People in its present form havr existed for 200,000 years. Before that, it took a lot of time and a lot of rvolutionary steps to get where we are today.
Evidence od this continuous development can stil be seen in some people today because they left some marks on us, which are much than body hair. Even today, you can still finf rudiments od the so-called humans.
Here are the most interesting examples:
- The tendon in your wrist
Extend your hand with the palm upwards, then connect the little finger and thumb together while raising the fist. Some people will see a tendon pop out, while others won’t. The reason for this is the palmaris longus tendon muscle, located between the upper arm and wrist. The muscle movements in the wrist are not required anymore, which is why a big part of the world population doesn’t have the tendon. Except visually, this muscle doesn’t have any kind of effect on our strength.
- The pink point in the corner of your eye
Have you ever wondered what the pink point in the corner of your eye does? Well, nothing now, but it was our third eyelid in the past. We got eyelashes to protect our eyes, a function which was done by the third eyelid in the past.
- Wiggling ears
Ear wiggling nowadays is considered as a funny trick, but in the past it had an important function. People wiggled their ears to locate sounds and recognize danger, similar to how dogs and cats react to certain sounds.
- Wisdom teeth
You probably had to remove a wisdom tooth at some point in your life because it is completely unnecessary. However, in the past, this tooth had a chewing function as people often ate grass roots. As the food became lighter and softer, our jaw shrunk in size and the wisdom tooth lost its function.
- Getting goose
Have you ever wondered why we sometimes get goose bumps? Well, this is a rudimentary function of the body left from the days we were actually covered in fur. When our hairs get up in a potentially dangerous situation, we look bigger and more dangerous to the attackers – well, at least we did in the past.
