Newfound evidence reveals that the upsurge of the exotic Nile perch in Lake Victoria had long-lasting effects on the genetic diversity of various local cichlid species, report scientists from Tokyo ...

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 ...

B chromosomes have a functional effect on sex determination in a species of cichlid fishes from Lake Victoria, according to a study by Japanese researchers to be published in open-access journal PLoS ...

Multiple cycles of lineage fusion by hybridization and diversification led to increasingly rapid and extensive radiations of cichlid fishes, including the explosive evolution of 500 Lake Victoria ...

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 ...

The rapid evolution of Africa's Lake Victoria cichlids -- brightly colored, perch-like fish -- was facilitated by earlier hybridization between two distantly related cichlid species from the Upper ...

A once-threatened population of African fish is now providing a view of evolution in action. Laura Spinney asks what Lake Victoria cichlids have revealed about speciation. Ole Seehausen didn't expect ...

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 ...
