Brian Switek has the 3rd edition of the new paleo-carnival The Boneyard up at his blog Laelaps. Besides links to a number of great stories on all aspects of paleontology, Brian has gathered a collection of some of the best blog reaction to the big cover story in the journal Nature, providing evidence that Homo habilis and Homo erectus lived at the same time. If you had any questions about that story, or about the media coverage of it, this is the place to go for answers.
