Casual Friday — Transitional Fossils videos

For today’s video viewing, I thought I’d pass along a couple of really good videos that I found on Afarensis (but which were previously highlighted by The Panda’s Thumb). Confused by what it means for something to be a “transitional fossil?” Watch these two (total run time of about 18 minutes), and you should have a good handle on things.
