Thomas H. Huxley was one of the first supporters of Charles Darwin’s theory of evolution by natural selection, and he did more than any other writer to advance its acceptance among scientists and nonscientists alike. His most famous book, Man’s Place in Nature, published only five years after Darwin’s The Origin of Species, offers a compelling review of primate and human paleontology, and is the first attempt to apply Darwin’s theory to human beings. As compelling a piece of analysis now as it was 140 years ago, Man’s Place in Nature is a must for every science lover’s library.
