Neil Shubin Talks Tiktaalik

If you're interested in vertebrate paleontology in general (and the evolution of the first tetrapods in particular) then you might want to take an hour out of your day and watch this lecture by Neil Shubin. In it, Dr. Shubin describes his research in the Canadian Arctic and the 2004 discovery of Tiktaalik roseae, a 375-million-year-old fossil that fits into an interesting gap in the fossil record between fish and terrestrial tetrapods.
