HAND IT TO ‘EM Top game changing lefties as scientists discover why some people write with their left hand

Among the world’s smartest and most successful are Barack Obama, Paul McCartney, and Albert Einstein.

Left-handedness is now explained by a change in the brain anatomy.
The study also validates what lefties have always claimed: they are stronger verbal communicators than righties.

Scientists have been unable to explain why one in ten people is left-handed.

The Oxford University study studied the genomes of 400,000 people, 38,000 of whom were left-handed.

Using brain imaging, scientists identified four genetic areas of the brain that were significantly different from right-handers.

Three of these locations were connected to proteins that shape the brain.

They altered white matter tracts in the brain, particularly in language centres.

According to senior author Gwenaelle Douaud, “the left and right parts of the brain communicate more coordinated” in lefties.

The study also found a link between left-handedness and a decreased risk of Parkinson’s disease and a higher chance of schizophrenia.

This is the first time the gene regions responsible for left-handedness have been found.

As a result, some cultures perceive left-handedness as unlucky.

Several prominent lefties, notably Leonardo da Vinci and Bill Gates, have slowly destroyed this notion.

Now science has caught up, mapping the DNA structures that underpin the trait.
