Laughlin, William S. (1919-)

US physical anthropologist, biobehavioral scientist, student of E. A. Hooton; became an acknowledged authority on the population biology and prehistory of Native Americans. His theory of the origins of Native Americans postulated one migration out of Asia approximately 17 kya. From this ancestral population, according to Laughlin, branched the Aleuts and Eskimos while, on the southern margin of Beringia; the remaining populations migrated southward down the ice-free corridor to colonize the rest of the New World. His work is summarized in The First Americans: Origins, Affinities, and Adaptations (1979).
