Catastrophic Events in the History of Life: Toward a New Understanding of Mass Extinctions in the Fossil Record - Part I

Description:

Is extinction simply evolution’s way of destroying those life forms that fail to adapt to constantly changing environments? Does a species’ extinction reflect its failure to compete with the more sophisticated organisms with which it co-exists? Or, does extinction represent a random event; indiscriminately destroying lineages that otherwise could survive indefinitely? The best approach to answering such questions is to investigate episodes in the fossil record when rates of extinction have been phenomenally high: mass extinctions events.
