Scientists believe that human eyebrows used to be bushier than they are now, stiffer and play a role. But recent research shows that’s not the case.
According to the BBC, over millions of years of evolution, modern humans have removed almost all of the ancient ape’s hair from their bodies, but still retain a few useful details, including eyebrows.

In the past, scientists believed that early humans’ eyebrows were denser, stiffer and played a role, such as assisting in the process of chewing food or used as a “weapon ” to scare off enemies. enemies, beasts.
Recently, a team from York University (Canada) used 3D engineering software to reconstruct the eyebrows of a 125,000-300,000-year-old skull of heidelbergensis (Homo heidelbergensis) and analyzed the eyebrows. this with the tasks it can undertake.
As a result, Ricardo Miguel Godinho, an evolutionary anthropologist on the research team, said eyebrows did not have any benefits as previous studies had mistakenly believed.

The study, published in the journal Nature Ecology & Evolution, suggests that the original human eyebrows were merely a social communication tool.
Along with the narrow inward, flatter forehead, the eyebrows help modern people adapt to the life of having to communicate more in work and life in order to coexist.
In fact, what we think and act today is rooted in the needs of our ancestors. Social communication is the most important reason that natural selection decided to leave human eyebrows in the process of evolution.
With the ability to move the eyebrows, modern people easily create better and broader relationships with the community, so that they have friends, allies, can express emotions to find a mate. .

Today, many people agree that eyebrows also have the ability to protect the eyes from rain, sweat and other debris falling into the eye sockets.
The York University team also said that social communication is one of the most important factors that have helped humans survive and develop for thousands of years. That shows that the role of eyebrows is really important.
Scientists think that, if evolution did not keep the eyebrows, humans would still evolve a part that plays the role of eyebrows.
Eyebrows are also one of the most prominent facial features, the main factor used to identify people .
