A documentary programme called The Genius of Charles Darwin: Presented by Richard Dawkins is airing in the UK television station Channel 4. There is google video of episode one available over at Pharyngula in one part.
Or you can head over to the home of the man himself and watch it in five YouTube parts, or even download a Quicktime video (146MB) here. Richard has even provided a link to a torrent of the episode for download.
It's the first of a three part series. Richard does fine work with his documentaries, and the standard of this one is certainly on par with his previous films. Evolution presented in such an easy and understandable manner. I very much look forward to the next two episodes.
