Ordered series of primate skeletons. The Frontis engraving by Waterhouse Hawkins from the first edition of Huxley's 1863 \Evidences as to Man's Place in Nature\". In this book Huxley presented his evidence that man was descended from the apes. It was published in reaction to Darwin's \"On the Origin of Species\" 1859. Though this image is often interpreted as indicating a line of descent, it is more intended to show ordered variation in limb bones and posture as well as the clear skeletal similarities in the group. The image has been quoted as an inspiration for Rudolph Zalinger's famous Time-Life 1965 image \"The Road to Homo Sapiens\" (page 40-45, Nature Library Early Man). That iconic image has become known as \"The March of Progress\". The artist for this work, Benjamin Waterhouse Hawkins, was famous for his pioneering dinosaur reconstructions but lectured against Darwinian evolution."
