1940年,遗传学家阿尔弗雷德•斯特蒂文特发表了一篇论文,声称基因决定了你能否卷舌头——能卷舌头的父母会生出能卷舌头的子女。
Just 12 years later, geneticist Philip Matlock disproved this finding with a study of his own. When he compared 33 sets of identical twins, he found that seven of those pairs contained one twin that could roll his or her tongue but the other couldn't.
才过了12年,基因学家菲利普•马特洛克就用自己的研究推翻了这一发现。马特洛克比较33对同卵双胞胎后发现,其中有7对双胞胎一个会卷舌头,另一个不会。
Since the genes of identical twins are the same, genes clearly weren't the deciding factor for tongue rolling. Still, the misconception persists 65 years after Matlock published his debunking study.
既然同卵双胞胎的基因是相同的,基因显然不是能否卷舌头的决定因素。尽管如此,在马特洛克发表了这项颠覆性研究65年之后,仍有人持有这种误解。
And though it's not life-threatening, that misunderstanding can cause unnecessary stress. As evolutionary biologist John McDonald told PBS, he's received emails from children concerned that they aren't related to their parents because they don't share the ability.
尽管这种误解不会危及生命,但还是会带来不必要的压力。进化生物学家约翰•麦克唐纳告诉美国公共广播公司说,他曾收到孩子写来的电子邮件,写信的孩子担心自己不是父母亲生的,因为父母(自己)会卷舌头而自己(父母)不会。
