Have you ever wondered how evolution works?
Our bodies carry several remnants from our ancestors, features that no longer serve a purpose today. One such fascinating trait involves a tendon in the forearm, and it’s quite simple to check if you possess it.
How to Check for the Tendon
Here’s a quick experiment to see if you have this evolutionary remnant:
- Place your arm on a table with your palm facing up.
- Touch your thumb and pinky finger together.
- Slightly lift your hand off the table.
Do you see a tendon bulging from your forearm? Most people do. This tendon, known as the palmaris longus, was originally used by our ancestors to swing from tree to tree. However, as our lifestyle has evolved, this tendon has gradually become redundant.
The Evolutionary Shift
Interestingly, 90% of the population still has this tendon, but for 10% of us, it has disappeared. This change is a subtle sign of human evolution at work. If you don’t see the tendon, congratulations! You’re part of the small group showcasing this fascinating evolutionary advancement.
What Does It Mean?
The presence or absence of this tendon doesn’t affect your daily life; it’s merely an interesting marker of how our species continues to evolve. So, whether you have it or not, it’s a unique trait that highlights the ongoing journey of human evolution.
Take a moment to try this experiment and share your findings with friends and family. Are you part of the 10% or the 90%?
