Another interesting question is based on our pinky fingers and toes. Are they necessary? The answer is no, or rather, not quite. Surprisingly, the only "necessary" toes on our feet are the big toes; to keep perfect balance. However, this is still under debate, as some believe that all toes are needed and some do not. With our hands, the main fingers said to be necessary are the thumbs and index fingers. Apparently, to be able to grasp things, all you really need are these two fingers, the other fingers simply help out in doing the same task but without the thumb and index fingers would be unable to do it at all. Wow!
