The Actual Reasons Why People Look The Way They Do

Do you ever wonder why your face looks the way it does, or more interestingly, what attracts you to the people you find sexy? We know that people can grow beards, and sure, mustaches look great when twirled audaciously, but what is the actual purpose of facial hair? Dimples were so highly sought after that someone once attempted to create a machine that could give you dimples, but what is it about dimples on a face that we find so endearing? A philtrum is also called a cupid's bow for its ability to be so attractive that it can capture your heart, but what is the actual purpose of a philtrum? 

If you're naturally curious as to why you find chins so sexy and why some people have unibrows and others don't, we have the list for you. We've already explained why everyone has nipples, but why do we have fingernails and not claws? Were our fingerprints created specifically to assist forensic investigators? Some of these physical traits serve a purpose, while others are totally vestigial, meaning they don't do anything at all.

  • The Philtrum Is A Point Where Your Face Fuses But It May No Longer Have A Purpose

    The philtrum, more affectionately called the cupid's bow, is the dip in the center of your upper lip with two ridges that connect to your nose. While the philtrum is cute and looks great with a bold lipstick shade, it's an important part of embryonic development. The philtrum forms at 3-4 months of a fetus's growth, when two important developmental phases fuse, the nasomedial and maxillary processes. That is why so many children are born with a cleft lip, which is caused by a disruption in the formation of the fetus. 

    Studies also show that people with a defined philtrum are considered overwhelmingly more attractive.

  • Chins May Safeguard The Jaw From Mechanical Stresses, Or Maybe They’re Just Really Sexy

    Chins, the bony mass in the front of the lower mandible, are unique to humans. The reason they exist may be complicated. There’s a good chance that chins developed because of the amount that humans used their jaws for talking and chewing.

    More recently, biological archeologists found that throughout history, males with stronger, larger chins had a better chance of passing on their genes. This indicates large chins are an indicator of good genes, making them more attractive to potential mates. 

  • Butt Cheeks Allow Us To Walk On Two Legs

    Have you ever noticed that humans have bigger butts than just about any animal? Even our closest relatives, primates, have pretty flat butts in comparison to ours, which sometimes have the capability to rest a champagne glass on top of, which was proven to us by Ms. Kim Kardashian.

    Why do humans have big butts? We’re the only animals that walk on two legs instead of four or more. The large amount of muscle and fat on our butts helps us stand and walk on our two legs.

    Different Nose Shapes And Sizes Could Aid Temperature Regulation In Different Climates

    Noses come in a wide variety of shapes and sizes, to the benefit of many cosmetic surgeons. Why are there so many different types of schnozes? Evolutionary biologists believe that the heat and humidity of the climates humans evolved from caused the variety.

    The colder and dryer a climate is, the more narrow the nose is. This allows the body to warm the air before it enters the lungs in an attempt to regulate heat in the body. For humans who evolved in hotter and more humid environments, their air needs less warming and moistening before reaching the lungs, hence the wider nostrils.

  • Different Skin Colors Developed To Regulate Folate And Vitamin D In The Body

    When we look at anthropology and science, it’s obvious that the closer to the equator people evolved, the darker their skin became. The reason humans have varying skin tones does directly relate to the intensity of the sun, but it’s much more complicated than you might think. 

    The pigmentation of human skin is nature’s balancing act of two vital minerals humans need to thrive: folate and vitamin D. The problem is the sun destroys folate while humans need the sun for vitamin D. Melanin in the skin blocks harmful UV rays that break down folate while allowing the skin to absorb enough sunlight to produce vitamin D. But the amount of melanin is dependent on the amount of the body gets, and the varying amounts create variations in skin color.

    Dimples Could Make Our Facial Expressions More Noticeable

    Scientists have been fighting over the purpose of dimples for years. It may seem obvious why dimpled cheeks are adorable: they remind us of babies. Some scientists believe the genetic purpose of dimples is for the same reason. They subconsciously send the message of youth and health, causing other humans to want to mate with you. 

    Another explanation is that dimples allow facial expressions to be more prominent. The extra definition allows communication through a smile, or lack thereof, more possible.
