Fish in Africa have become record-breakers for the speed at which new species emerge

Among them, the experts singled out intensive sexual selection, acting as a “catalyst” of evolution, in addition, these fish have jaws that are easily rearranged for different types of food during evolution, as well as they are characterised by interspecific interbreeding, which allows you to create more survivable hybrids hybrids.

The researchers emphasised that these factors are also characteristic of other fish, but it was their combination that allowed cichlids to create so many species.
