Scientists have discovered a gene （基因）that plays a role in violence （暴力）in men illtreated in childhood . The discovery could explain why some experience unhappy childhoods and go on to normal lives , while others turn to violence , crime of antisocial deeds . But it will also restart another argument .
Terrie Moffitt and Avshalom Caspi report in Science today that one common form of a gene in the brain makes men more likely to be violent-but only if they have experienced cruelty or rejection in childhood . The researchers followed up the life histories of 442boys born in New Zealand in 1972 . Of these , 154 had been illtreated in the first 10 years , 33 of them badly . They had either experienced sexual attack , beatings or rejection by mother or stepparents . Of the 154 children , 55had a less active variant （变异体）of a gene called MAOA, and 99had the more active variant . The 55 boys were more than twice as likely to have been in trouble than the other ill-treated group . They made up 12% of the total , but were responsible for 44%of all crimes from among the 442 boys .
Prof Moffitt thought a "violence" gene had not been discovered . Boys with the less active form who were not ill-treated during childhood lived normal lives . "It is very common in the population . One third of us have it ."she said , "So the gene doesn't do much of anything , it doesn't cause any trouble in any way , unless we are also ill -treated".
The gene might also show the ability to bear mental stress. The army or the police might examine the applicants （申请人）to see if they have the more active form . But the discovery also raises the argument that people with the less active form of the gene could be social dangers ,to be treated with medicine . "This research can easily leads people to fix social problems through medical treatment ," said David King of the UK Gene Alert Group .

科学家们已经在童年时遭遇过虐待的男性身上发现了一种在暴力方面起重要作用的基因.这个发现可以解释为什么有些人经历了不愉快的童年却能过上正常的生活而另一些却走上了暴力、反社会的道路.但是这个发现也会重新引起一场争论.
参与该研究的 Terrie Moffitt 博士和 Avshalom Caspi博士在《今日科学》中报导称：脑部有一种常见的基因可以使人有暴力倾向------但这个倾向也只有当他们在童年时经历过残酷的遭遇或遗弃时才会出现,研究家们仔细追查了1972年出生在新西兰的442个男孩的生活轨迹,在这些人中,154个人 十岁以前受到了虐待,其中33人是受到严重的虐待.他们或者受到性侵害、或遭到殴打或被母亲、继父继母抛弃.在这154个人中55人产生了一种叫 MAOA的99人产生了更为积极的变异基因 .这55个人比其他遭遇过不幸成长起来的人要多两倍陷入困境的可能.这55个人占总研究究人数的12% ,但他们占了这442个人所犯罪行中的44%.
Terrie Moffitt 博士认为有一种“暴力基因”还没有被发现,含有消极变异基因而童年时没有遭遇虐待的孩子能过上正常的生活.“这在人群中很常见,我们有三分之一的人有消极变异基因”（但这些人没有都走上犯罪道路）她说：“所以基因并不代表什么,它不以任何方式带来任何麻烦,除非我们也被虐待.”
这个基因也许可以表明一个人承受精神压力的能力.部队或警察或许可以通过检查应征者来看他们是否有积极基因,但这个发现也许可能引发争议即消极基因的人可能成为社会危险因素或他们应该接受药物治疗.“这项研究可能很容易使人通过药物来解决一切社会问题 ,” 英国基因协会的David King 说.
