In Chile, where Darwin saw earthquakes and volcanoes, he began to see what must have happened. The centre of the earth, he decided, was very hot. The surface of the earth was thinner in some places. It was in these places that earthquakes and volcanoes developed. As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He saw volcanic islands in the sea, and wondered how living things had got there. But people who believed every word of the Bible thought that God had made all creatures and Man. But, if that was true, why did some of the fossils look like' mistakes' which had failed to change and, for that reason ,died out? On went Beagle, to Tahiti, New Zealand and Australia. There, Darwin saw coral and coral islands for the first time. How had these islands come about? Soon, he had the answer. Coral was made up of the bodies of millions of tiny creatures, piled up over millions of years— a million years for each island. Darwin wrote it all down in his notebooks. After five years he was home. He was never again the healthy young man who climbed mountains and carried heavy bags of fossils for miles. He set to work, getting his collection in order. And, in 1839, he married his cousin, Emma Wedgwood. It was a happy marriage with ten children. He could be found working in his study, with a child beside him. His first great work The Zoology of the Beagle was well received, but he was slow to make public his ideas on the origins of life. He was certainly very worried about disagreeing with the accepted views of the Church. Happily, the naturalists at Cambridge persuaded Darwin that he must make his ideas public. So Darwin and Wallace, another naturalist who had the same opinions as Darwin, produced a paper together. A year later Darwin's great book, On the Origin of Species by Means of Natural Selection appeared. It attracted a storm. People thought that Darwin was saying they were descended from monkeys. What a shameful idea! Although most scientists agreed that Darwin was right and that the story of Adam and Eve was merely a story, the Church was still so strong that Darwin never received any honours for his work. Many years later, he published his other great work, The Descent of Man. He gave a lecture at the Royal Institution, when the whole audience stood up and clapped. His health grew worse, but still he worked. 'When I have to give up observation, I shall die, ' he said. He was still working on 17,April,1882. He was dead two days later.
