- Abstract:
- Little is known about processes causing adaptive radiation, the fanning out of one species into a diversity of functional life forms. A central tenet of adaptive radiation theory, that resource competition is driving such divergence, makes predictions for the temporal relationship between species and morphological diversity that have rarely been tested. Replicate radiations of cichlid fish that evolved in several African lakes provide a unique opportunity to test it. Using molecular phylogenies and morphological data for all radiations, we ask whether morphological diversity and disparity continue to increase in the course of a radiation after species richness has plateaued, and whether deterministic processes dominate over stochastic events in determining trajectories of morphological evolution, as predicted if divergence is driven by competition.
