Phylogenetic relationships and evolutionary processes in East African cichlid fishes.

Since their discovery almost one hundred years ago, the adaptive radiations of cichlid fishes in the largest East African lakes have fascinated biologists. They are a prime example of explosive speciation. Among vertebrates, these species assemblages are the most species rich and the most diverse, morphologically, ecologically and behaviorally. Recent phylogenetic analyses of molecular data and refined knowledge about the geological history of the East African lakes are throwing new light on the evolutionary history of these extraordinary fish faunas.
