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 ...
Lake Sampaloc in the Philippines is experiencing something of a gold rush because of an invasive species. The sight of golden-specked cichlids is increasingly common in the water after the fish — ...
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 ...
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 ...
Your fish are probably pissed off if you keep them in a small aquarium, suggests a study published this month in the Journal of Applied Animal Welfare Science that looked at levels of aggression in ...
Many species of fishes are aggressive when placed in small aquaria. Aggression can negatively affect the welfare of those individuals toward whom it is directed. Animals may behave aggressively 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." In the face of threats from other ...
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 ...
Sometimes individuals of the same species differ greatly in their shape or colouration. Scientifically, this phenomenon is referred to as "polymorphism". The 13 fish species that belong to the Central ...
