Evolution Through Time
This episode focused on what geology can tell us about the progression of life on Earth. It examined the study of fossils, both the actual remains of animals and the molds animals leave behind; chronicled efforts to explain the sudden extinction of dinosaurs; surveyed the vast wealth of fossils at the La Brea tar pits; and studied the implications on Darwin's theory of evolution.
