go here to watch or re-watch PBS (Nova) videos on evolution and to help you answer the questions on your study guide.

Here's another copy of the study guide ( for anyone absent or anyone who lost it), you will have to turn in your completed study guide, as well as your completed window panes on Friday prior to your test.
Nova:
