Evolutionary biologists describe a new gene in the Central American Midas cichlid fish and identify a variant caused by a 'jumping gene' (transposon). This variant of the 'goldentouch gene' is most ...

All he touched turned to gold, according to the legend of King Midas from Greek mythology. All Midas cichlids from Central America start out life as black-and-white striped fish and then some of them ...

If one would rewind the tape of life, would evolution result in the same outcome? An evolutionary biologist came up with this famous question. He suggested that evolution would not repeat itself: the ...

Cichlid fishes are one of the best model system for the study of evolution of the species. Inspired by them, in this paper we simulated the splitting of a single species into two separate ones via ...

The mechanisms by which new species arise are still not fully understood. What are the evolutionary processes that drive the evolution of new species? Evolutionary biologists traditionally assumed ...

The Bureau of Fisheries and Aquatic Resources (BFAR) and the San Pablo City Agriculture Office have clarified that the fish ...
