Generation times in wild chimpanzees and gorillas suggest earlier divergence times in great ape and human evolution
Fossils and molecular data are two independent sources of information that should in principle provide consistent inferences of when evolutionary lineages diverged. Here we use an alternativeExpand

The limited impact of kinship on cooperation in wild chimpanzees
The complex cooperative behavior exhibited by wild chimpanzees generates considerable theoretical and empirical interest, yet we know very little about the mechanisms responsible for its evolution.Expand

Kinship and social bonds in female chimpanzees (Pan troglodytes)
A large body of theoretical and empirical research suggests that kinship influences the development and maintenance of social bonds among group‐living female mammals, and that human females may beExpand

Food sharing is linked to urinary oxytocin levels and bonding in related and unrelated wild chimpanzees
Humans excel in cooperative exchanges between unrelated individuals. Although this trait is fundamental to the success of our species, its evolution and mechanisms are poorly understood. Other socialExpand

Urinary oxytocin and social bonding in related and unrelated wild chimpanzees
Animals that maintain cooperative relationships show gains in longevity and offspring survival. However, little is known about the cognitive or hormonal mechanisms involved in cooperation. Indeed,Expand

Genetic and ‘cultural’ similarity in wild chimpanzees
The question of whether animals possess ‘cultures’ or ‘traditions’ continues to generate widespread theoretical and empirical interest. Studies of wild chimpanzees have featured prominently in thisExpand

Chimpanzee genomic diversity reveals ancient admixture with bonobos
Of chimpanzees and bonobos Modern non-African human genomes contain genomic remnants that suggest that there was interbreeding between ancient humans and archaic hominoid lineages. Now, de Manuel etExpand

Social support reduces stress hormone levels in wild chimpanzees across stressful events and everyday affiliations
Stress is a major cause of poor health and mortality in humans and other social mammals. Close social bonds buffer stress, however much of the underlying physiological mechanism remains unknown.Expand

The Genetic Signature of Sex-Biased Migration in Patrilocal Chimpanzees and Humans
A large body of theoretical work suggests that analyses of variation at the maternally inherited mitochondrial (mt)DNA and the paternally inherited non-recombining portion of the Y chromosome (NRY)Expand

Favorable ecological circumstances promote life expectancy in chimpanzees similar to that of human hunter-gatherers.
Demographic data on wild chimpanzees are crucial for understanding the evolution of chimpanzee and hominin life histories, but most data come from populations affected by disease outbreaks andExpand
