A special supplement to the June 16, 2009, issue of Proceedings of the National Academy of Sciences entitled "In the light of evolution III: Two centuries of Darwin" is now freely available. As the editors, John C. Avise and Francisco J. Ayala, explain in their introduction:
In the articles of this Colloquium, leading evolutionary biologists and science historians reflect on and commemorate the Darwinian Revolution. The authors of these Proceedings canvass modern research approaches and current scientific thought on each of the 3 main categories of selection (natural, artificial, and sexual) that Darwin addressed during his career. Although his legacy is associated primarily with the illumination of natural selection in The Origin, Darwin also contemplated and wrote extensively about what we would now term artificial selection and sexual selection, as reflected for example in two books titled, respectively, The Variation of Animals and Plants Under Domestication (1869) and The Descent of Man and Selection in Relation to Sex (1871). In a concluding section of these Proceedings, several science historians comment on Darwin's seminal contributions. Thus, these Proceedings are organized in 4 parts: Natural Selection, or Adaptation to Nature; Artificial Selection, or Adaptation to Human Demands; Sexual Selection, or Adaptation to Mating Demands; and The Darwinian Legacy, 150 Years Later.
Among the authors represented are NCSE Supporters Francisco J. Ayala, Michael Ruse, and Elliott Sober. Recordings of and slides from a few of the talks are also freely available.
