The question of which forces drivebiological diversity has challenged ecologists and evolutionary biologists for decades. In his Perspective, Erwin discusses an analysis of plants and arthropods in Hawaii and the Canary Islands by Emerson and Kolm, recently published in Nature. This suggests that species begat new species as community complexity increased. A similar process may explain the fossil record of diversity.
