Researchers: Cichlids are causing a rethink of the “fundamentals of evolution”

Researcher: Remarkably, this constraint seems to be the key to cichlid's success by promoting rapid shifts in jaw shapes and feeding ecology, all of which is likely to be an advantage in a dynamic and fluctuating environment, like the East African Rift Valley, where Lake Malawi is located. "The constraint is actually facilitating cichlid evolution, rather than impeding it," says Conith. Read More ›
