死而复生…在被宣布灭绝后 , 一只克隆的塔斯马尼亚虎 , 时隔八十年再次行走了在这个星球上 。 (译注:即袋狼 , 刚开始我也懵圈了 , 原来这货有三个叫法 , 又叫狼又叫虎 。 )

It sounds like something from a sci-fiB-Movie: scientists have moved a step closer to bringing the Tasmanian tiger back from extinction.
这听起来像是科幻电影中的东西:在如何把已经灭绝的塔斯马尼亚虎复活这个问题上 , 科学家已经取得了重大的进展 。
Also known as the thylacine, or Tasmanianwolf, the world’s largest carnivorous marsupial died out in its native landsometime during the 1930s. Despite almost 4,000 reports of “sightings” since,including tantalisingly inconclusive video footage as recently as 2008, mostregard the species as having gone for ever.
袋狼 , 也被称为塔斯马尼亚狼 , 作为世界上最大的肉食性有袋类动物 , 在20世纪30年代 , 它在它所栖息的土地上灭绝了 。 尽管自那以后有近4000条“目击”报道 , 其中还包括一段于2008年拍摄的吊人胃口的录像 , 但大多数人都认为这个物种永远地离开了我们 。
So the mapping of the thylacine’s geneticsequence, which in theory makes cloning the living animal itself possible,raises tricky questions. How far should we go to reverse the tide of extinction?And what ecological and ethical issues might this raise?
在理论上 , 袋狼的基因测序图谱使对它进行活体克隆成为了可能 , 但这也引出了一连串棘手的问题 。 为了遏制自然界生物灭绝的浪潮 , 我们能做到什么程度?这又会引起怎样的生态和伦理问题?
Professor Andrew Pask of the University ofMelbourne, who led the team sequencing the thylacine’s DNA, has no doubts aboutbringing back lost species, seeing a clear moral obligation to do so. “We wereresponsible for hunting [the thylacine] to extinction – in thatcase, we almost owe it to the species to bring it back”.
【太平洋电脑网:扮演上帝:我们应该复活已经灭绝的动物吗?】墨尔本大学的安德鲁·帕斯克教授领导他的团队从事DNA测序工作 , 他们对复活已经灭绝的物种没有异议 , 因为他们清楚地看到了我们所负有的道德义务 。 “我们应该对人类狩猎活动导致的灭绝负责 - 在这种情况下 , 我们完全应该把灭绝的物种复活” 。
Others are less sure. Some have accusedscientists of “playing God”, while even National Geographic ran the coverheadline “Reviving Extinct Species. We Can. But Should We?
然而还有一群人对此不以为然 。 有人指责科学家是在“扮演上帝” , 甚至连《国家地理》杂志都在其封面刊登了这样的标题“恢复灭绝的物种 。 我们做得到 。 但是 , 我们应该做吗?”
But such concerns may be too late, as thegenie is already out of the bottle. Scientists in Cape Town recently announcedthat the quagga, a dark subspecies of the familiar zebra that went extinct morethan a century earlier, had been revived. The team used selective breeding ofzebras, which showed characteristics of their lost cousin, to “reverseengineer” the quagga into existence.
