Description:Some people think dinosaurs became extinct because of a comet. If it was a comet, why is there still life on Earth? Maybe other species were immune to the comet's effects. However, I think they killed each other to extinction. Burger thinks they couldn't reproduce fast enough because maybe their females weren't friendly enough. He does have a point about female unfriendliness, but I doubt that extinction will ever happen to us humans! (It takes something very, very tragic to cause a species' extinction!)
