This is relevant and has interesting things for the students to do, thank you. Do you perhaps remember which Christmas lecture as the link now goes to a general page?

Sorry - Don't often look at this page the Christmas lecture is called the 300 million year war from 2009 and the clip is from lecture 1. It starts about 27 mins in and lasts about 5 minutes.
