Hear Duke evolutionary biologist Mohamed Noor discuss the work that made him one of only a dozen scientists honored with the Darwin-Wallace Medal in 2008. This prize is given only once every fifty years to those twelve scientists who have done the most to advance Darwin's thinking. Although Darwin's book title suggested that he provided us with insights on the origin of species, in fact, he only focused on the process of divergence within species and assumed the same process "eventually" led to something that could be called a new species. This event was taped live as part of the Periodic Tables: Durham's Science Cafe series at the Broad Street Cafe. Periodic Tables is a Museum of Life and Science program.
