had arisen who was no longer necessarily subject to change with the changing universe,—a being who was in some degree superior to nature, inasmuch as he knew how to control and regulate her action, and could keep himself in harmony with her, not by a change in body, but by an advance in mind. Wallace distinguishing between mind and body was asserting that natural selection shaped the form of man only until the appearance of mind; after then, it played no part. Mind formed modern man, meaning that result of mind, culture. Its appearance overthrew the laws of nature. Wallace used the term "grand revolution". Although Lubbock believed that Wallace had gone too far in that direction he did adopt a theory of evolution combined with the revolution of culture. Neither Wallace nor Lubbock offered any explanation of how the revolution came about, or felt that they had to offer one. Revolution is an acceptance that in the continuous evolution of objects and events sharp and inexplicable disconformities do occur, as in geology. And so it is not surprising that in the 1874 Stockholm meeting of the International Congress of Anthropology and Prehistoric Archaeology, in response to Ernst Hamy's denial of any "break" between Paleolithic and Neolithic based on material from dolmens near Paris "showing a continuity between the paleolithic and neolithic folks," Edouard Desor, geologist and archaeologist, replied: "that the introduction of domesticated animals was a complete revolution and enables us to separate the two epochs completely." A revolution as defined by Wallace and adopted by Lubbock is a change of regime, or rules. If man was the new rule-setter through culture then the initiation of each of Lubbock's four periods might be regarded as a change of rules and therefore as a distinct revolution, and so Chambers's Journal, a reference work, in 1879 portrayed each of them as:...an advance in knowledge and civilization which amounted to a revolution in the then existing manners and customs of the world. Because of the controversy over Westropp's Mesolithic and Mortillet's Gap beginning in 1872 archaeological attention focused mainly on the revolution at the Palaeolithic–Neolithic boundary as an explanation of the gap. For a few decades the Neolithic Period, as it was called, was described as a kind of revolution. In the 1890s, a standard term, the Neolithic Revolution, began to appear in encyclopedias such as Pears. In 1925 the Cambridge Ancient
