In his theory, he declared that different types of living creatures on the earth had not been created suddenly but had been developing over thousands of millions of years. He believed that the survival of the fittest was the law in the struggle of life on earth. His ideas were not imaginative. He had gone on a long journey to different parts of the world and studied the animal and plant life he found. Darwin lived on until 1882. He wrote many books throughout his life. But the Origin of Species was one of the most famous pieces of writing.
