Known as "Darwin's Bulldog" for his impassioned defense of evolutionary theory, Huxley published this, his most famous book, just a few years after Darwin's The Origin of Species. Unlike Origin, this book focuses on human ancestry and offers a concise, nontechnical survey of mid-19th-century knowledge about primate and human paleontology and ethology.
Unabridged republication of the first edition, Appleton, New York, 1863.
