Lightning-Fast Evolution Clocked During Cambrian Explosion

A crustacean with 3,000 lenses in its eyes, 6-foot-long shrimplike creatures and organisms that looked like tulips emerged hastily (from an evolutionary perspective) on the scene some 520 million to 540 million years ago. And now scientists have figured out just how quickly evolution was occurring during evolution's "big bang."

And it was fast by most measures, five times quicker than occurs today.

"The abrupt appearance of dozens of animal groups during this time is arguably the most important evolutionary event after the origin of life," lead author Michael Lee of the University of Adelaide and the South Australian Museum said in a statement.

Still I wouldn't call a period of millions of years "lightning fast"

It just sounds better than "Molasses Fast"...
