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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

About this issue Abstract Phylogenetic analyses based on mitochondrial (mt) DNA have indicated that the cichlid species flock of the Lake Victoria region is derived from a single ancestral species ...
