Our bodies are amazing products of evolution, constantly changing, even if we don’t notice it. A small example of this is the palmaris longus tendon in our wrist.
This tendon, which helps animals like lemurs move between branches, is gradually disappearing in humans. While about 90% of people still have it, some have lost it without any major effects on their daily lives.To check if you have the tendon, place your palm up on a flat surface, touch your pinky to your thumb, and lift your hand slightly. If you see a band in your wrist, you have it. This slow, ongoing evolution shows how our bodies continue to adapt to the world, even in subtle ways.
