Evolutionary genetics and implications of small size and twinning in callitrichine primates.
New World monkeys (NWMs) are characterized by an extensive size range, with clawed NWMs (subfamily Callitrichinae, or callitrichines) such as the common marmoset manifesting diminutive size and unique reproductive adaptations. Perhaps the most notable of these adaptations is their propensity toward multiple gestations (i.e., dichorionic twins and trichorionic triplets). Indeed, with the excepti...
متن کاملThe Fossil Record and Primate Phylogeny
Fossils provide the only direct evidence of the evolutionary history of primates. A method of phylogeny reconstruction is outlined which is based on an evaluation ofphenetic resemblances of fossils interpreted in their stratigraphiccontext. This stratopheneti¢ approach to phylogeny involves three successive steps: (1) organization of fossils stratigraphically, (2) phenetie linking of similar fo...
متن کاملSocial and developmental influences on urinary androgen levels in young male white-faced marmosets (Callithrix geoffroyi).
Callitrichine primates (marmosets and tamarins) often remain in their natal groups beyond the time of sexual maturity. Although studies have characterized the development of female reproductive function in callitrichine offspring, less is known about the male reproductive development. To document reproductive development in male marmosets, we monitored urinary androgen (uA) excretion in males h...
متن کاملNovel simian homologues of Epstein-Barr virus.
Thirty different lymphocryptoviruses (LCV), 26 of them novel, were detected in primates by a panherpesvirus PCR assay. Nineteen LCV from chimpanzees, bonobos, gorillas, and other Old World primates were closely related to Epstein-Barr virus (EBV), the type species of the genus lymphocryptovirus. Seven LCV originating from New World primates were related to callitrichine herpesvirus 3 (CalHV-3),...
