The evolution of new traits with novel functions has always posed a challenge to evolutionary biology. Studying the color markings of cichlid fish, Swiss scientists were now able to show what ...

It all started with the Convict cichlids. The small striped fish, native of Central America, captured Sac State Biology Professor Ron Coleman’s attention in a laboratory at the University of Toronto ...

The rapid formation of 500 different species of fish in a single lake, each with specialized ecological roles, resulted from a small but genetically diverse hybrid population. Scientists show the ...

Cichlids are one of the largest and strangest groups of vertebrate fish — fish with backbones — on Earth. They’re popular as pets and farmed in aquaculture, and scientists have been studying them ...

A new study that looked at gut length variation between cichlid fish species found that some of the genetic loci for the trait are sex-specific even though males and females of the same species have ...

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 ...

The analysis of fossils in sediment cores from Lake Victoria, Africa, reveals that a group of cichlid fish rapidly diversified as the lake got larger and provided new ecological niches, whereas the ...
