Approximately 65 million years ago, a large percentage of vegetables and animals suddenly became extinct. It was in the late Cretaceous period and there are various theories about it. Some scientists attribute this event to a gradual process that finally led to selective extinction. Others assert that a catastrophe, such as an asteroid hitting the Earth, caused these species mass extinction.
