The eyebrow - the useless person

Scientists believe that human eyebrows are more dense now, harder and play a role. But recent research shows not.

According to the BBC, over millions of years of evolution, modern people removed almost all of the body's neck-haired gibbons but still retained some useful details, including eyebrows.

In the past, scientists believed that human eyebrows were thicker, harder, and playing a role, such as supporting the chewing of food or being used as a "weapon " to scare people. Enemy, beasts.

Recently, the research team from York University (Canada) used 3D technical software to reproduce the eyebrows of a skull dating back to 125,000-300,000 years of heidelbergensis (Homo heidelbergensis), and analyzed eyebrows. this with the tasks it can take.

As a result, Ricardo Miguel Godinho, an evolutionary anthropologist in the research group, said that eyebrows do not have any benefits as previous studies are mistaken.

The study - published in Nature Ecology & Evolution, argues that the original human being is just a social communication tool.

Along with narrow forehead, more smooth, eyebrows help modern people adapt to life to communicate more in labor and living together to survive.

In fact, what we think and act today comes from the need of our ancestors. Social communication is the most important reason that natural selection decides to leave human eyebrows in the process of evolution.

With the ability to move the eyebrows, modern people easily create relationships with the community better, more widely, thus having friends, allies, can express emotions to find partners .

Today, many people agree that eyebrows also protect the eyes from rain, sweat and other debris falling into the eye socket.

The York University team also said that social communication is one of the most important factors that helps people survive and develop for thousands of years. From that shows that the role of eyebrows is really important.

Scientists believe that if evolution does not retain eyebrows, people will evolve a certain part that plays a role as an eyebrow.

Eyebrows are also among the facial features that are prominent, a key element of human identification .
