---Charles Robert Darwin
The captain of the ship, the Beagle, wanted someone who would “profit by the opportunity of visiting distant countries yet little known”. The person who answered the call was not the captain’s first choice. It was a young man who had left medical school without completing his degree. What’s more, he had recently received a letter from his father predicting that he would be “a disgrace to yourself and all your family”. Despite all this, his adventures on this ship would lead to one of the most important scientific discoveries of all time.
He was not the captain’s first choice.
He was a disgrace to himself and all his family.
He was a young man who had left medical school without completing his degree.
The young man in question, Charles Darwin, was a geologist 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 living things in their natural environments. After Darwin had spent some time in South America, his room on the ship was crowded with samples of the plants and animals he had collected. As he studied these, he asked himself the question: how did different species come to exist
Charles Darwin was a geologist and naturalist, fascinated by rocks, plants and animals.
How did different species come to exist
Charles Darwin was a geologist and naturalist, fascinated by rocks, plants and animals.
All species had appeared on Earth at the same time, and had not changed since.
Animals evolved as they adapted to their changing environments.
To look for more evidence.
At that time, people believed that all species had appeared on Earth at the same time, and had not changed since. But Darwin 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.
Darwin noticed finches’ beaks had evolved according to what food was available on that particular island.
New species of plants and animals evolved from earlier ancestors.
When the Beagle reached the Galápagos Islands in 1835, Darwin saw a variety of new species, but it was the birds that interested him the most. Darwin noticed that there was a difference between the finches on each of the islands. It seemed their beaks had evolved according to what food was available on that particular island.
Darwin suspected that the finches had evolved from a common ancestor, which had arrived on the islands a long time before. Over time, it had slowly evolved into many new species. And that was the answer to how new species of plants and animals came to exist: they evolved from earlier ancestors.
A _________ ancestor
__________ into different species
common
evolve
It was a completely new idea—a theory of evolution. Darwin explained this theory in his book, On the Origin of Species. It was not published until 1859 and immediately caused a storm. Many people refused to believe that living things, including humans, had evolved from lower forms of life. They were shocked. But Darwin’s scientific studies were so convincing that more and more people started to believe his theory.
Today, On the Origin of Species is regarded as one of the most important works ever written. It has changed ideas about life on Earth forever. And it all began with the journey on the Beagle.

“猎犬号”的船长希望找到一个“会因为这个可以游历鲜为人知的遥远国度的机会而受益”的人。响应号召的这个人并非船长的首选。这是一个没有拿到学位，从医学院辍学的年轻人。而且，他最近收到了一封他父亲的来信，信中预言他将成为“自己和全家人的耻辱”。即便如此，他在这艘船上的冒险经历将促成有史以来最重要的科学发现之一。

我们提到的这个年轻人——查尔斯·达尔文——是一位地质学家和博物学家，他对岩石、植物和动物着迷。1831年，他乘坐“猎犬号”离开英国。这次旅行让他有机会研究自然环境中的各种生物。达尔文在南美洲度过一段时间以后，他船上的房间里满是他收集的动植物样本。当他研究这些时，他问了自己一个问题：不同物种是如何产生的？
At that time, people believed that all species had appeared on Earth at the same time, and had not changed since. But Darwin 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.
那时，人们认为地球上的所有物种都是同时出现的，并且从此再无变化。但达尔文开始有了不同的想法。他注意到，一些动物种类彼此间十分相似。也许动物在适应环境变化时进化了？这虽然只是一个想法，但足以激励达尔文去寻找更多的证据。
When the Beagle reached the Galápagos Islands in 1835, Darwin saw a variety of new species, but it was the birds that interested him the most. Darwin noticed that there was a difference between the finches on each of the islands. It seemed their beaks had evolved according to what food was available on that particular island.
Darwin suspected that the finches had evolved from a common ancestor, which had arrived on the islands a long time before. Over time, it had slowly evolved into many new species. And that was the answer to how new species of plants and animals came to exist: they evolved from earlier ancestors.
1835年，当“猎犬号”抵达加拉帕戈斯群岛时，达尔文看到了各种各样的新物种，但最令他感兴趣的是鸟类。达尔文注意到，每个岛屿上，雀类都有所不同。它们的喙似乎是根据所在岛屿上可觅得的食物类型进化而来的。
达尔文猜想这些雀鸟是从一个共同的祖先进化而来的，而该祖先很久以前就来到这片群岛了。随着时间的推移，它慢慢进化成了许多新物种。这就是动植物的新物种如何产生的答案：它们从更早期的祖先进化而来。
When the Beagle...in 1835为when引导的___________从句；主句是but引导的并列句，其中第二个分句中it was the birds that interested him the most为____________。

这是一个全新的理念——进化论。达尔文在他的《物种起源》一书中解释了该理论。这本书直到1859年才出版，并立即引起了轰动。许多人拒绝相信包括人在内的所有生命都是从更低级的生命形式进化而来的。他们感到震惊。但是达尔文的科学研究是如此具有说服力，以至于越来越多的人开始相信他的理论。
如今，《物种起源》被认为是有史以来最为重要的著作之一。它彻底改变了人们对于地球上生命的看法。而这一切都始于“猎犬号”的探索之旅。
