Why is no human face like anyone?

The current world population is over 7 billion people. But there is one fact to admit: that is, among them we cannot find two identical faces, even though we are twins.

After conducting many studies over the years, scientists at the University of California Berkeley (USA) have found the reason why our face is like no one - that's because of evolution.

To draw this conclusion, the scientists collected data and analyzed 1,000 combined genes compared with the physical characteristics of different subjects. Experts expect to see the correlation between the human gene and the differences mentioned above.

Is genetic genetics the cause of the difference between our faces?

However, the result is that genetic genes have a certain influence on body characteristics such as height and weight . but the impact to form the face is not in accordance with any certain rules.

Experts continue to study and realize that the real solution lies in the evolution that people experience. In particular, the characteristics that help people survive better will be retained and developed.

In thousands of faces, we still recognize what is "that person" in some way!

The difference in face between people is such a characteristic. It helps us distinguish different individuals of the same species, like the sniffing characteristics of dogs or penguins calling for relatives.

Specifically, thanks to the distinctness of each face, people are able to identify different objects with an accuracy of up to 97.53%.

This number is even higher than the ability to automatically receive faces up to 97.25% of Facebook. In particular, facial features that help us distinguish this person from others are the three eyes, nose and mouth (distance, size, thickness .).

However, another issue that has been mentioned is that many people now have prosopagnosia syndrome . Simply put, this is a 'face blindness' disorder , ie, the inability to distinguish the difference between people and faces.

People with this condition face huge problems during social interaction. So, in the future, experts are looking to find other ways to distinguish people from people to help those who are prosopagnosia.

The study was published in the journal Nature Communications.
