You can go to any junkyard and dig up the fossil-equivilents of species after species of automobiles, too, but that doesn't mean that cars evolved themselves from one model to the next.
The only theory that accurately explains different automobile model "fossils" is that of Intelligent Intervention, as in, Man made the models different, even though some of the "transitions" between models are occassionaly very subtle.
"Evolution".
From the man who said, "History is bunk."
