Firing Up the Social Brain

The mastery of fire is a great human achievement which has helped shape our species. This chapter addresses the wider importance of fire, arguing that it is part of a fundamental motor of human evolution, deeply tied into our biology as well as economy and technology, and indeed a motor of the social brain. It seems likely that fire was involved in this nexus from a very early period, probably back to the time of increases in human brain size in the early Pleistocene, and indeed that it may have been a necessity for the subsequent physical evolutionary and social developments in Homo. Fire may be associated so strongly with imagery, imagination and symbolism in the modern world as a result of its primary role in effecting transformation of materials, and acting to link various strands of material culture.

For traditional societies, by which we mean those peoples whose worlds are permeated by kin relations and obligations, and among whom past societies such as those of Neolithic Britain are mostly to be counted, the most precious inheritance is knowledge. Inherited knowledge is of many kinds, the most overt of which is instrumental knowledge—how to make a rope from fibre, where to look for and how to utilize medicinal plants, and so on. Alongside this, however, is a plurality of less obvious but equally fundamental knowledges that include kinds of behavioural knowledge (in the sense of customs and prohibitions, for example), forms of discursive awareness (how to negotiate the social world; what to recall and recount as story and history), and understandings of esoteric beliefs and their concomitant ‘necessary’ actions. Collective cultural and customary knowledge, then, is a resource that makes possible the sustaining and renewal of human social relationships through time. There is a modern tendency to see history as a progression of tableaux, or a montage of scenes, a cavalcade; or, as we noted in Chapter 1, an ascent through measurable social evolutionary stages from relative cultural simplicity towards a present of multilayered complexity. In the modern world, history is expressed in the form of narratives that have been standardized and systematically ordered, and published in a diversity of media, as well as being contested by alternative perspectives in print and online. This contrasts with the way that knowledge and tradition are conveyed in societies that lack written literature, which generally takes the form of oral transmission. However, they are also expressed and fixed (however fleetingly) and transformed through the use of material items and material culture, including the built environment. For such societies, history may take the form of a shared memory of significant events, but these are always experienced and mediated through the filters of social relationships of dominance and subordination, and of kinship. This latter is composed of the shifting elements of genealogy, lineage, and descent, although any or all of these may be fictional in character, and open to a degree of manipulation.

For as long as archaeologists have studied the human past, they have been concerned with the social categories we sometimes call “race.” In this bibliography, I use “race” to indicate a constellation of ideas sharing the assertion that meaningful claims about a person or group can be based on their origins or background, especially relying on their appearance or other physical characteristics. Anthropological research has shown us that when people partition humanity in this way, the results are not meaningful biological units. Race is an ideology of hierarchical, social differentiation masked as embodied differentiation. This is what anthropologists mean when they say that race is a system of social categories that has no basis in biology (see Oxford Bibliographies in Anthropology article Race). Archaeologists are not the only anthropologists who have considered “race” in the human past. Bioarchaeology (see Oxford Bibliographies in Anthropology article Bioarchaeology) and paleoanthropology (see the section “Microevolutionary Issues” in the Oxford Bibliographies in Anthropology article Human Evolution) have also addressed race. These fields examine people’s bodies, for the most part. This bibliography emphasizes archaeology as the study of material culture. “Race” as such has not always featured in archaeological scholarship, but related concepts such as “culture” (when referring to a group of people) and “ethnic group” have long structured archaeology’s understanding of humanity’s past. The archaeological study of “race” is here divided into three arenas: racial difference; racism; and racialization. In reality, these themes cannot be so neatly parsed, but for the purposes of this bibliography racial difference includes sources that address boundary formation and maintenance; racism emphasizes studies concerning inequality; and racialization considers race as a process rather than a state of being.

The first discussion of a relationship between sociality and intelligence came in the middle of the twentieth century, especially by Humphrey who suggested that living socially demanded intellectual abilities above and beyond those required by an animal’s ecology. This led to the Social Intelligence Hypothesis, and then the Machiavellian Intelligence Hypothesis, both proposing that sociality was the main driver of the superior intellect of primates, especially humans. Two key challenges for this hypothesis are that sociality is difficult to quantify and cognition is not well tested by problem solving. More importantly, as data from more species have been examined, the analyses increasingly fail to show that sociality explains variation in brain size, even in primates. I conclude that appealing as this hypothesis is, it does not do a very compelling job of explaining variation in brain size.

It is often the case in interdisciplinary accounts of human evolution that archaeological data are either ignored or treated superficially. This article sets out to redress this position by using archaeological evidence from the last 2.5 million years to test the social brain hypothesis (SBH) – that our social lives drove encephalization. To do this we construct a map of our evolving social complexity that concentrates on two resources – materials and emotions – that lie at the basis of all social interaction. In particular, novel cultural and biological mechanisms are seen as evolutionary responses to problems of cognitive load arising from the need to integrate more individuals and sub-units into the larger communities predicted by the SBH. The Palaeolithic evidence for the amplification of these twin resources into novel social forms is then evaluated. Here the SBH is used to differentiate three temporal movements (2.6–1.6 Ma, 1.5–0.4 Ma and 300–25 ka) and their varied evolutionary responses are described in detail. Attention is drawn to the second movement where there is an apparent disconnect between a rise in encephalization and a stasis in material culture. This disconnect is used to discuss the co-evolutionary relationship that existed between materials and emotions to solve cognitive problems but which, at different times, amplified one resource rather than the other. We conclude that the shape of the Palaeolithic is best conceived as a gradient of change rather than a set of step-like revolutions in society and culture.

ArgumentNeuroscience research has created multiple versions of the human brain. The “social brain” is one version and it is the subject of this paper. Most image-based research in the field of social neuroscience is task-driven: the brain is asked to respond to a cognitive (perceptual) stimulus. The tasks are derived from theories, operational models, and back-stories now circulating in social neuroscience. The social brain comes with a distinctive back-story, an evolutionary history organized around three, interconnected themes: mind-reading, empathy, and the emergence of self-consciousness. This paper focuses on how empathy has been incorporated into the social brain and redefined via parallel research streams, employing a shared, imaging technology. The concluding section describes how these developments can be understood as signaling the emergence of a new version of human nature and the unconscious. My argument is not that empathy in the social brain is a myth, but rather that it is served by a myth consonant with the canons of science.

The social brain hypothesis (SBH) contends that cognitive demands associated with living in cohesive social groups favour the evolution of large brains. Although the correlation between relative brain size and sociality reported in various groups of birds and mammals provides broad empirical support for this hypothesis, it has never been tested in rodents, the largest mammalian order. Here, we test the predictions of the SBH in the ground squirrels from the tribe Marmotini. These rodents exhibit levels of sociality ranging from solitary and single-family female kin groups to egalitarian polygynous harems but feature similar ecologies and life-history traits. We found little support for the association between increase in sociality and increase in relative brain size. Thus, sociality does not drive the evolution of encephalization in this group of rodents, a finding inconsistent with the SBH. However, body mass and absolute brain size increase with sociality. These findings suggest that increased social complexity in the ground squirrels goes hand in hand with larger body mass and brain size, which are tightly coupled to each other.

Archaeological accounts of cognitive evolution have traditionally favoured an internal model of the mind and a search for symbolic proxies. This chapter argues for an external model of cognition and uses this perspective to develop the understanding of Palaeolithic material culture as based on sensory experience. It explores ways of investigating the evolution of cognition by using the social brain model combined with a theory of distributed cognition. The emphasis is on social extension, which was a necessary step to a global distribution and which was achieved by mechanisms such as focused gaze that amplified the emotional content of bonds. The discussion examines the importance of these mechanisms through three aspects of social extension — ontological security, psychological continuity and extension of self.
