Key adaptation - Asymmetrical bimanuality

All the great apes have a form of opposable thumb, but there鈥檚 more to dexterity than this useful digit. Great apes can do something with their hands that virtually no other species can. Most animals can only use their two hands, or paws, or hooves, symmetrically. They cannot perform asymmetrical movements with each hand at the same time. Great Apes, however, can. To us it鈥檚 such an ordinary ability that we take it for granted, but buttoning a shirt or unscrewing a jam jar would be impossible if our hands could not perform different roles at the same time. Asymmetrical bimanuality, as it is known, is a complicated skill which takes a lot of brain power. It is one of the reasons that great apes are to be the most sophisticated tool users on the planet.
