Cichlid fish genome helps tell story of adaptive evolution

Competition breeds new fish species, study finds

Competition may play an important role during the evolution of new species, but empirical evidence for this is scarce, despite being implicit in Charles Darwin's work and support from theoretical studies.

Sandcastle-building fish offer evolution clue

(Phys.org) —In Lake Malawi, East Africa, there are around 200 different species of cichlid fish that once or twice a year build large sand structures (known as bowers) on which the fish mate. Each different species constructs ...

Lizards show evolution is predictable

If you could hit the reset button on evolution and start over, would essentially the same species appear? Yes, according to a study of Caribbean lizards by researchers at the University of California, Davis, Harvard University ...
