The Making of Mass Extinctions
This interactive module explores the environmental factors and species involved in five major mass extinctions.
Extinction is a normal part of the evolutionary process. But during five periods in Earth’s history, extinction rates greatly exceeded normal levels. This Click & Learn allows students to compare these five major mass extinction events, examine each of their causes, and determine whether a sixth mass extinction is likely in the future.
