Ahhh, and this explains why trees developed bark, as a defense against millions of years of animals with partially developed eyes bumping into them.

Seriously, though, I am simply trying to point out that evolutionary theory shouldn't be accepted as fact when it leaves so much unexplained. I remember when it was a proven fact that dinosaurs were cold-blooded, and then it was a proven fact that they were primitive mammals and the latest proven fact seems to be that they were primitive birds (or has that changed?)

If the theory of gravity could explain how some objects fall, but couldn't explain how others do, I wouldn't accept it either.
