Two strange people are very similar, maybe because of similar DNA?

Science Fiction Network August 24 (Wang Xiuxia) Isn't it twins, but looks like it? This situation is not uncommon in life. Recently, a new study in the "Cell Report" magazine explained the reason. People with similar faces may be because of similar DNA.

Marnell Estler is a member of the Spanish research. He first led the team to collect 32 pairs of avatars that look similar to but are strangers worldwide, and use three different facial recognition algorithms to determine an objective similarity measurement standard to ensure that these photos are effective. of.

After complex research, they found that these individuals have similar gene types, but they are different at the level of apparent genome and microbial groups. In other words, genomics make these people have similar faces, while apparent genome and microbiology have caused their differences in other aspects.

In addition, these 32 pairs of people were also required to complete a questionnaire on biological statistics and lifestyles, and provided their saliva DNA for multiple groups of analysis. The results show that physical characteristics (weight, height, etc.) and behavioral characteristics (smoking, education, etc.) are also related to the shaping of similar looks.

The study provides a rare opportunity to perceive human similarity. It reveals that the strong similarity of the face is related to the common genetic mutation and provides unique insights for the molecular characteristics of the potential facial structure.

Although the study has a small number of samples, these findings may provide molecular basis for applications in various fields such as biomedical, evolution, and forensic medicine in the future. For example, in the field of biomedicine, you can understand the genome clues that he already possessed according to the patient's facial photos; in the field of forensic medicine, you can rebuild the criminal's face through DNA.
