LEFT-HANDED people have unique GENES **Every tenth person on Earth is left-handed**. British scientists found dozens of genes only in left-handed people - and came to interesting conclusions. Every tenth person on Earth is left-handed, and this strangeness, in a world where everything is adapted to "right-handers", has always attracted attention. The vague realization that humans become left-handed as a result of some kind of mutation appeared in 2019, when scientists from Oxford discovered several genes that right-handed people did not have. This year, Australian colleagues from the QIMR Berghofer Institute for Medical Research in Brisbane found even more “left” genetic differences: 41 unique genes.
The British analyzed the genomes of about half a million people, the Australians - 1,766,671 people. Based on these data and some other surveys, it turned out that 10% of the respondents were left-handed, which coincides with previous findings. Along the way, seven more characteristic genes were found, thanks to which the so-called ambidexters are born - those that use both hands equally well. They are especially appreciated in special services because, say, they can use weapons with both hands equally well.
**They are more creative!** Among the famous artists and scientists there are a large number of "leftists": Leonardo da Vinci, Isaac Newton, Albert Einstein, Nikola Tesla, Ivan Pavlov, Pierre and Maria Curie, Charlie Chaplin, Marilyn Monroe, Angelina Jolie, Brad Pitt, Mila Jovovic, Bruce Willis , Sylvester Stallone, Julius Caesar, Bill Gates, Napoleon, Oprah Winfrey, Jimi Hendrix ... It is logical that the unique - "left" genes change the brain, affecting its structures and functions. But what exactly they bring and how it manifests remains to be seen. Also, it is still unclear why nature "set" that the right-handed are nine times more.
There is another interesting fact: there are as many as 21 left-handed people among the twins, which is significantly more than the average. Left-handed people think faster when they play computer games or play sports, they are impatient, and they easily get bored of monotonous activities. Also, they are more reckless, they find it harder to orient themselves in space, and they are supposedly scared faster than right-handed people. Greater creativity is also attributed to them, since it is believed that their right cerebral hemisphere is more active.

I wonder if and how many people there are in the world who can normally use both hands and left and right, great article.
Some believe that it is already possible to determine in the womb whether the child will be left-handed. There is a study that showed that 85 percent of embryos lean to the right as early as about ten weeks.
I'm not left-handed, but when I try, I write very well with my left hand
I learned from developmental and child psychology that left-handed children are more creative, more imaginative. Earlier, children who were left-handed were prevented from writing with their left hand, which negatively affected their emotional development. That was a big mistake.
Left-handed people used to be considered a disadvantage and were forced to use their right hand instead of their left. It is now known to be genetically predisposed and there is a normal relationship to it.
I am not left handed, but I think this is truth. I love Novak Djokovic, but Nadal is left handed and there is some creativity in his game play and make him strong within his physical strength. Thank you!
My son is left-handed. I am glad to learn that there are famous people among left-handed people, as well as scientists.
It doesn't have to mean that left-handed people are more intelligent. I work at school and I have experience!
