Stickleback Evolution

Paul Andersen describes microevolution and macroevolution in the stickleback fish of Loberg Lake. He describes how anadramous fish repopulated the lake after poisoning and adapted to the new environment through natural selection. He also explains how reproductive isolation has appeared in fish that have diverged only a few decades in the past.
