It usually takes millions of years for new species to evolve, but not for fish in one African lake.

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 ...

"It takes a village to raise a child" doesn't apply merely to humans. Many species of mammals, birds, fish, and various ...

The analysis of fossils in sediment cores from Lake Victoria, Africa, reveals that a group of cichlid fish rapidly diversified as the lake got larger and provided new ecological niches, whereas the ...

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’. Why are there so many different ...

Why are some species more likely to diversify than others? For the largest group of vertebrates, ray-finned fishes, the ability to evolve by transitioning back and forth between simple and complex ...
