As our closest living relatives, chimpanzees and bonobos have been widely used as models of the behavior of early hominids. In recent years, as information on the social behavior and ecology of bonobos has come to light, many interspecific comparisons have been made. Chimpanzees have been characterized in terms of their intercommunity warfare, meat eating, infanticide, cannibalism, male status‐striving, and dominance over females. Bonobos, meanwhile, have been portrayed as the “Make love, not… Expand
Bonobo but not chimpanzee infants use socio-sexual contact with peers
It is suggested that the socio-sexual behavior previously observed in various captive and wild bonobos is species-typical, and wild-born bonobos originating from a large geographical range develop this behavior long before puberty and without the need for adults initiating such behavior or acting as models for observational learning. Expand
The Chimpanzee Has No Clothes
Chimpanzee referential models for early hominid behavior have become the most common of all current approaches. In addition to chimpanzees’ close evolutionary relationship to humans, theExpand
Differences between chimpanzees and bonobos in neural systems supporting social cognition.
It is suggested that this neural system not only supports increased empathic sensitivity in bonobos, but also behaviors like sex and play that serve to dissipate tension, thereby limiting distress and anxiety to levels conducive with prosocial behavior. Expand
A comparison of bonobo and chimpanzee tool use: evidence for a female bias in the Pan lineage
It is shown that captive bonobos and chimpanzees are equally diverse tool-users in most contexts, and that female bonobos displayed a larger range of tool use behaviours than males, a pattern previously described for chimpanzees but not for other great apes. Expand
‘Friendship’ for fitness in chimpanzees?
This proposal that primates trade social services for fitness benefits in their relationships with the opposite sex is tested in a colony of captive chimpanzees by examining behavioural data on grooming, agonistic support and food sharing in relation to genetically established paternity. Expand
The Other “Closest Living Relative”: How Bonobos (Pan paniscus) Challenge Traditional Assumptions about Females, Dominance, Intra‐ and Intersexual Interactions, and Hominid Evolution
The bonobo evidence suggests that models of human evolution must be reformulated such that they also accommodate real and meaningful female bonds; the possibility of systematic female dominance over males; female mating strategies which encompass extra‐group paternities; hunting and meat distribution by females; the importance of the sharing of plant foods; affinitive inter‐community interactions.

Chimpanzees and the Behavior of Ardipithecus ramidus
It is argued that the Ardipithecus fossils strongly support a chimpanzee model for early hominin behavioral ecology, and how paleoanthropologists may more realistically extrapolate from living apes to extinct hominoid behavior and ecology is suggested. Expand
Female Coalitions Against Male Aggression in Wild Chimpanzees of the Budongo Forest
During a study of male and female aggressive interactions among chimpanzees of the Budongo Forest, Uganda, wild adult female chimpanzees sometimes formed coalitions with one another to retaliate against male aggression, strengthening the argument that at least some of the differences between chimpanzees and bonobos may be more of degree than of kind. Expand
Female Bonds and Kinship in Forest Guenons
A comparative study on the genetic and social organization of two sympatric forest guenons, Diana and Campbell’s monkeys, found that both formed female-bonded, egalitarian social organizations and found that females consistently targeted individuals other than their closest relatives to form social bonds.

Ecological variation in cognition: Insights from bonobos and chimpanzees
One of the most pressing problems for the comparative study of cognition is explaining the emergence of variation in psychological abilities across species. How and why do such differences inExpand
