More valuable than gold, the means to grab hold
* According to Wikipedia, a thumb is opposable if "is capable of bending in such a way that it can touch all the other digits on the hand." Interestingly, very few species have opposable thumbs.
* My friend Nicholas pointed out the benefit of opposable thumbs the other day (providing the idea for this simple miracle). He commented that without them, our hands just be like flippers on a seal or fins on a fish. We could swat a fly or paddle through water or pin things together using both hands. But holding an object with a single hand would be quite difficult.
* An opposable thumb is valuable for holding objects such as coffee mug handles.
