Periods of deep, clear water in Lake Malawi over the past 800,000 years coincide with bursts of species diversification, researchers show in a new report. Africa's Lake Malawi is home to hundreds of ...

Africa's Lake Victoria is home to one of evolution's greatest experiments. In its waters, what began as a single lineage belonging to the cichlid family of fishes has since given rise to a dazzling ...

The cichlid fishes of Lake Malawi are famously diverse. However, phylogenetic and population genetic studies of their history have been difficult because of the great amount of genetic variation that ...

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 from the ...

Despite the dramatic difference between day and nightlife, how fish exploit different times of day has not been studied systematically. Scientists explored alterations in the circadian timing of ...

Plunging into a large lake in the East African country of Malawi, divers scanned the rocky coast for aquatic life. Some “large”-eyed creatures caught their attention — and turned out to be two new ...
