WILLIAM KING GREGORY (1876 1970) was an American zoologist, renowned as a primatologist, paleontologist, and functional and comparative morphologist. he was active in presenting his ideas to students and the general public through books and museum exhibits. His studies often had particular significance in the field of evolution; he believed the anatomical structures of fossil and extant species should exhibit relationships. His work charted the evolution from the early fishes through the various branches to birds and mammals. He developed the principle of habitus and heritage theorizing that animals evolved with two sets of characteristics: the heritage features which derived from a long evolutionary history and the habitus characteristics which were adaptations to the environment in which the species existed. He later expanded this to his palimpsest theory which proposed that the habitus features often overlaid and obscured the heritage features. A similar theory, mosaic evolution has appeared since King Gregory's death. He had been elected to the National Academy of Sciences in 1927 and on his death was one of the oldest members.
