PPT-Modern extinction

The sixth m ass e xtinction Objectives Define extinction Give examples of 1 past mass extinctions 2 and recent species extinctions Compare current extinction rates with background extinction . Overview. 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:.
