Fossil footprints. Fossil footprits found in tanzania, confirm that hominids like Lucy walked upright. A volcanic eruption covered the ground with ash 3.75 million years ago. When three hominids then walked across the ash, they left their prints for all time, because the ash hardened and selt. Upright walking has changed our hands and feet. In an ape both are adapted for gripping branches- so they look much the same. In humans the feet are longer and narrower to allow us to run fast, and the big toe is shorter because it has no need to grip. Because the hands are not used for movement they are free to perform other tasks.The thumb and fingers have both become longer to make the hands more skillful.
