Africa's Lake Victoria is home to one of evolution's greatest experiments. In its waters, what began as a single lineage belonging to the cichlid family of fishes has since given rise to a dazzling ...

Mate preferences on male colour have been implicated in generating and maintaining species diversity among haplochromine cichlid fish. Their lek-like mating system suggests that not only male colour ...

Evolutionary innovations help animals cross functional barriers and exploit new niches that were inaccessible to their ancestors. These might even promote rapid diversification or reduce extinction ...

Evolutionary biologists are fascinated by how so many species of cichlid fishes have evolved in the Great Lakes of East Africa. It seems likely that visual cues played a key role in this explosive ...

Two new species of cichlid fish from Lake Victoria are described by biologists from Naturalis Biodiversity Center (Research Department Marine Zoology) and the Institute of Biology Leiden (Section ...

Pictured on the left is the Nile perch, a voracious predator introduced into Lake Victoria by humans to satisfy meat demands in the 1950s. On the right, several species of endemic cichlids that were ...
