Growth data from a number of species of Old and New World primates have been analyzed by calculating instantaneous relative growth rates. Species discussed are the New World species Saimiri sciureus and Saguinus nigricollis , and the Old World species Pan troglodytes and Macaca mulatta. The analysis of the perinatal growth data indicated that differences in relative growth rates are present during early periods of growth. More specifically, it was found that the closer taxonomically a species is to man the greater the deceleration of growth during the first postnatal year. It is suggested that this may be a general primate trend.
