Asish Basu, Professor of Earth Sciences at University of Rochester has an article in the latest issue of the journal Science reporting that "An ancient meteorite body, one from the days when the solar system was still forming, struck the Earth 251 million years ago," This resulted in "The Great Dying" a period during which 90% of life on earth became extinct.

This created the environment in which the dinosaurs could rise to ascendancy. They in turn were driven to extinction 65 million years ago by a meteorite colliding with the earth making way for the ascendance of the mammals.

Hmmm, I detect a bit of a pattern developing here.
