Charles Darwin was a scientist who changed our understanding of the natural world.  He is known as the Father of Modern Biology.  Darwin  spent all his life studying nature and making notes about all the species(物种)he found.
Darwin was born in 1809 in England. Like many geniuses he didn't do well at school and got poor marks.  He was a good athlete though and loved exploring nature and collecting sea shells. He also kept doing chemistry experiments and so his classmates gave him the nickname "Gas"
His father was a doctor and expected Charles to become one too.  Charles started studying medicine at Edinburgh University, but soon gave up his studies there.  He went on to study religion at Cambridge University instead. There he started collecting insects like beetles and paid too little attention to his studies.
In 1831，at the age of 22 ,  Darwin went on a five-year expedition to South America , Australia and South Africa by ship.  He was often seasick, but the things he saw on this long journey changed his life.  He collected many fossils as well as animal and plant specimens.  He spent the rest of his life studying what he had seen and he wrote many books.
In 1839, Darwin married his cousin, Emma Wedgwood, with whom he had ten children!  He was a loving father and enjoyed family life, which was always more important to him than his research. In spite of having many health problems throughout his life, Darwin lived until he his 73.
Darwin's most famous book On the Origin of Species came out in 1859 and sold out in a day.It said that all living things were related, which meant that human beings were just another kind of animal. These ideas were not popular at first, but now most people agree with them and admire Darwin as a brilliant scientist.
