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 ...

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 ...

Computed tomography -- 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, ...

Researchers have found that chunks of "flipped" DNA can help fish quickly adapt to new habitats and evolve into new species, acting as evolutionary "superchargers." CABI has published a "Guide to the ...

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 ...

Scuba divers found some “large”-eyed lake creatures off the coast of Malawi and discovered two new species, a study said and photos show. Photo from Getty / iStockphoto Plunging into a large lake in ...

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 ...

The Lake Victoria flock contains ten times less mtDNA variation than the Lake Malawi radiation, consistent with current estimates of the ages of the lakes. We present results of a phylogenetic ...
