What Next?

Uh, oh! It's been confirmed that polar bears are breeding with grizzly bears now. What's next? Cats breeding with dogs? ^_^

Seriously though, we are seeing evolution at work. As the polar bear's natural habitat shrinks, they will move into areas where they will have to compete for resources. That competition will require adaptation. One adaptation might be new species suited to the new conditions. Isn't nature wonderful?

Some species won't adapt fast enough and will die out. Humans will be among of those. Our reproduction is too restricted for evolution to save us. Our intelligence will allow us to hang on for quite some time but if our habitat changes too severely, we don't stand a chance.
