    One of the most famous scientists to study adaptations (适应能力) was Charles Darwin (达尔文). He was

born in England in 1809. He wasn't the best student in his school, but when he was 16,his father sent him to

a medical school. Charles liked spending time outdoors observing (观察) nature more than attending medical

classes and dropped out without graduating.

    Next, Charles'father sent him to school to become a minister (牧师). This time he made it to graduation,

But he didn't want to do the work of a minister. His friends encouraged him to follow his interest in science.

    After graduation, Charles was invited to sail on the Beagle as an unpaid scientist. He wasn't the first choice,

but he was the lucky one to go. The Beagle was to travel to South America and then around the world. The

crew's task was to make maps of the places they visited.

    On December 27th, 1831 Charles Darwin sailed from England on the Beagle. The trip was planned to last

two years. In fact, it lasted five. During this time, he saw many amazing things. He collected lots of plants

and animals and took them back to England to study.

    Twenty-three years later, Darwin published an scientific paper with another man named Wallace. Darwin

described how some animals have adaptations that help them survive. They are passed on to offspring (后代).
