Scientists at the Shedd Aquarium have been successful in breeding a previously undiscovered species of fish that might help save Africa`s largest lake, Shedd officials announced last week. The fish ...

Fish will mate with a species outside their own if the male's colouring is attractive enough or if the female can't see him properly, according to new research. Such 'mistakes' in mate choice can lead ...

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 ...

Competition may play an important role during the evolution of new species, but empirical evidence for this is scarce, despite being implicit in Charles Darwin's work and support from theoretical ...

Scientists have uncovered evidence of fish mating with species different from their own—a process that can lead to the creation of several new species. For a study published in the journal Nature ...

Africa’s deepest freshwater lake holds a dizzying array of animals, including hundreds of species of cichlid fish found nowhere else in the world. They crowd the waters of Lake Tanganyika, with scales ...

The poster child for evolution may have finally revealed its secret. More than 1000 closely related but different species of cichlid fish live in Lake Malawi in south-east Africa – more than in any ...

Size differences among fish and competition for breeding space lead to the formation of new species, according to a new study, but empirical evidence for this is scarce, despite being implicit in ...

Female fish can breed a new species if they aren't choosy about who is Mr. Right. Fish will mate with a species outside their own if the male's coloring is attractive enough or if the female can't see ...
