Biologists studied the faces of 129 adult male primates from Central and South America to answer the question: why are the faces of primates so dramatically different from one another? In the picture (left) faces of male primates from Central and South America. Faces of adult male primates from Central and South America. Warmer colors indicate higher complexity in facial color patterns. Species shown are: (1) Cacajao calvus, (2) Callicebus hoffmansi, (3) Ateles belzebuth, (4) Alouatta caraya, (5) Aotus trivirgatus, (6) Cebus nigritus, (7) Saimiri boliviensis, (8) Leontopithecus rosalia, (9) Callithrix kuhli, (10) Saguinus martinsi, and (11) Saguinus imperator.
