Many animals exhibit social learning and behavioural traditions, but human culture exhibits unparalleled complexity and diversity, and is unambiguously cumulative in character. These similarities and differences have spawned a debate over whether animal traditions and human culture are reliant on homologous or analogous psychological processes. Human cumulative culture combines high‐fidelity transmission of cultural knowledge with beneficial modifications to generate a ‘ratcheting’ in… 
Cognition and Culture in Evolutionary Context
The main contributions of this approach to the science of culture are its emphasis on the integration of information on mechanisms, function, and evolution, and on mechanistic factors located at different levels of the biological hierarchy.
Evolutionary neuroscience of cumulative culture
This approach reconciles currently competing accounts of the origins of human culture and develops the concept of a uniquely human technological niche rooted in a shared primate heritage of visuomotor coordination and dexterous manipulation.
Primate Cognition and the Origins of Human Culture

Evidence that non-human primates indeed do have culture is presented, and several factors which might account for the relative sophistication of human culture are considered: Learning, the ratchet effect, conformity, collaboration, meta-representation, and imagination.

All the while, the traditional social sciences have remained steadfastly unwilling to accept that evolutionary approaches to human behaviour have any merit or relevance, and indeed have abandoned the scientific method in favour of more politically motivated interpretive methods.
Teaching and curiosity: sequential drivers of cumulative cultural evolution in the hominin lineage
It is suggested that the best explanation for culture began to be truly cumulative around 500,000 years ago is the emergence of verbal teaching, which not only requires language and thus probably coevolved with the latter’s evolution but also reflects the overall increase in proactive cooperation due to extensive allomaternal care.
Acquisition of a socially learned tool use sequence in chimpanzees: Implications for cumulative culture.
All Innovations are Equal, but Some More than Others: (Re)integrating Modification Processes to the Origins of Cumulative Culture
It is argued that a possible impediment for cumulative culture in nonhuman animals may in fact reside not so much in the fidelity of their social transmission but rather in the constraints, internal and external, on their capacity to modify complex, hierarchically structured cultural recipes.
Cumulative culture in nonhumans: overlooked findings from Japanese monkeys?
The reassessment of the Koshima ethnography is preliminary and nonquantitative, but it raises the possibility that cumulative culture, at least in a simple form, occurs spontaneously and adaptively in other primates and nonhumans in nature.


Transmission fidelity is the key to the build-up of cumulative culture

The findings support the idea that high-fidelity transmission is the key driver of human cumulative culture, and that progress in cumulative culture depends more on trait combination than novel invention or trait modification.
Ratcheting up the ratchet: on the evolution of cumulative culture
This work argues that chimpanzee cultural traditions represent behavioural biases of different populations, all within the species’ existing cognitive repertoire that are generated by founder effects, individual learning and mostly product-oriented (rather than process-oriented) copying.
The evolution of animal ‘cultures’ and social intelligence
Decades-long field research has flowered into integrative studies that, together with experimental evidence for the requisite social learning capacities, have indicated a reliance on multiple
‘ Cultured monkeys , social learning cast in stones ’ Cultured Monkeys
Sixty years ago, the notion that animals could have culture was unthinkable to most behavioral scientists. Today, evidence for innovation, transmission, acquisition, long-term maintenance, and
Social Learning Mechanisms and Cumulative Cultural Evolution
It is concluded that accounts of the unusual complexity of human culture in terms of species-unique learning mechanisms do not currently provide complete explanations and that other factors may be involved.
Identification of the Social and Cognitive Processes Underlying Human Cumulative Culture
The success of the children, but not of the chimpanzees or capuchins, in reaching higher-level solutions was strongly associated with a package of sociocognitive processes—including teaching through verbal instruction, imitation, and prosociality—that were observed only in the children and covaried with performance.
Chimpanzees (Pan troglodytes) and the question of cumulative culture: an experimental approach
It is tentatively concluded that young chimpanzees exhibit a tendency to become ‘stuck’ on a technique they initially learn, inhibiting cumulative social learning and possibly constraining the species’ capacity for cumulative cultural evolution.
Population size predicts technological complexity in Oceania

It is shown that in Oceania, around the time of early European contact, islands with small populations had less complicated marine foraging technology, suggesting that demography plays an important role in generating cumulative cultural adaptation.
Why Culture is Common, but Cultural Evolution is Rare
Two models of the evolution of psychological capacities that allow cumulative cultural evolution are analyzed, suggesting why such capacities may be rare in nature.
