13、rles Darwin , was a geologist11 and naturalist fascinated by rocks, plants and animals. He left England on the ship, the Beagle, in 1831. The journey gave him the chance to study various living14 things in their natural environments. After Darwin had spent some time in South America, his room on the
14、 ship was crowded with“ samples1 of the pkints and cinimals he had collected. As he studied these, he asked himself the question： how did different species come to exist1 73. At that lime, people believed that all species had appeared on Earth at the same time , and had not changed since. But Darwin
15、 began to think differently. He noticed that some species of animals were very similar to each other. Maybe animals evolved- as they adapted to their changing environments? It was just an idea, but enough to inspire Darwin to look for more evidence .身4. When the Beagle reached the Galdpagos Islands

17、pected that the finches had evolved from a common ancestor, which had arrived on the islands a long time before. 30ver time, it had slowly evolved into many new species.

20、eagle.译文参考发现之旅1 . “贝格尔号”船长需要招聘一个人，此人能“有机会访问遥远而鲜为人知的国家并从 中受益”。来应聘的人不是船长的首选。他是一个年轻人，没有完成学位课程就离开了医学 院。更有甚者，他最近收到了父亲的一封信，信中预言他将是“他和全家的耻辱”。尽管如 此，他在这艘船上的冒险经历将导致有史以来最重要的科学发现之一。2 .所提到的那位年轻人叫查尔斯达尔文，是一位地质学家和博物学家，对岩石、植物 和动物都着迷。1831年，他乘“贝格尔号”离开英国。这次旅行使他有机会研究自然环境中 的各种生物。达尔文在南美洲待了 段时间后，他船上的房间里塞满了他收集的动植物样本。 当他研究这些
21、样本的时候，他问了自己这个问题：不同物种是如何存在的？3 .当时，人们认为地球上所有的物种都是同时出现的，并且从出现以来就没有过变化。 但达尔文开始有不同的想法。他注意到有些动物彼此非常相似。也许动物是随着适应环境的 变化而进化的？这只是一个想法，但足以激励达尔文去寻找更多的证据。4 . 1835年，当“贝格尔号”到达加拉帕戈斯群岛时，达尔文看到了许多新物种，但最 令他感兴趣的是鸟类。达尔文注意到每一个岛上的雀科小鸟都不相同。它们的喙似乎是根据 那个岛上的食物进化的。5 .达尔文认为这些雀科小鸟是从一个共同的祖先进化而来，这个祖先很久以前就来到了 这些岛屿。随着时间的推移，它慢慢进化成许多新物种。这就是怎么有动植物的新物种存在 的答案：它们是从早期祖先进化而来。6 .这是一个全新的观点一一进化论。达尔文在他的物种起源一书中解释了这一理论。 该书直到1859年才出版，并立即引起了一场风暴。许多人拒绝相信包括人类在内的生物都是 从较低级的生命形式进化而来。他们很震惊。但是达尔文的科学研究非常令人信服，结果越 来越多的人开始相信他的理论。7 .今天，物种起源被认为是有史以来人们所写出的最重要的著作之一。它永远改变 了人们对地球上生命的看法。而这一切都是从“贝格尔号”的旅程开始的。
