The intimacy between man and nature began with the birth of man on the earth，and becomes each century more intelligent and far­reaching.To nature，therefore，we turn as to the oldest aim most influential teacher of our race；from one point of view once our task­master，now our servant；from another point of view，our constant friend，instructor and inspirer.

Charles Darwin was born in 1809 in England.At school he didn't do well and got poor marks.He was a good athlete though and loved studying nature.He also kept doing chemistry experiments.

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.

In 1831，Darwin went on a five­year journey to South America，Australia and South Africa by ship.He was seasick but the things he saw on this trip changed his life.He collected many animal and plant specimens.

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 was 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.His ideas were not popular at first，but now most people agree with them and admire Darwin as a great scientist.
