But the research team, led by Dr. Angela Milner, a paleontologist at the British museum, wrote that until their investigation of Archaeopteryx, "little was understood about the extent to which its brain and special senses were adapted for flight."

但是由大英博物馆古生物学家杰拉米尔纳博士领导的研究团队写道：直到他们研究始祖鸟，对于始祖鸟的脑和特殊感觉因应飞行而发生了何种程度的改变的认识尚知之甚少。

Previous studies of the feathered wing and tail of Archaeopteryx and its birdlike anatomy, including a pronounced wishbone, supported the prevailing view of experts that it was capable of some degree of powered flight.

之前关于始祖鸟带羽毛的翅膀，尾巴以及它类似鸟类骨骼的研究，支持专家们公认的观点，即它能做某种程度的动力飞行。

In a statement issued by the museum, Dr. Milner said, "If flight was this advanced by the time Archaeopteryx was around, then were birds actually flying millions of years earlier than we'd previously thought?"

在博物馆编写的综述中，米尔纳博士写到，如果出现始祖鸟的时候飞行就已经到了如此高级的阶段，那么鸟类是否实际上比我们先前考虑的时间还要早数百万年就飞行了呢？

Dr. Milner said the new study not only established that Archaeopteryx was capable of "controlling the complex business of flying," but also showed "how much there is still to discover about when and how bird flight began."

米尔纳博士讲到，新的研究不仅显示始祖鸟能够控制飞行这样一种复杂的事，而且显示出海洋多少官员鸟类何时和怎样开始飞行的事情尚未发现。

Measurements of the semicircular canals, the mechanism for balance inside the ear, showed that Archaeopteryx had the "neurological and structural adaptations necessary for flight," the scientists concluded.

科学家总结道，对这种鸟的耳内控制平衡的机制半规管的测量显示，始祖鸟拥有了“为了飞翔所必需的神经的和结构的相应改造”。

The researchers, at the Natural History Museum in London, based their findings on the first X-ray examination and reconstruction of the braincase and inner ear of a 147-million-year-old Archaeopteryx specimen.

Thanks to its thick feather-shafts, most scientists do think Archaeopteryx could fly, but the newly discovered leg feathers wouldn't have played a great role in that.

由于它的羽轴粗大，大部分科学家都认为始祖鸟会飞，但最新发现的腿部羽毛可能对它的飞翔并不起多大作用。

However, this find of archaeopteryx fossils are from a much earlier age, lower in stratus and more primitive in features than previously discovered archaeopteryx.

而这次始祖鸟化石的发现，比先前发现的鸟化石时代更早，层位更低，特征更加原始。

So, Archaeopteryx probably evolved feathers to entice mates or communicate, which were then gradually "recruited for aerodynamic functions."

所以，始祖鸟进化出羽毛可能是为了吸引配偶或交流，之后才渐渐地“有了飞行功能”。
