Magnitude and Overview of Global Biodiversity Loss:  Magnitude and Overview of Global Biodiversity Loss By Jeffrey A. McNeely Chief Scientist IUCN – The World Conservation Union [email protected] Presented to Biodiversity and Agriculture Symposium Punta Cana, Dominican Republic 31 May 2006 Ancient extinctions:  Ancient extinctions Ordovician: 450 million years ago. Some animal groups lose half their species. Devonian: 374 million years ago. Up to 70% of all species disappear. Permian: 251 million years ago. 95% of all marine life and 70% of land animals become extinct. Triassic: 201 million years ago. Up to a quarter of all life dies. Cretaceous: 65 million years ago. 85% of all species are wiped out, including the dinosaurs. Slide3:  These ancient These ancient extinctions were caused by natural phenomena For the next 60 million years, diverse forms of life populated our planet:  For the next 60 million years, diverse forms of life populated our planet Slide5:  Our early ancestors were part of the African savanna ecosystem.
