Have you ever wondered why there is a line above the lips and under the nose and what its purpose is?
It is called 'Philtrum' in medical parlance and in practice it is not for any purpose or aimless.
So the question is why does it happen on every face?
In fact, this line is formed in the mother's womb, because in the beginning of pregnancy there is a time when every child loses its face.
After two to three months, changes begin to take place and the face begins to form.
First the nostrils and then the mouth are formed and then they move to the place where everyone has nose and mouth.
So when the nose and lips reach their place, this line appears.
Sometimes the nose and lips do not move properly, so the cut lips are visible on the face.
This line is common not only in humans but also in most mammals and it is also meaningless for them.
But it is also useful in cats and dogs, and it helps their sense of smell.
