Setting out to explore the evolution of these toothy variations, Peoples studied the teeth of 30,000 fish species, including 1,000 African cichlid species, for two years. Tracing their evolutionary ...

Fish can change their teeth quickly, which speeds up their evolution. Cichlids in African lakes show the fastest ...

The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that the ease with which these fish can develop a biological ...

They form new species more readily than any other group of vertebrates. Adaptations of the teeth and jaws that allow the fish to adapt to a wide range of food sources and habitats are thought to ...

Complex teeth with multiple cusps in an African cichlid fish. The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that ...
