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 ...

Researchers have found that chunks of "flipped" DNA can help fish quickly adapt to new habitats and evolve into new species, acting as evolutionary "superchargers." In the face of threats from other ...

Scuba divers found some “large”-eyed lake creatures off the coast of Malawi and discovered two new species, a study said and photos show. Photo from Getty / iStockphoto Plunging into a large lake in ...

Biologists have genetically mapped the sex chromosomes of several species of cichlid fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve. In research ...

Hidden within fish DNA are powerful genetic twists that may explain one of nature’s biggest mysteries: how new species form so quickly. In Lake Malawi, hundreds of cichlid fish species evolved at ...

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 ...
