Asteroid Impacts May Have Boosted Evolution By Dave Mosher
December 18, 2007

The article stated in part:

“Space rocks are blamed for a lot of rough times on Earth,
from the die-off of most marine animals some 250 million
years ago to the disappearance of the dinosaurs 65 million
years in the past.

A new theory, however, suggests that catastrophic meteorite
impacts are linked to an explosion in biodiversity about 470
million years ago, during the Ordovician Period.”
