Trevor Stott Posted over 1 year ago As we are programmed to die after a certain period. I believe species are also programmed to die after a certain period. I just don't see any evidence for that, man. I think you're right in the sense that most species eventually die out--that is, eventually conditions change and the animal either evolves or goes extinct. But nobody's ever seen a species just "die out" for no reason...the species that do go extinct always go extinct because they're just not competing effectively anymore--and there's not many other species that can compete with homo sapiens. But how and why would the lifespan of a species be programmed? Evolution is what creates living things, and there's just no reason evolution would program a species to die out.
