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 ...

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 ...

No less than 500 new species of cichlids, brightly coloured perch-like fish, evolved in Lake Victoria (East Africa) over the past 15,000 years -- a record in the animal and plant world. This ...

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 ...
