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 ...

Lake Tanganyika in Africa is a true hotspot of organismal diversity. Approximately 240 species of cichlid fishes have evolved in this lake in less than 10 million years. A research team has ...

The unique diversity of cichlids in Africa’s oldest lake could help unlock the secrets of evolution. Baby Haplotaxodon microlepis scramble for safety in their mother’s mouth. Like many cichlid species ...

Researchers have developed an integrative approach to the classification of fossil cichlids and have identified the oldest known member of the tribe Oreochromini. Cichlids (Cichlidae) are a group of ...

Evolution, Vol. 73, No. 10 (OCTOBER 2019), pp. 2072-2084 (13 pages) Understanding the origins of biodiversity demands consideration of both extrinsic (e.g., ecological opportunity) and intrinsic (e.g.

There are more than 500 cichlid species in Africa's Lake Malawi. They evolved from a few species that likely entered the lake about 3 million years ago and now display very different behaviors and ...

The African cichlid fish radiations are the most diverse extant animal radiations and provide a unique system to test predictions of speciation and adaptive radiation theory. The past few years have ...

Adaptive radiations are iconic systems for the study of evolutionary processes because they generate a wealth of ecological and species diversity, often on very rapid timescales 2,4. Some of the most ...

About 1800 years ago, a volcano in northern Nicaragua exploded. The crater formed by the eruption slowly filled like a rain barrel. Eventually the water rose high enough to warrant the title of lake.
