Hello my friends, The feature we 'no longer need' in our body: the Palmaris Longus muscle. This muscle is lost between 1.5% and 63.9% worldwide today. According to a study, this loss rate in the Turkish population is 26.6%. -Place the back of your hands on a flat surface and touch your thumb and little finger. -Do you see a double muscle on your wrist? Its name is Palmaris longus. -Don't worry if you can't see it. 18 percent of people no longer have this muscle, and its absence is not a deficiency. Which one do you have? Good luck.
