Scientists Identify Left-Handedness Genes

The study was conducted by researchers from the University of Oxford and published in ‘Brain.’. It analyzed the DNA of nearly 400,000 people, with 38,332 of them being left-handed. . Scientists were able to isolate four genetic regions associated with left-handedness. Three of the regions are believed to influence brain development, which leads to higher coordination between the left and right hemispheres. This implies that left-handed people may also be more adept at verbal tasks. Scientists believe that a more in-depth study is needed to assess whether the “higher coordination of the language areas” is responsible for increased verbal ability. . ... 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, Akira Wiberg, University of Oxford, via CNN
