Longtime friends who live in Atlanta don’t matter. Their ancestry didn’t come from the same part of the world. Malone’s family hails from the Bahamas and the Dominican Republic. Chasen’s family came from Scotland and Lithuania. Nor are they the result of a deep family secret.But they are strikingly similar. It’s not just brown hair, beard and glasses. It is also the shape of the nose structure, cheekbones and lips.
“Michael and I got back a long time ago, and it’s been a lot of fun for us because over the years we’ve been misunderstood for each other all over Atlanta,” he said. Chasen told CNN’s Don Lemon. “It created some really interesting situations just because people thought we were strangers.”
The two are so similar that even facial recognition software had trouble distinguishing them from identical twins. But now scientists think they can explain why they are so similar.
A new study suggests that even people who look like each other but are not directly related may have genetic similarities.
Many of the people with these genetic similarities also had similar weights, similar lifestyle factors, and similar behavioral traits such as smoking and level of education. It may mean that you
Dr. Manel Esterer, a researcher at the Josep Carreras Leukemia Institute in Barcelona, Spain, said he had worked on twins in the past, but the project will focus on similar but real family relationships. I’ve been interested in people who don’t. It goes back nearly 100 years.
art leads to science
The researchers asked the pair to do a DNA test. The pair filled out questionnaires about their lives. The scientists also put images of themselves through his three different facial recognition programs. Of the people they recruited, 16 pairs had similar scores to identical twins identified using the same software.The remaining 16 pairs appeared identical to the human eye. Maybe, but in one of our facial recognition programs, the algorithm decided otherwise.
Next, the researchers took a closer look at the participants’ DNA. The pairs that the facial recognition software judged similar had more genes in common than her other 16 pairs.
“We were able to confirm that they are similar to humans. In fact, they share some genetic mutations, and these are very common among them,” Esteller said. says. “So they share these genetic variants that are related in the way they have the shape of their nose, eyes, mouth, lips, and even bone structure. And this is what genetics put them together.” That was the main conclusion.”
They are similar codes, he said, but that’s just a coincidence.
“There are so many people in the world right now that eventually the system will produce humans with similar DNA sequences,” Esteller said. This has probably always been true, but now with the internet it’s much easier to find them.
A closer look at the pair revealed that other factors differed, he said.
“There’s a reason they’re not exactly the same,” says Esteller.
When scientists took a closer look at what’s called the epigenome of the most similar doppelgangers, they found even greater differences. Epigenetics is the study of how environment and behavior alter the function of human genes. When scientists looked at the microbiomes of the most similar pairs, they were also different. The microbiome is the microorganisms (viruses, bacteria and fungi too small to be seen by the human eye) that live inside the human body.
“These results not only provide insight into the genetics that determine our faces, but may also have implications for establishing other human anthropometric and personality traits.
This study has limitations. Due to the small sample size, we cannot say that these results apply to larger similar groups. Although the researchers believe their findings vary in larger groups. It is unknown whether the same is true for
Real-world applications of science
Gripp uses facial analysis software in his work with patients who may have a genetic condition to assess facial features of the patient that may indicate a particular genetic condition.
“While this is slightly different from the study, it points in the same direction that changes in a person’s genetic material affect facial structure, which was actually confirmed and used in this study.” In contrast, some others, like the microbiome, seemed less relevant.
Regarding the nature versus nurture question the research raises, Gripp believes that both are important.
“As a geneticist, I am a firm believer that nature and genetic material are very important to almost everything, but that does not deny that nurture is just as important.” I don’t think it’s one or the other, because there are so many factors to be successful in the world, and the environment is so important.”
“Applying this research to the real world presents a potential pitfall where digital facial analysis tools can misidentify someone,” Grip said.
“If you think about things like facial recognition software that often open a computer screen, there is a possibility of misidentification. says.
However, the study seems to suggest one conclusion. We may not be all that unique, at least physically.
“I think we now have someone who looks like us, a double,” Esterer said.
While some prefer individual looks, Malone, who happens to befriend his double, is encouraged by the fact that his looks aren’t one-of-a-kind. made it intimate. He believes that if more people knew how similar they were to others, they too could find common ground, especially in this polarized world.
“We realized we were all connected,” Malone said. “Humanity probably starts small, so we are all connected.”
