Dino Extinction Theory

One theory is that all of the dinosaurs were wiped out by a huge comet that came and hit the earth and killed all of them in one second. It is believed that if this did not happen then we would not have evolved or other animals. In the fossil record it is seen that the animals of the past are related to the animals of today. Some evidence shows that around a large crater there are particles from a meteorite that helps prove that there was a hit by a large rock that wiped out the dinos.
