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