Do you have this left over trait from human evolution?

Did you know that there are a ton of traits we all carry that are defunct and left over from our evolution? Many of them serve absolutely no purpose to us today, but did thousands-to-millions of years ago. One of those traits in a special muscle in the forearm that our ancestors used to climb trees. The muscle is called theย Palamaris Longus but not everybody still has it, and even less have it in both arms. Do you?

To test: rest your arm flat on a solid surface, then lift your hand up and connect your thumb with your little finger. If you carry this trait, you should now see your Palamaris Longus! Fun fact: we actually don't use this muscle and surgeons sometimes use it in reconstructive surgery ๐Ÿ˜ฎโ€๐Ÿ’จ
