What Do People’s Faces Really Look Like, According To Scientists?

By Kath Bane

In Science, the theory of the evolution of human is a famous subject. People believe that humans evolved from apes, gorillas or chimpanzees. Is that really the case?

They say people have unique faces but it is possible to share similar features with a stranger. It is also believed that chimpanzees are the closest animal relatives of a human. During the primitive eras, people observed that chimpanzees are really doing well in imitating them.

Meanwhile, a new research study has come to life adding up to the things these animals are good at. According to Discover, the researchers from Leiden University in the Netherlands and Kyoto University in Japan teamed up for this study. They came up to a conclusion that chimpanzees can "process images of other chimps' rear ends."

The way they process the butt's image is similar to the way people see their faces. Although, these animals can barely identify the backside especially when turned revered. Humans also experience it, thus they termed it as "inversion effect".

The NYMag explained that the authors made an experiment on this. Volunteers were asked to pair identical sets of human faces and sets of rear ends. It was admitted that both humans got a difficult time solving the puzzle and recognizing the butts when it was flipped around.

Another experiment made was when they changed the images into grayscale. The result, however, did not change leading to a conclusion that colors play a vital role in recognizing a person with his behind on in the crowd. It was confirmed that chimpanzees are adapted to easily recognizing each other by looking at each other's butt.

Scientists say that faces identify people but butts are the definition of a face to chimpanzees. Now, what do people's faces really look like? Share your thoughts in the comment section below!
