You Can Use Your Fingers As Proof Of Evolution

Simple trick shows the ways in which humans are still evolving

Evolution is a truly remarkable thing. It’s amazing to think that all of the different species on our planet have evolved and changed over millions of years. And evolution isn’t stopping! This neat little trick proves it.


We may be a highly-evolved species, but we’re not perfect. We have organs like the appendix that we don’t really need. We have wisdom teeth that cause all sorts of problems. We have hair growing in odd places. We get goosebumps in the cold, but they don’t make us warmer.

Evolution clearly has some work still to do.

Some people assume that evolution in humans has stopped, but recent findings show that our bodies are still changing over the years. For example, our ancestors used to have a particular tendon in their forearms, used for climbing and swinging from trees.

Some of us still have this tendon, but an increasing percentage of the population is being born without it.

This is quite an exciting discovery because it shows that the process of evolution is still ongoing. We can only imagine what sort of changes will occur to humans in the centuries to come. Maybe, many years from now, they’ll look back at pictures of us and wonder why we look so strange!

So, this particular tendon has the scientific name palmaris longus, and you can actually use a simple little technique to check whether or not you have it. All you need to do is put your hand out in front of you, with the palm facing up. Bend your wrist slightly towards you and touch your pinky finger to your thumb. The tendon, if you have it, will appear along your wrist. Here’s a video to explain more:

Experts believe that around 1 in 10 of us don’t have the tendon, and it doesn’t really make any physical difference to the way people live in the modern world. If you don’t have it, you can say that you’re slightly more evolved than most other people!
