there is some detrimental effect. This is not "evolution", it is "selection". Natural or artificial selection and changes within a species are the only things that are observable, reproducable, or documented in any way. The rest of the "theory" is just that. A theory, which is propped up by a lot of incorrect assumptions and "evidence" that is proported as fact when it is not!
I could continue this discussion as long as you like, and back my opinion up with plenty of references, facts, and "real science",. My opinion comes from my own effort to answere some questions and a lot of my own thinking about those answeres. But I'm content to acknowledge that we will probably never agree and leave it at that. You can believe "540 million years" if you want, I don't. The reason I commented on it to begin with is this: I hope anyone who reads this thread will do some research of their own and come up with an original opinon instead of one that's been spoon fed to them by the so called "experts" who can print anything they like in a magazine, but can not back it up with real scientific facts!
