From fossil teeth to carbon traces of plants in the soil, scientists are looking at clues to how changes in climate may have influenced early human evolution in Africa. Researchers from around the world gathered for a symposium held recently at the Lamont-Doherty Earth Observatory. Watch the videos of their talks on the Earth Institute website.
The workshop, featuring Kenyan Richard Leakey, the Smithsonian’s Rick Potts and many others, was organized by Professor Peter deMenocal, a paleoclimatologist at Lamont-Doherty and chairman of the Department of Earth and Environmental Sciences at Columbia.
