Made for an easy firm grasp on a branch large enough to hold the animal's weight, it is so perfectly shaped that it's not just the hand as a whole that wraps around the branch. Even some of the individual bones look like they're gently curved for a good fit.
How not to envy the orangutan's hands, when one of your own fingers has already given up bending where it's supposed to?
Still, it's good to recall that those curved bones aren't enough to let the orangutan type. And also that this particular one is already a skeleton.
And that his whole species may be on the way out the door.
And that its exit is our doing.
