Africa's Lake Malawi is home to hundreds of species of cichlids, the freshwater fish whose broad array of colors make them popular denizens of household aquariums. A new study shows how dramatic ...

CT scanning—which combines a series of X-ray images taken from different angles around an organism and uses computer processing to create cross-sectional images of its bones, is providing new insight ...

Ryan York from Stanford University has looked at the various courtship rituals of cichlid fish at different depths in Lake Malawi. His findings, published in the journal Frontiers in Ecology and ...

A new study shows that courtship rituals evolve exceptionally fast among cichlid fish in Lake Malawi. Only in shallow waters where the light is good, males attract females by building sand castles.

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 ...

Sex-determining systems may evolve rapidly and contribute to lineage diversification. In fact, recent work has suggested an integral role of sex chromosome evolution in models of speciation. We use ...

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 ...
