How It Works

Humans and primates (monkeys, apes and gorillas) have what are called “opposable thumbs” which makes doing certain tasks much easier. Our thumbs are attached to a different part of our hand than our other fingers, and the thumb can move separately. This challenge probably helped you appreciate how useful our opposable thumbs are. They are an external part that helps humans survive.
