X-Message-Number: 28016 From: "JOSEPH W MORGAN" <> Subject: Mass Extinctions Date: Thu, 8 Jun 2006 14:41:06 -0700 In message 28011 Ron Havelock states "There is absolutely no solid evidence of mass extinctions." The geological and fossil record provides evidence for five major extinctions: 1.. Cretaceous-Tertiary extinction ~ 65 million years ago 2.. End Triassic extinction ~ 200 million years ago 3.. Permian-Triassic extinction ~ 251 million years ago 4.. Late Devonian extinction ~ 364 million years ago 5.. Ordovician-Silurian extinction ~ 439 million years ago Later, Havelock, contradicting himself, states" Without extinctions, sometimes mass extinctions, there would be no evolution."
