Dinosaur extinction at peak diversity supports Raup's hypothesis

By scientific and blogospheric standards, this item is ancient news. But it is sufficiently interesting to warrant recording for later use. The spectacular extinction of the dinosaurs at the K-T boundary evidently occurred at peak diversity. This finding strongly supports David Raup, who has long argued that extinction is more a matter of bad luck than of bad genes. The implications for contemporary biodiversity policy should be self-evident.
