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 …

▪ Abstract Cichlid fishes (Perciformes: Teleostei) found in the lakes of Africa have served as
model systems for the study of evolution. The enormous number of species (1000 in Lake …
