Here you will find resources to help educators and their students understand that many different plants and animals evolved and became extinct during the Phanerozoic; recognize that plant and animal fossil assemblages of the very deep geologic past are unlike organisms alive today; describe the variety of plants and animals that once lived in your community; relate the increases and decreases in the numbers of different organisms during the Phanerozoic to geologic causes; describe several lines of fossil evidence to support the theory of evolution based on the fossil record.

Here you will find resources to help educators and their students understand how changes in the Earth's climate have affected organisms throughout geologic time; understand that organisms that dominate the continents today differ from the organisms that dominated the Earth in the deep geologic past; understand that severe ecological disruptions alter the history of life, resulting in extinction followed by the evolution and appearance of new organisms; understand that newly evolved organisms develop similar body features that allow them to use the same resources as those organisms that became extinct.
