Thus, they constitute an excellent group to evaluate alternative hypotheses for the evolution and maintenance of monogamy in primates and early humans. The Owl Monkey Project and the Comparative Socioecology of Monogamous Primates Project are providing invaluable data to examine those questions through field research in the Education Amazon and the Argentinean Chaco.
