Evolution Through Time

In this video, you'll visit Learner.org and watch a video from a series called "Earth Revealed". The video you're about to watch is called "Evolution Through Time" (I think. I had to match the URL to the corresponding video on http://www.learner.org/resources/series78.html# -when you scroll down there is a list from 1-26, and when you click on one a separate window pops up. The "322" URL on the course outline that corresponds with the list is # 11- Evolution Through Time).
