Course Description:

The past 500 million years have encompassed a remarkable change in the third planet from the sun. In the cosmos, it is little more than a lightning flash of diversity. To us humans, it is a lineage over time too vast to assimilate. In this three-lecture series, geologist Ed Clifton examines the biological and environmental transformations that define the history of life on our planet, beginning with the explosion of diversity that initiated the Phanerozoic Eon and culminating with the global changes wrought in the world of today.
