Structures in the human hand are remarkably similar throughout [[mammals]] and even birds and reptiles. Most [[mammals]] have comparable bones, although significantly distorted (such as in a horse's [[hoof]]).<ref>http://universe-review.ca/I10-82-limbs.jpg</ref> The opposable [[thumb]] makes it possible to grasp branches and manipulate tools. Other than humans, the only other species with oppossable thumbs are other primates, such as [[chimpanzees]], whose hands are also much stronger.
