Cichlids are one of the largest and strangest groups of vertebrate fish — fish with backbones — on Earth. They’re popular as pets and farmed in aquaculture, and scientists have been studying them ...

Africa's Lake Victoria is home to one of evolution's greatest experiments. In its waters, what began as a single lineage belonging to the cichlid family of fishes has since given rise to a dazzling ...

Some female fish have eyes for their man only. Colourful African cichlids have evolved into new species because females are partially blind to others. But even as that discovery is made, the species ...

Sex-determining systems may evolve rapidly and contribute to lineage diversification. In fact, recent work has suggested an integral role of sex chromosome evolution in models of speciation. We use ...

African cichlid fish evolved in calm, clearwater lakes saturated with sunlight, and are known for their incredible visual system, which relies on a diverse array of visual pigment proteins called ...

Cichlid fishes have undergone a mind-boggling degree of speciation. New research is revealing features of their genomes that primed them to diversify so spectacularly Africa's Lake Victoria is home to ...
