It’s long been thought we evolved from seasponges, but new genetic research suggests that jellyfish-style creatures mayhave kicked off the human race.
长久以来，人们都认为我们是从海绵动物演化而来的，但是新的基因研究表明人类起源于类似水母那样的生物。
While trying to fill the gaps in the genomesequence of the comb jelly, a gelatinous sea creature similar to a jellyfish,researchers discovered it was related to all other animal species in the world.
在填补栉水母的基因组序列空白时，科学家发现这种生物的基因组序列与其他任何生物都存在关系。
In fact, it shared so many similarities,the researchers went as far to suggest the creature may have been one of ourfirst ancestors.
事实上，这种生物与其他任何生物存在很多相似之处，科学家们大胆猜测这种生物可能是我们的祖先之一。
The research was carried out by scientistsfrom the University of Miami and the National Human Genome Research Institute(NHGRI) in Maryland.
这项研究由来自迈阿密大学和马里兰州的国家人类基因组研究所共同执行。
They wanted to create the full genomesequence of a comb jelly to fill in some of the gaps in knowledge about the creature.
他们想研究出这种生物的基因组序列，以更好的了解这种生物。
For the study, they analysed a particulartype of comb jelly called the sea walnut, or Mnemiopsis leidyi, found in theAtlantic Ocean.
为了这个研究，他们研究了位于大西洋的栉水母。
When they mapped the genome and ran itthrough a computer program, the researchers discovered it shared DNA with allother animals.
他们绘制了基因组并且用电脑程序进行了分析，发现其含有与其他所有动物都一样的DNA。
They were also surprised to find that thespread of its DNA through these other species suggested it may have been thestarting point.
他们还惊喜的发现，DNA在这些其他物种中的传播方式表明这种海洋生物可能就是起点。
More than half a billion years ago a singleline of species separated from all other animals and scientists traditionallybelieved this originated with sea sponges.
在大约5亿年前，有一种物种从其他所有物种脱离开来，科学家一般认为这种物种是海绵动物。
According to findings published in thejournal Science, however, the comb jelly may be 'the earliest branch of theanimal tree and the sister lineage to that of all other animals'.
然而，根据发布在《科学》杂志上的研究报告显示，栉水母可能是动物家谱中的最早分支，与所有其他动物享有同类型的血缘。
This may also impact on the theory that allanimals developed a nervous system and muscles, too.
这些研究发现也可能对所有动物都发展了神经系统和肌肉的理论产生冲击。
Sponges don't have a nervous system ormuscles and when scientists considered them to be our first ancestors, it wasassumed other animals evolved and
developed these features over time.
海绵动物并没有神经系统或者肌肉，当科学家认为海绵动物是我们最早的祖先时，这意味着其他动物在随后的时间里演变和发展了这些神经系统和肌肉特征。
However, comb jellies do have thesefeatures. This means that if they were the first ancestors, some species losttheir nervous systems and muscles, despite the fact they would have given thatspecies a so-called 'survival advantage.'
然而，栉水母确实具备这些特征。这意味着如果它们是最早的祖先，那么某些物种在随后的时间里失去了神经系统和肌肉，尽管神经系统和肌肉可以赋予它们所谓的“生存优势”。
'Having genomic data from the ctenophoresis crucial from a comparative genomics perspective, since it allows us todetermine what physical and structural features were present in animals earlyon,' said author Dr Andy Baxevanis from NHGRI's Division of IntramuralResearch.
“从比较基因组学的角度看，获取栉水母的基因组数据是非常重要的，因为这样我们才能判断早期动物是什么样的物理和结构特点，”一名研究人员如是说。
'These data also provide us an invaluablewindow for determining the order of events that led to the incredible diversitythat we see in the animal kingdom.'
“这些数据额也提供了一个宝贵的窗口，让我们更好的了解导致动物王国物种多样性的事件顺序。

Yes they all evolved into politicians
是的，他们都演变成了政治家。

Politicians, a generally spineless species.
政治家，都是没有脊梁的物种。

I was told we evolved from bacteria. Whatwill it be next week?
不是说我们是从细菌演化而来的吗？下个礼拜又有什么新说法了？
