200 years ago today, July 26, 1825 (June 11, 1825 in the lunar calendar), was the birth of the British naturalist Huxley. British naturalist Huxley (1825-1895) was born in London on July 26, 1825. He had only two years of primary education. Later, he taught himself French, German, Italian, Latin, Greek and other languages, read extensively, and studied hard. Served in the British Navy. He is a member of the Royal Society and many other societies, chairman of the British Association for the Advancement of Science, and has served as principal of many schools. Huxley has published more than 150 scientific papers, covering not only zoology and paleontology, but also geology, anthropology and botany. He is particularly famous for his research on marine animals. He once pointed out that the inner and outer body walls of coelenterates are equivalent to the inner and outer germ layers of higher animals. Huxley was an active supporter of Darwinism. He vigorously promoted the theory of evolution, fought fiercely against the religious forces of the time, and further developed Darwin's thoughts. He was one of the first scholars to raise the question of the origin of mankind. In 1893, at the age of 68, he was invited by a friend to give a famous lecture at Oxford University, entitled "Evolution and Ethics", which mainly talked about the natural forces in the evolutionary cosmic process and the artificial forces in the ethical process. The fundamental issues of mutual stimulation, mutual restraint and interdependence of forces. It provides a scientific explanation of biogenesis and biological evolution, a big step forward than Darwin's "The Origin of Species". Yan Fu (1853-1921), a modern enlightenment thinker and translator in China, translated some of Huxley's works, called "The Theory of Evolution". He called on people to save the nation and "compete with heaven for victory" with the view of "natural selection, survival of the fittest", which had a great influence on the ideological world at that time.
