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.

This is adaptation....not evolution

[@willowpets]

Adaptation = Evolution.

[@joshb2686]

This is a generational change, not change in one organism's lifetime.

Two group of animals are considered species if they can't interbreed with each other. This meets that requirement perfectly. Also, it's pretty evident that you don't understand anything about species classification or evolution. 'Fish' aren't a single species. Heck, the term technically includes everything from sharks to frogs to birds to mammals. Before accusing other people of being brainwashed, I suggest you remedy your own ignorance first.
