(Phys.org)—A small team of researchers with members from the U.S. and Switzerland has found an example of a fish that did not always benefit in the end from an evolutionary change. In their paper published in the journal ...
A team of biologists affiliated with multiple institutions in Switzerland and Tanzania has found that early cichlid diversification in Lake Victoria led to their success in deep parts of the lake. In their study, reported ...
A pair of researchers at Central Michigan University has found that cichlid fish that brood their young in their mouths eat up to 40% of their offspring. For their paper published in the journal Biology Letters, Jake Sawecki ...
The evolution of a new species by hybridization from two already described species without a change in chromosome number is very rare in the animal kingdom. So far, only a few accepted empirical examples exist for this spontaneous ...
