I had earlier posted only the clip about the tree of life. Now here is the full episode (about an hour long). It is actually quite well done (some good stuff on transitional fossils 28 minutes into the program), and its great to see video excerpts from David Attenborough's early documentaries (tip from Zakir Thaver). Overall, it provides a wonderful summary of Darwin and the way all species are connected together here on Earth - all in under one hour. Enjoy!
