The human body is a living record of evolution, shaped over thousands of years and still slowly changing today. Even though we look much like our ancestors did 20,000 years ago, small changes continue to happen—often without us noticing.
One example is the palmaris longus tendon in the wrist, a muscle once essential for climbing and movement. As humans no longer rely on it, the tendon has begun disappearing in a growing number of people, offering a quiet glimpse into how evolution is still shaping us.
