It’s always interesting to compare the differences between people, and some of the more intriguing ones to see are some of the oddest differences! My personal favorite difference is the palmaris longus! This also happens to be one of the easiest to spot genetic differences.
The palmaris longus is a tendon that is located in your forearm. The muscle was once used for hanging and climbing, but it is not used much, if at all, anymore, leaving it a mark of a bygone time. They’ve done tests on grip and maneuverability and have yet to find any difference between those with the muscle and those without. Today, 14% of the human population is actually missing the muscle completely! Some people are even only missing it in one arm!
How do you know if you have one of these muscles? It’s simple! Lay your arm flat on a surface like your desk or table, then touch your pinky finger to your thumb. Slightly lift your hand from the table, leaving your arm flat. Do you see the muscle pushing up out of your skin? If not, you’re one of the 14% of people without it!
