from NatGeo last week was very good. Catch it if you can. Dramatized a bit of course, but interesting. Could have made it longer IMO. 2 hours with more detail would have been nice. Still, it shed some light on his journey around South America in the Beagle and how the ideas of common descent and natural selection slowly came to him. This of course did not all happen in the Galapagos, as many people seem to think.
