Although Old World primates as a rule give birth only to single offspring, multiple births are known to occur. However, they occur only rarely and this may have discouraged detailed research on this topic, with the last comprehensive review dating from 1948. Nevertheless, explicit statements about the frequencies, causes and sonsequences of multiple births in Old Wold primates have been repeatedly published in the primatological literature.
This monograph reviews and examines published data on multiple births in nonhuman catarrhine primates. This review reveals that:
Examination of the original data shows that most current concepts concerning multiple births in Old World primates are not supported by available evidence. Nevertheless, certain general principles emerge from this review that may assist future research.
