March of Progress
The March of Progress, originally titled The Road to Homo Sapiens, is an illustration that presents 25 million years of human evolution. It was created for the Early Man volume of the Life Nature Library, published in 1965, and drawn by the artist Rudolph Zallinger. It has been viewed as a picture of the discredited theory, orthogenesis, that evolution is progressive. As such, it has been widely parodied and imitated to create images of progress of other kinds. The picture of progress in evolution was anticipated by Thomas Henry Huxley's 1863 Evidence as to Man's Place in Nature.
