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.

From the origin of life on Earth 3.8 billion years ago to naked metazoans and the Cambrian Explosion to the colonization of land by plants and animals to the near extermination of Earth life in the end-Permian crisis to the rise of ruling reptiles and dinosaurs, and, finally, to the path to domination by the mammals, we will explore the biology and paleontology of these milestones in earth history.

Class instruction will include when selected life groups arose and will explore their subsequent history, leading to the organisms we recognize today. Life’s evolution, endurance, and elaboration will be highlighted.

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