Proof of evolution you can find on your body!
Lay your hand face up on a flat surface, your wrist with vein side facing up. Touch and press your little finger with the thumb and raise the hand a little bit from the wrist. If there is a raised band in the wrist, this indicates the presence of a vestigial muscle in your fore arm which are called Palmris Longus. This muscle is missing from one or both arms of 10-15% of the population. Its really useless but check out the video for interesting facts on human evolution.
