原文及翻译
What Darwin realized was that certain characteristics could help an animal or a plant to survive and reproduce. Individuals that lacked those characteristics would become more likely to die without reproducing.
达尔文意识到，某些特征可以帮助动物或植物生存和繁殖。缺乏这些特征的个体更有可能死亡而无法繁殖。
Over many generations, the useful characteristics would then become more and more common as the surviving individuals pass the characteristics onto their offspring. Eventually, after many generations, the changes would be so great that a new species would exist.
经过许多代，这些有用的特征将变得越来越普遍，因为幸存的个体将这些特征传递给了后代。最终，经过许多代，变化将如此之大，以至于出现了一个新的物种。
In this way, a single species could divide into two or more new ones. This was called the process of evolution by natural selection.
这样，一个物种就可以分成两个或多个新物种。这被称为自然选择进化的过程。
When Darwin returned to England, he studied plants and animals in more detail. After much research, he began writing a book about his theory of evolution by natural selection. When the book, "The Origin of Species," was published in 1859, it was very popular and very controversial.
达尔文回到英国后，对植物和动物进行了更详细的研究。经过大量研究，他开始写一本关于自然选择进化理论的书。《物种起源》于 1859 年出版，非常受欢迎，也引起了很大争议。
During the next 20 years, Darwin continued his scientific research and he wrote several more books. By the time of his death in 1882, many biologists had realized that Darwin had made one of the most important scientific discoveries of all time. For the first time, scientists could understand the origin of the many different species of plants and animals.
在接下来的 20 年里，达尔文继续他的科学研究，并写了几本书。到 1882 年他去世时，许多生物学家已经意识到达尔文做出了有史以来最重要的科学发现之一。科学家首次能够了解众多不同种类植物和动物的起源。
