It is likely that at some point an acquaintance or relative told us that he saw a person very similar to us. scientists, in charge of new study, They mentioned that while it is very difficult to find someone who is 100% identical to us, someone who is 75% or 80% like us should already be among the more than 7.9 billion people inhabiting the planet. Land Currently.
The report was presented by a team from Josep Carreras Leukemia Research Institute and published in the journal Cell reports. Manel Estellerthe leader of this group, decided to study the reasons why there are people with very similar faces who are not relatives, and for this he contacted Francois BrunelCanadian artist who has dedicated himself since 1999 to photographing similar people around the world.
Science explains similar unrelated faces
Brunel helped esteller and his team recruited about 32 pairs of volunteers for testing, and the resulting photographs were analyzed by three software from face recognition. In the case of twins, numbers of 90% to 100% were achieved, but in the case of random people who didn’t even know each other, the two programs found a correlation level of 75% in 16 of these pairs.
The results obtained showed that genes The common ones corresponded to different parts of the face, such as the eyes, lips, mouth, and nostrils, in addition to some others, such as bone formation in the skull and genes associated with skin texture or fluid retention, as they differentiate facial volumes.
To find the answer to the question why this similarity, the team examined biological material, genome, epigenome (chemical grades that control DNA) and microbiome (types of viruses and bacteria that inhabit our body). The first two were the ones that paired similar people, and the other two separated them.
Research shows that two people who are paired with similar faces have genetics very similar; i.e. both have common sequences DNA that they are similar. This similarity does not occur because both individuals are related by blood, but rather by chance, which creates identical regions or DNA sequences in both organisms.
Other results of studies on similar faces
Other important data found during the investigation shows that the volunteers were similar not only in their physical characteristics, but also in their behavior. The couple filled out questionnaires with more than 60 questions about their lifestyle habits, and some of them were found to have similarities. smoking and The level of education there were some of the behavioral traits that were correlated, suggesting that common genetic variations might also influence their personalities or habits.
The team responsible for this study believes that the results obtained can be applied in biomedicineWell identified genes and their respective variants may also be involved in pathology. For example, a person’s genome can be relatively deduced from a face for screening. genetic diseases. Besides, in Criminalistics, as it can be used to create a system capable of reconstructing the face of a perpetrator or victim without the need to identify them. DNA.
