摘要：

Analysis of adaptive radiation has had a central role in the development of evolutionary theory, but it is not clear why some groups radiate and others do not. Two recent papers by Albertson and colleagues on the genetic architecture of East African cichlid fishes implicate hybridization, transgressive segregation and genetic covariation in the early stages of adaptive radiation. Transgressive segregation and genetic covariation might be key innovations in genetic architecture that favor adaptive radiation.
