Still evolving? Researchers from Princeton say that the Galapagos finches which provided Darwin with a striking example, are continuing to evolve noticeably. Some have said that while the finches may vary with local conditions, there is no true speciation, and the variation is therefore not a real example of evolution at all.

In other news, Darwin features in a series of stamps designed to celebrate the 150th anniversary of the National Portrait Gallery.
