This course is offered through the Osher Lifelong Learning Institute (OLLI) at Colorado State University. You must be a member of Osher to enroll in this course.

In this journey through the last 541 million years of Earth history, we will examine the co-evolution of the lithosphere, atmosphere and biosphere. We will reconstruct the formation and breakup of super continents, the formation of mountain ranges, flooding and emergence of land areas and the warming and cooling of climates. We will also examine the evolution of life from the explosion of marine invertebrate organisms with shells to the invasion of land by plants and animals, the origin and extinction of dinosaurs and the evolution of mammals and humans.

The course is designed for those with an interest in geologic processes and history, including biological evolution.

Noncredit courses do not produce academic credit nor appear on a Colorado State University academic transcript.
