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.
My daughter is left-handed, and she has great skills, she thinks fast and I think left-handed people are very emotional, now I don't know if they are all :)
