There is increasing evidence for cultural variations in behaviour among non-human species, but human societies additionally display elaborate cumulative cultural evolution, with successive generations building on earlier achievements. Evidence for cumulative culture in non-human species remains minimal and controversial. Relevant experiments are also lacking. Here we present a first experiment designed to examine chimpanzees’ capacity for cumulative social learning. Eleven young chimpanzees… 
Basis for Cumulative Cultural Evolution in Chimpanzees: Social Learning of a More Efficient Tool-Use Technique
TLDR
This study presents the first experimental evidence for chimpanzees' social transmission of a more efficient tool-use technique invented by a conspecific group member, and provides important insights into the cognitive basis for cumulative culture in chimpanzees, and suggests possible conditions in which cumulative cultural evolution could arise even in non-human animals.
Acquisition of a socially learned tool use sequence in chimpanzees: Implications for cumulative culture.
Collective knowledge and the dynamics of culture in chimpanzees
TLDR
Exposing small communities of chimpanzees to contexts incorporating increasingly challenging, but more rewarding tool use opportunities revealed solutions arising through the combination of different individuals' discoveries, spreading to become shared innovations.
The context of behavioural flexibility in chimpanzees (Pan troglodytes) : implications for the evolution of cumulative culture
TLDR
It is proposed that conservatism is linked to behavioural complexity, potentially mediated by cognitive resource availability, and may be an important factor in the evolution of cumulative culture.
Chimpanzees prioritise social information over pre-existing behaviours in a group context but not in dyads
TLDR
It is argued that an important influence of social context upon prioritisation of social information over pre-existing methods, which can result in group homogeneity of behaviour, is demonstrated.
The scope of culture in chimpanzees, humans and ancestral apes
  • A. Whiten
  • Biology, Psychology
    Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2011
TLDR
Analysis of the features shared by chimpanzees and humans is used to infer the scope of cultural phenomena in the authors' last common ancestor, at the same time clarifying the nature of the special characteristics that advanced further in the hominin line.
Social Learning and Culture in Child and Chimpanzee.
  • A. Whiten
  • Biology, Psychology
    Annual review of psychology
  • 2017
TLDR
Field and experimental studies, particularly those in which direct chimpanzee-child comparisons have been made, delineate a growing set of commonalities between the phenomena of social learning and culture in the lives of chimpanzees and humans.
Conservatism and “copy-if-better” in chimpanzees (Pan troglodytes)
TLDR
Whether chimpanzees employ copy-if-better in a simple token-exchange paradigm controlling for individual and random social learning is investigated and the validity of the results is discussed by considering alternative explanations and related to the emergence of cumulative culture.
Skill mastery inhibits adoption of observed alternative solutions among chimpanzees (Pan troglodytes)
TLDR
It is concluded that innovators stimulate others to experiment with the solutions they display, but that chimpanzees are nevertheless conservative; mastery of a skill inhibits further exploration, and hence adoption of alternative techniques even if these are more efficient.

Conformity to cultural norms of tool use in chimpanzees
TLDR
It is shown that experimentally introduced technologies will spread within different ape communities, and a subset of chimpanzees that discovered the alternative method nevertheless went on to match the predominant approach of their companions, showing a conformity bias that is regarded as a hallmark of human culture.
Cultures in chimpanzees
TLDR
It is found that 39 different behaviour patterns, including tool usage, grooming and courtship behaviours, are customary or habitual in some communities but are absent in others where ecological explanations have been discounted.
Spread of arbitrary conventions among chimpanzees: a controlled experiment
TLDR
This work seeded one of two rewarded alternative endpoints to a complex sequence of behaviour in each of two chimpanzee groups, and each sequence spread in the group in which it was seeded, with many individuals unambiguously adopting the sequence demonstrated by a group member.
Innovation in wild chimpanzees (Pan troglodytes)
  • C. Boesch
  • Biology, Psychology
    International Journal of Primatology

TLDR
The chimpanzees of the Taï National Park, Côte d’Ivoire, spontaneously included new patterns of behavior in their repertoire during this study, and leaf- grooming acquired a new function in Gombe chimpanzees.
The emergence of cultures among wild chimpanzees.
TLDR
It is shown that social canalization, including imitation, is important in explaining the acquisition of nut-craking behaviour in wild chimpanzees and argued that a culture requires not only a social learning process to produce a faithful transmission of information, but also a mechanism that guarantees the permanence of the information between transmission events.
Cultural innovation and transmission of tool use in wild chimpanzees: evidence from field experiments
TLDR
Evidence from three complementary approaches in a group of oil-palm nut- (Elaeis guineensis) cracking chimpanzees at Bossou, Guinea demonstrates a mechanism for the emergence of culture in wild chimpanzees.
CHARTING CULTURAL VARIATION IN CHIMPANZEES
Cultural variation among chimpanzee communities or unit-groups at nine long-term study sites was charted through a systematic, collaborative procedure in which the directors of the sites first agreed
Social tradition and the use of tool‐composites by wild chimpanzees
TLDR
Use of more than one kind of tool for a single task, a tool‐composite, by wild chimpanzees (Pan troglydytes) demonstrates high intelligence and motor control which requires foresight, understanding of relations among tools and task, and behavioral coordination.
Ant‐dipping among the chimpanzees of Bossou, Guinea, and some comparisons with other sites
TLDR
Observations suggest a strong influence of prey characteristics, including aggressiveness and/or gregariousness, on tool length and technique employed by the chimpanzees of Bossou, in southeastern Guinea, West Africa.
Cultural transmission in the tool use and communicatory signaling of chimpanzees
TLDR
Not all population differences are cultural in origin: For example, naturalistic observations have revealed that one population of wild rats dives into the Po River for mollusks, whereas another population of rats living on that same river does not.
