Surprising Fact: Do twins not only look alike, but behave alike?

An interesting phenomenon that scientists are still spending a lot of time and effort understanding and even attracting photographers or curious citizens is the "double", or doppelgänger. Even, there are many people who believe that somewhere in this world of nearly 8 billion people, there will be someone who looks exactly like you, although not related by blood.

Even many superstitious people think that the twin is an unlucky phenomenon or it is due to "disguised devil". Or, according to ancient Egyptian mythology, it was believed to be a twin soul with identical consciousness and emotions. Of course, these beliefs have no scientific basis but only rely on spiritual and magical factors to explain things that people cannot understand.

The phenomenon of "twins" - Two people who are not related by blood but are very similar.

However, the view of the ancient Egyptians seems to have some persuasive implications, according to a new study.

This study, based on 32 unrelated doppelgänger pairs from around the world, shows that 2 people with strong facial similarities are significantly more likely to share similar genomes, and even have the same behavior. However, the genes that are activated or the microbiome in the body are still different.

These unrelated "twins" never knew each other, but were found through the painstaking project of Canadian photographer and artist François Brunelle - who has spent 25 years finding and photographing the twins. parallel person.

The study's lead author, director of the Josep Carreras Leukaemia Research Institute in Spain, said that the genotypes of people with similar faces are very similar.

Is personality greatly influenced by genes?

For the study, these 32 pairs of twins completed questionnaires about lifestyle and biometrics in their native language. Then, they filtered out 16 pairs that were considered by 3 face recognition algorithms to have the highest similarity for further research.

They went on to find that the people were very similar in many ways, such as smoking habits, education levels and even weight - an indication that behaviors can be strongly influenced by genes.

The phenomenon of anthropomorphic people is not too rare, as many celebrities also confuse fans because their appearance is so similar to someone else.

The researchers stress that the results not only have genetic implications, but also have implications for answering questions related to shaping people: How do we behave based on human behavior? Is it partly determined by genes, or is it due to lifestyle and environmental influences?

Perhaps most interestingly, these genetic similarities between unrelated doppelgängers occurred by chance, implying that the number of samples from which the human genome can be generated is finite. term, especially on a planet that is rapidly approaching a population of 8 billion.

The researchers say their findings could be used in fields such as evolution, biomedical and forensics

"These results will have implications in the future in forensics - reconstructing a criminal's face from DNA - and in genetic diagnosis - a patient's face photograph will give you genomic clues." his or hers," said one researcher. "Through collaborative efforts, the ultimate challenge will be to predict human facial structure, based on genes and other factors."

Photographer who spent 2 decades looking for duplicates

Since 1999, François Brunelle has traveled to 25 cities to find 250 pairs of twins to create a unique set of images in her photography career.

The series "I'm not a look-alike" (roughly translated: "I'm not a copy") is Brunelle's attempt to find out the answer to this interesting phenomenon. He let two identical people stand side by side, taking black and white photos with similar expressions, costumes and hairstyles.

Though completely alien, that similarity magically binds these two people together.

Notably, among the strange "twins" he found, there are people who are different in gender but have surprisingly similar facial features. The photo was taken the first time the two met, but their expressions and faces make it impossible not to think that these are twins or brothers who have lived together for decades.

Though completely alien, that similarity magically binds these two people together. More specifically, many of the pairs of them have similar personalities and behaviors, making biometric scientists even more excited.
