Behavior May Influence Evolution

eldavojohn writes "Pending your beliefs about evolution, National Geographic is running an interesting article on the influences of behavior on evolution. The study supports the controversial idea that an animal's behavior in response to environmental change can spur evolutionary adaptations. By adding a predator to an island where a species of lizards lived with no predators, they witnessed a quick shift in the average length of legs on the lizards. Long legs meant to escape were useless against the new larger predators while short legs became the dominant feature since they increased climbing ability (to trees the predators could not reach).

Re:Why I Used the Word 'Controversial'

Also, everything about evolution is controversial?

Not quite. Everything about science in general is "controversial".

Abridged Dictionary

Science - n.: Tool used by liberal activists to promote their radical agenda.

Controversial - adj.: Promoted by the liberal elite media.

Oh, but economics is not "controversial" when it's the right sort (tax cuts, eliminate government except where it helps your constituents).

Is it really that bad in America?

Yes. And the Democrats have had several weeks now and have not fixed it. Golly; I was sure they would make everything better.
