Take 100 fat overweight Americans (50 male and 50 female), and dump them off on a deserted isle in the Pacific. Don't go back for 200 years. When you finally go back...the descendents of the 100 islanders will not be fat. They will be sleek slim islanders. Do I call this evolution? Not really...but some folks might. The same would occur with any animal or any plant that is taken from its normal place...and placed in different surroundings or different climate. Again, I would hate to use the word evolution, but things change. Did the dinosaurs evolve? While I can't prove anything...I can say point-blank they couldn't meet the requirements of existence...so they met their untimely end. Would I refer to this as evolution? No.
We have taken this word evolution and tried to make it fit a particular situation...and too many holes are left in it. But the word change does fit. In this simple world of ours, you either change or die...its the one common denominator of life on earth.
Actually, reality has already proven you wrong.
Take a few hundred Polynesians. Make sure they are large enough, fat enough to survive a grueling, several thousand miles paddling through the Equitorial doldrums without eating. Let them cast their lot on the Hawaiian shores for nearly a thousand years.
The Hawaiians are some of the largest, fattest, most obese people on the planet, as are the Samoans for the same reason. Their genetics determined their lot.
(!) - Hey, makes my day. Going beddy bye now. Examine that agency of change. Tell me that no species go extinct and this has no ramifications upon the future speciation of this planet.
Can humans go extinct? Oh, that's right. Non-replicable, invalid theory, not science.
