Humans acquire far more of their behaviour from conspecifics via culture than any other species. Our culture is larger because it accumulates, where other species' seem to stay approximately the same size (Tomasello, 1999). This chapter attempts to clarify the problem of cultural accumulation by distinguishing between the site of a culture that can be transmitted from one generation, and the extent of culture transmitted. A culture's size is determined largely by ecological constraints, and… 
Studies in the Philosophy of Sociality
Our aim in this chapter is to delineate the form of shared agency that we take to be manifested in collective memory. We argue for two theses. First, we argue that, given a relatively weak conception
Animal social learning: associations and adaptations

TLDR
Current evidence suggests that much social learning may be based on ‘ordinary’ processes but with extraordinary consequences, and empirical work is required to uncover the mechanisms involved and their impact on the efficacy of social learning.

TLDR
The role and sources of innovation in generating culture, and also the role of norms in preserving it are discussed, and a model of cultural evolution exploring the problem of cultural stability and change is demonstrated.
Crude, Cheesy, Second-Rate Consciousness
If we aren’t sure what consciousness is, how can we be sure we haven’t already built it? In this article I speak from the perspective of someone who routinely builds small-scale machine intelligence.

Representations underlying social learning and cultural evolution
TLDR
This article discusses the potential computational properties of social learning, then examines the phenomenon in nature through creating a taxonomy of the representations that might underly it, and discusses theoretical limits on cultural evolution.
Embodiment versus memetics
TLDR
The theory of memetics is linked to the established literature on semantic space, the extent to which these memetic mechanisms might account for language independently of embodiment is examined, and the evolution of language through uniquely human cognitive capacities is explained.
Iterated learning and the cultural ratchet
TLDR
A simple model is used to characterize the con- ditions necessary for this accrual of knowledge, and compare the predic- tions of this model to experimental results, which suggest that these changes will accumulate if learners have access to the actual beliefs of their teachers, as opposed to merely observations of behavior informed by those beliefs.
An examination of the role of prestige in cultural evolution with the aid of Agent Based Modelling
Current research shows that natural selection favours evolved capacities in distinguishing the most successful individuals and copying the skills, beliefs and behaviours that contribute to their
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.
Agent Based Modelling of Communication Costs: Why Information Can Be Free
What purposes, other than facilitating the sharing of information, can language have served? First, it may not have evolved to serve any purpose at all. It is possible that language is just a side
Orangutan Cultures and the Evolution of Material Culture
TLDR
A correlation between geographic distance and cultural difference, a correlation between the abundance of opportunities for social learning and the size of the local cultural repertoire, and no effect of habitat on the content of culture mean that great-ape cultures exist and may have done so for at least 14 million years.
Embodiment vs. Memetics: Does Language Need a Physical Plant?
Although the embodied approach to AI has lead to a large number of advances in the field, there has been no convincing demonstration of one of its earliest promises: that it would solve semantic

TLDR
Research in the field and laboratory shows that sophisticated social cognition underlies social behavior in primate groups and a growing body of evidence suggests that the quality of social relationships has measurable fitness consequences for individuals.
