Left-Handed People Tend To Have Better Verbal Skills

About 1 in ten people are left-handed and that has been the case for at least the past 10,000 years, according to scientists. Although history shamefully faults out left-handed people are being unlucky, or even malicious, have sharper verbal skills than their right-handed peers. Doctors analyzed the genes of 400,000 people and have found four particular regions of the body that are different in left-handed people.  One of these areas is in the language areas of the left and right sides of the brain that communicate with each other in a more coordinated way. The exact genes that cause left-handedness are not known but the new study, published in the journal Brain, linked four genetic traits or 'regions' with it. Three were linked with proteins that are in turn linked with tiny structures similar to bones within cells, known as microtubules. These tiny molecules form part of the 'scaffolding' inside cells, or the cytoskeleton, which guides how cells are constructed as well as what they do. The researchers found having the left-handed genetic traits affected the cytoskeletons in an area of the brain that joins regions that deal with language. This raises the intriguing possibility for future research that left-handers might have an advantage when it comes to performing verbal tasks, but it must be remembered that these differences were only seen as averages over very large numbers of people and not all left-handers will be similar.
