this crap is not a joke. it's real. when the asteroid struck the Urth it caused a warble in the orbit. it cause the urth to lean backward, and then re-correct. the whole thingy took a whack, and adjustments were made. it brought on wintertime. cold, cold cold. dinosaurs don't do cold, right? enter the mammals, hairy, small, and plenty of fur & food.

evolution is with us. but so what?
