Over the years, humans have evolved significantly. From apes
to modern human beings, our environment has shaped our bodies like any other
creature that has adapted to survive. Whereas our Neanderthal ancestors were
much hairier and apelike, today we have lost much of that body hair and
stockiness.
Our eyebrows, however, have stuck around. Why, when many
people simply pluck them out anyway, haven’t our bodies stopped making them?
For one thing, they have gotten thinner. However, many scientists believe that
eyebrows still provide a unique and needed function: they shield our eyes from
sweat, rain, and other hazards.
If we didn’t have eyebrows, our bodies may have developed
another method of protection for our eyes. According to Greg Foot of Head Squeeze, that could have included
things like giant eyelashes or a much larger forehead that looks a bit like a
shelf.
Eyebrows are also one of the most expressive parts of our
bodies, allowing us to show others that we are angry, shocked, curious, or
otherwise emotionally effected—without saying a word. Check out the Head Squeeze video below to get a
complete rundown of eyebrows and why we still need them after all these years.
