course description
Course Description

Course Description: This course is an introduction to the study of evolutionary processes. We examine the basic mechanisms for evolution with particular attention paid to marine invertebrates, especially marine bivalves, as they have a rich evolutionary history and a well-documented fossil record. Evolution will be examined at a variety of scales from molecular to ecological.

Course Goals: Upon completion of the course students should be able to describe:

1. What evolution is and the evidence from marine invertebrates that support it

2. The major mechanisms of evolution

3. How scientists study evolution

4. How evolution is relevant to our lives
