Extinctions are as important in the history of life as are the evolution of new species. Explaining extinctions is just as challenging a scientific question as explaining the evolution of new species. AP Environmental Science. Mr. Grant. Lesson . 38. Objectives:.

Volcanic events. Ocean temperature change. Sea level changes. Meteorites. Glaciations. Global climate change. Competition/predation. Human causes of extinction/loss of biodiversity - HIPPO. Modern Extinctions. In the tropical Pacific, 154 species, mostly birds of large size, those that nested on the ground, and those that were flightless were the first casualties (Boyer 2008, 2009). In . The rise and fall of biodiversity. Four major mass extinctions of marine organisms:. End of Silurian Devonian, Permian, and Cretaceous). Rise in diversity during Cambrian, Silurian, Cretaceous, and Paleogene. Remember. Operant conditioning extinction differs from classical conditioning extinction. During extinction, responding decreases to baseline levels for both classical and operant conditioning. BUT: Operantly conditioned behavior shows:. Conditioning. Associative Learning.
