The spectacular radiation of 2,000 species of cichlid fishes in East Africa is an ideal model system and natural laboratory for studying evolutionary processes. The explosive speciation of cichlids is ...

Biologists use the term adaptive radiation to describe a phenomenon in which new species rapidly evolve from an ancestral species, often in response to changes in the local environment that lead to ...

New genetic analyses of cichlids in Lake Victoria highlight several candidate genes that may drive adaptive radiation and provide evidence for decisive selective events that cause particular genetic ...

The poster child for evolution may have finally revealed its secret. More than 1000 closely related but different species of cichlid fish live in Lake Malawi in south-east Africa – more than in any ...

Africa’s deepest freshwater lake holds a dizzying array of animals, including hundreds of species of cichlid fish found nowhere else in the world. They crowd the waters of Lake Tanganyika, with scales ...

Cuckoo catfish may be the worst parents ever. Rather than raising their own cannibalistic offspring, they force other fish species to raise them in their own mouths. But how do they do it? New ...
