Investigative Question: How is the evolution of opposable thumbs a genetic advantage?
Background: Only apes and primates have hands capable of grasping objects. The grasp is made possible by the opposable thumb, so called because it moves opposite to the rest of the fingers. In humans, the thumb can move farther across the hand than in any other primate. In this experiment you will compare your performance of a series of tasks using your thumb and fingers together with your performance of the same tasks without the aid of your thumb. Take a look at your thumbs. Move them around.
This lab is going to get kids thinking and having fun by trying to do ordinary activities WITHOUT their thumbs!!
