Thomas Henry Huxley was one of the first adherents to Darwin’s theory of evolution by natural selection, and did more than anyone else to advance its acceptance among scientists and the public alike. Huxley was a passionate defender of Darwin’s theory so passionate that he has been called “Darwin’s Bulldog”. But Huxley was not only the bulldog for Darwin’s theory, but was a great biologist in his own right, who did original research in zoology and paleontology. Nor did he slavishly and uncritically swallow Darwin’s theory, he criticized several aspects of it, pointing out a number of problems.

He made a major contribution to the studies of primate evolution and expressed his idea that the human species is a part of natural world.
