Ask most men or women in the street who Charles Darwin was and the chances are that they will know something of the work he did: the work that has revolutionised our understanding of the living world and our place in it. The 200th centenary of his birth was in February 2009. Over the 150 years since the publication of his seminal work On the Origin of Species by means of Natural Selection, the quality of his scientific thinking, experimenting and writing--leading to the formulation of his ideas about evolution--has had the single most profound impact on the development of modern biology. During this year a number of dedicated Darwin websites have been created and this edition of Webwatch describes a small number of the best of them.
