Hmm, I doubt that. There still exist species of creatures that reproduce asexually, and they make off just fine. During asexual reproduction, new stemcells still get made, or something. At any rate the genetic material of the newborn isn't already aged like its parent.

It was definitely dinosaurs, of the type that walk on their hind legs and have a long ridge on their head. Fossils found of them showed deformations in the bones, and scientists deduced from that that the species got rooted out naturally. It was pretty strange.
