On an eco-tourist cruise to the Galapagos aboard the Santa Cruz, Richard Dawkins delivers several lectures on population genetics and the evolutionary process. Having read several of his books and watched most of his documentaries, I assumed I had just about exhausted his educational potential. This lecture series showed me the fallacy of this assumption. These are some of the best lectures I have heard on the subject, beautifully delivered as always by the eloquent professor. Available at Demonoid. Some lectures available at Google Video.
