Eventually, they amassed a collection of almost every one of Lake Tanganyika’s 240 cichlid species, including dozens that had not been described previously.

The researchers suggested that if there is more hybridization within branches of cichlids than between the branches, it could cause the disparity, although it wasn’t clear from the data that this occurred.

Africa’s deepest freshwater lake holds a dizzying array of animals, including hundreds of species of cichlid fish found nowhere else in the world.

Surprisingly, when the researchers examined their cichlid data, both models seemed to be relevant.
