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 ...

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 ...

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 ...

Lake Victoria cichlids are known to use differing chromophore mixtures (van d er Meer and Bowmaker, 1995). However, the new study of Terai et al (2002) is one of the first to examine the variability ...

If you liked this story, share it with other people. It might be surprising to learn that, in a lake as large as Victoria, a single fish could shape so much of East Africa’s history, culture and, now, ...

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 ...
