Rethinking Primate Origins Again
In 1974, Cartmill introduced the theory that the earliest primate adaptations were related to their being visually oriented predators active on slender branches. Given more recent data on primate‐like marsupials, nocturnal prosimians, and early fossil primates, and the context in which these primates first appeared, this theory has been modified. We hypothesize that our earliest primate relatives were likely exploiting the products of co‐evolving…
Diurnality, nocturnality, and the evolution of primate visual systems
Much of the recent research on the evolution of primate visual systems has assumed that a minimum number of shifts have occurred in circadian activity patterns over the course of primate evolution. The evolutionary origins of key higher taxonomic groups have been interpreted by some researchers as a consequence of a rare shift from nocturnality to diurnality (e.g., Anthropoidea) or from diurnality to nocturnality (e.g., Tarsiidae). Interpreting t…
Fossil Record of the Primates from the Paleocene to the Oligocene
Hindlimb adaptations in Ourayia and Chipetaia , relatively large‐bodied omomyine primates from the Middle Eocene of Utah
North American omomyids represent a tremendous Eocene radiation of primates exhibiting a wide range of body sizes and dietary patterns. Despite this adaptive diversity, relatively little is known of the postcranial specializations of the group. Here we describe hindlimb and foot bones of Ourayia uintensis and Chipetaia lamporea that were recovered from the Uinta B member (early Uintan Land Mammal Age), Uinta Formation, Utah. These specimens provi…

The evolutionary context of human economics
Non-human animals are faced with intricate choices demanding rational decisions in order to ensure that they gross energetic and nutritional returns sufficient to cover the costs of movement, predator defense, reproduction, and physiological maintenance. The study of these complex relationships (ecology) is similar in many ways to the study of human economics, and the similarity perhaps reflects underlying common mechanisms relevant to the origin…
Skull of Catopithecus browni, an early tertiary catarrhine
Fossil crania from quarry L-41, Fayum, Egypt, representing Catopithecus browni, a primate similar in size to callitrichids but with a catarrhine dental formula, provide the geologically earliest record of an anthropoidean skull. Catopithecus had postorbital closure developed to the stage seen in extant anthropoideans, with direct contact between zygomatic plate and maxillary tuber, isolating an anterior orbital fissure from the inferior orbital f…

Primate origins
The didelphid Caluromys shows evolutionary convergence towards prosimians in having a relatively large brain, large eyes, small litters, slow development, and agile locomotion. The selection pressures that favored the emergence of primate‐like traits in Caluromys from a generalized didelphid ancestor may be analogous to the selection pressures favoring the initial divergence of primates from a primitive nonprimate ancestor, and thus Caluromys pro…

Cranial morphology of Aegyptopithecus and Tarsius and the question of the tarsier‐anthropoidean clade
New crania of the Oligocene anthropoidean Aegyptopithecus provide a test of the hypothesized tarsier‐anthropoidean clade. Three cranial characters shared by Tarsius and some modern anthropoideans (apical interorbital septum, postorbital septum, “perbullar” carotid pathway) were examined. 1) An apical interorbital septum is absent in Aegyptopithecus . A septum does occur in Galago senegalensis (Lorisidae) and Microcebus murinus (Cheirogaleidae), s…
Scaling of growth and life history traits relative to body size, brain size, and metabolic rate in Lorises and Galagos (Lorisidae, primates)
A broad range of variation in body size, brain size, and metabolic rate occurs within the primate family Lorisidae, thus providing an opportunity to examine the relationship of these three parameters to variation in growth and life history traits. Data on adult body weight, gestation length, lactation length, age at first estrus, litter size, and growth parameters were collected from a captive colony of four lorisid species, Loris tardigradus, Ny…
A new species of Propliopithecus from the Fayum, Egypt
Propliopithecus ankeli is described as a new species of hominoid from the early Oligocene of Egypt. The new species occurs at a stratigraphic level 80 m below quarries yielding P. chirobates and Aegyptopithecus zeuxis. P. ankeli differs from other species of the genus in its large size, relatively robust canines, larger and proportionally broader premolars, and M 1 that has as great or greater mesiodistal length than M 2 . Thus, P. ankeli is char…

Reproduction in the slender loris ( Loris tardigradus malabaricus )
A breeding colony of slender lorises ( Loris tardigradus malabaricus ) was studied to obtain data for comparison with other prosimian species, to contribute reproductive information for improving management of captive lorises, and to resolve some uncertainties in the literature regarding reproduction in the slender loris. At the Duke University Primate Center, a female slender loris reached sexual maturity at approximately ten months of age and c…
