科学家们发现了第一个与左撇子有关的基因指令。这类指令好像还与大脑的结构和功能密切相连，特别是与语言有关的地区。Around one in ten of us is left-handed - but why A team at the University of Oxford1 analysed 400,000 peoples DNA2. They then compared lefties and righties in a giant game of genetic3 spot-the-difference.每十个人中就有一个人是左撇子，但这是为何呢？牛津大学的一个研究小组剖析了 40 万人的 DNA（脱氧核糖核酸）。然后，他们通过一个基因 找不一样 游戏对左撇子和习惯用右手的人进行了比较。They found four genetic instructions that influenced left-handedness. These seem to work by altering how the brain develops. Theyre involved in building the intricate scaffolding, known as the cytoskeleton that organises the inside of our bodys cells and culminate4 in a brain that is wired differently in left-handed people. Scans showed regions of the brain involved in language were better connected and more coordinated5 as a result.他们发现了影响左撇子的四种基因指令。这类指令好像是通过改变大脑的发育来起用途的。指令参与构建复杂的 脚手架，即细胞骨架，它组织大家体内的细胞，最后形成一个架构有别于惯用右手的人的左撇子大脑。扫描结果显示，左撇子的大脑中与语言有关的地区连接得更好，也更协调。The researchers speculate the findings may give left-handed people greater verbal skills. The study also showed slightly higher risks of schizophrenia and slightly lower risks of Parkinsons disease in left-handed people.研究职员推断，这类发现可能证实左撇子拥有更强的语言能力。此项研究还显示，左撇子患精神分裂症的风险略高，患帕金森病的风险略低。
