Along the same lines, check out the flying squirrel Idiurus Macrotis, an African scaly-tailed flying squirrel. It's beginning to evolve a true wing. There's a bony spur that deploys the wing when the squirrel stretches out its wing membrane. This gives it a wider wingspan (i.e. better glide) than other squirrels, while at the same time giving it more dexterity, since the membrane attaches to its wrist and not its thumbs. Fast forward fifty thousand years, and that spur will be longer, so it gets an even better glide. Fast forward 100,000 and there will be a muscle attached to the spur that lets the squirrel give one flap just before it touches down; that will let it land at a higher weight. Go forward a million years and you'll have a mammal with four legs _and_ wings sticking out of its sides. It's rare to see evolution in action like this, but cool when it happens. http://animaldiversity.ummz.umich.edu/site/resources/Grzimek_mammals/Anomaluridae/Idiurus_macrotis.jpg/view.html Quote Share this post Link to post Share on other sites Join the conversation You can post now and register later.
