Claude Owen Lovejoy (born February 11, 1943) [a] is an evolutionary anthropologist and anatomist at Kent State University Ohio. He is best known for his work on Australopithecine locomotion and the origins of bipedalism.[1][2] "The origin of man", which he published in Science in January 1981, is cited as among his best-known articles.[1] The 'C' of his name stands for Claude, but he never uses the name and is known only as Owen.
