Ever wonder what that little groove below your nose is for?

According to Tech Insider, it’s called a philtrum and falls into place as our nose and lips form in the womb. In a way, it’s the centerpiece that are faces form around.

Dr. Michael Mosley explains, according to IFL Science, that “It is the place where the puzzle that is the human face finally all comes together. The three main sections of the puzzle meet at your top lip, creating the groove that is the philtrum.”

As for if it has a practical purpose after birth, scientists haven’t figured out any — at least for humans, that is.

While humans and most mammals don’t seem to derive a benefit from having a philtrum throughout life, for cats and dogs it actually increases their sense of smell.

What do you think about this? Have you ever wondered what those floaty things are in your vision, and why they seem to bounce around? The answer is fascinating.
