        Lecture Details

        Principles of Evolution, Ecology and Behavior (EEB 122) The fossil record holds a lot of evolutionary information that cant be seen on shorter time scales, although the more recent fossil record is more complete. Among other things, the fossil record demonstrates that extinctions can open up ecological space for new speciation and radiation, and that life forms tend to begin small and evolve to be bigger over time. 0000 - Chapter 1.
