Sticklebacks are a species of freshwater fish that have undergone a dramatic evolutionary radiation since the last Ice Age. Ancestral marine sticklebacks populated the newly created lakes and subsequently adapted to different environments. A number of sub-species have recently evolved multiple changes in their anatomical and physiological traits. Stickleback More...species are therefore a good model with which to study adaptive evolution. Less...
