The cause of the human face no one resembles anyone

Through analyzing the genetic sequence of thousands of people, researcher Michael Sheehan and his colleagues discovered the mystery behind our looks.

A recent study by a team of experts at the University of California, Berkeley, shows that genetic genes are the determining factor for different people.

Expert Michael Sheehan - research author and his colleagues conducted data collection and analysis of thousands of different individuals. The measurements are very specific and detailed: the distance of the eyes, the height of the nose . until the calf length.

All indicators on the body, especially the face are collected and analyzed

After analyzing, they realized that the face was the most special part. If the characteristics of the legs, arms and other parts are fully predictable, then we cannot do this with the face.

This is the only part that is completely different from each person, no one is like anyone and can be considered as a natural identity card of each individual.

We can never find someone who has the same face as me, including twins

To understand the cause of the phenomenon, experts continue to analyze the genetic sequence of 836 people from different continents. In particular, they focused on studying 59 small segments of DNA that regulate facial features.

They found that these passages were very complicated, much more so than the genes that set height, weight, etc.

At the same time, when comparing the genes of modern humans to the genes of ancient Neanderthal and Denisovan, experts realized that the diversity of the human face is an evolutionary trait for a long time.

Therefore, over time, depending on the environment, living conditions and circumstances of each individual, the genetic changes will follow the faces of their next generations will have corresponding changes.

Sheehan said, in fact, this is not uncommon in organisms. If the genetic gene helps humans without anyone, the same thing happens with Polistes fuscatus wasps.

Hornets also own differences in each face like humans

Accordingly, in beehives with thousands of individuals, this species can still distinguish each species thanks to its unique face and color characteristics.

The study was published in Nature Communications.
