Primate Play and the Classificatory Making of Human Nature
Primate play is often interpreted as a developmental activity through which immature individuals acquire capacities used later in life. This essay uses play to examine a wider process in behavioral research: how classification helps produce behavioral data and shapes the explanations those data can support. It asks how juvenile actions are classified as play and become evidence for claims about development, evolution, and “human nature.” I argue …
Forms, Patterns, and Predictors of Body Contact Between Mothers and Infants in Ngogo Chimpanzees ( Pan troglodytes schweinfurthii )
Physical contact between mothers and infants is a cornerstone of infant care in primates, providing protection, thermoregulation, and transportation. While previous studies have focused primarily on ventro‐ventral and dorso‐ventral contact, the diversity of body contact forms and their developmental trajectories remains underexplored. We examined how infant age, sex, maternal parity, and group size influence mother–infant body contact in 37 chimp…
Male Sexual Coercion During Mating and Infanticide Risk Increase Self-directed Behaviors in Female Black-and-White Colobus (Colobus vellerosus)
Investigating infant feeding development in wild chimpanzees using stable isotopes of naturally shed hair
Measuring the relative contributions of milk and non‐milk foods in the diets of primate infants is difficult from observations. Stable carbon (δ 13 C) and nitrogen (δ 15 N) isotopes in hair can be used to physiologically track infant feeding through development, but few wild studies have done so, likely due to the difficulty in collecting hair non‐invasively. We assessed infant feeding at different ages in wild chimpanzees ( Pan troglodytes ) at …
Developmental and Sex‐Based Variation in Nest Building Among Wild Immature Chimpanzees
All great apes build nests. Nests in trees or on the ground provide apes with a safe and comfortable place to sleep and rest at night and during the day. Nest building is a necessary skill and form of tool use that individuals learn and practice early in life, but little is known about its development and about the factors affecting the expression of nest building in infancy. We studied the development of daytime nest building of 72 wild immature…
High levels of infant handling by adult males in Rwenzori Angolan colobus (Colobus angolensis ruwenzorii) compared to two closely related species, C. guereza and C. vellerosus
Premasticated food transfer by wild chimpanzee mothers with their infants: Effects of maternal parity, infant age and sex, and food properties
The influence of male takeovers on female dispersal in Colobus vellerosus
Male takeovers affect male tenure, female mate choice and ultimately, individual reproductive success in group-living primates. In social systems with female philopatry and high male reproductive skew, male takeovers largely determine female mate choice, whereas in species with female dispersal, females have the option of deserting a new male. We focused on a species with facultative female dispersal to investigate which factors promote female de…
A novel fecal stable isotope approach to determine the timing of age‐related feeding transitions in wild infant chimpanzees
Our results resemble the stable isotope differences of human babies. This study contributes to a model of chimpanzee nutritional development required to understand early life history patterns in hominins
Female parity, maternal kinship, infant age and sex influence natal attraction and infant handling in a wild colobine ( Colobus vellerosus )
Primate females often inspect, touch and groom others' infants (natal attraction) and they may hold and carry these infants in a manner resembling maternal care (infant handling). While natal attraction and infant handling occur in most wild colobines, little is known about the factors influencing the expression of these behaviors. We examined the effects of female parity, kinship, and dominance rank, as well as infant age and sex in wild Colobus…
