It turns out that if you have a tendon protruding from the underside of your wrist, you actually have physical signs of evolution attached to your body

But neat as it is, other than spooking your friends with Machinist impressions, a protruding wrist tendon doesn’t really have a purpose; therefore it’s known as a vestigial structure.

Vestigial structures are body traits left over from evolution that have no discernible use for us modern humans. That includes things like tailbones, goosebumps and that pesky appendix. These are different from other traits humans have evolved to no longer require because instead of phasing out entirely – like the tail – they remain present in the body for reasons that remain a mystery to many scientists.

It’s known as the palmaris longus and it turns out most people have it – in fact, those of us who don’t are actually reasonably rare at 14% of the general population.

It is believed that the palmaris longus was used by humans years ago to activate the wrist’s flexibility. However, it has no effect on the modern human’s body.

In fact, the tendon’s presence is so benign that it’s very common for it to be removed and used in tendon grafts or cosmetic surgery.
