Speciation song and screencast

The animated song and screencast videos are intended to be used together to give students an introduction to the processes that lead to speciation. It is intended for non-biology majors (eg. CSUN BIOL100) but may serve as a fun review for majors as well. After listening to the speciation song and the accompanying tutorial, students should: be familiar with the concept of gene pool isolation; appreciate that genetic variation is a prerequisite for evolution; be able to recognize examples of temporal, mechanical and behavioral isolation as well as gamete incompatibility and hybrid inviability/sterility; understand the difference between the Biological and Genealogical species concepts, and when each is used (the morphological species concept was not covered here).
