Human kind has been existing for 200,000 years in its present form (Homo sapiens), but before it became what is now, it went through a lot of evolutionary steps to get where it is today.
We can find numerous proofs of this continuous development.
There are people who represent this development because it left some marks on us, more than just body hair.
Even nowadays, there are rudiments of the so-called humans of the distant past.
The following examples are the most interesting ones:
The tendon in your wrist
Put both of your hands on the table with your palms upwards. Connect your thumb with your little finger and lift your fist a little.
Are your tendons visible?
In some cases they are, in some not.
Why is this so?
Well, the palmaris longus tendon muscle is a muscle positioned between the upper arm and wrist.
The wrist movements of this muscle are not longer needed nowadays, so therefore it is not visible more and in thirteen percent of the world population.
What’s interesting is that this muscle does not affect the strength of a person in any way and it does not have any adverse effects, except visually.
The pink point in the corner of your eye
You probably have noticed the pink point in the corner of your eye, but you did not know why it is there.
Next-to-everyone has this pink point, even though it does not have any function anymore.
It is characteristic of the so-called third eyelid, normally seen in reptiles when their eyes are closed.
It is a kind of protective layer of the eye.
This is a memorial of the evolution, even though it is no longer a protection of the eye, because we emerged the eyelashes.
