The articles in this issue represent the pursuit of a new understanding of the human past, one that can replace the neo-saltationist view of a human revolution with models that can account for the complexities of the archaeological record and of human social lives. The articulation of archaeological, philosophical, and biological perspectives seems to offer a strong foundation for exploring available evidence, and this was the rationale for collecting these particular articles. Even at this preliminary stage there is a coherence (...) emerging in proposals: the origin and operation of symbolically rich, complexly signaling human social systems was the consequence of the long-term evolution of multiple components of perceiving and negotiating social interactions, a contingent outcome of myriad adaptive shifts rather than a single event.

Within paleoanthropology, the origin of behavioral modernity is a famous problem. Very large-brained hominins have lived for around half a million years, yet social lives resembling those known from the ethnographic record appeared perhaps 100,000 years ago. Why did it take 400,000 years for humans to start acting like humans? In this article, I argue that part of the solution is a transition in the economic foundations of cooperation from a relatively undemanding form, to one that imposed much more stress (...) on human motivational and cognitive mechanisms. The rich normative, ceremonial, and ideological lives of humans are a response to this economic revolution in forager lives; from one depending on immediate return mutualism to one depending on delayed and third-party reciprocation.

This article offers some hypotheses to explain Later Stone Age lithic miniaturization: the systematic creation of small stone flakes on the finest-grained materials. Fundamentally, this phenomenon appears to represent the prioritization of stone tool sharpness over longevity, and a disposable mode of using stone tools. Ethnographic evidence from Australasia, the Andaman Islands, and Africa is used to suggest some specific functions for miniaturized lithics, as well as their relationship to other aspects of Later Stone Age material culture, including ochre crayons, (...) shell beads, and notched bones. Miniaturized lithic functions are hypothesized to have a common basis in the cognitive capacity for abstraction: having ideas about ideas. The technological and social affordances of abstraction may have given later Homo sapiens significant adaptive advantages over other members of our genus. (shrink)

This paper examines the inferential framework employed by Palaeolithic cognitive archaeologists, using the work of Wynn and Coolidge as a case study. I begin by distinguishing minimal-capacity inferences from cognitive-transition inferences. Minimal-capacity inferences attempt to infer the cognitive prerequisites required for the production of a technology. Cognitive-transition inferences use transitions in technological complexity to infer transitions in cognitive evolution. I argue that cognitive archaeology has typically used cognitive-transition inferences informed by minimal-capacity inferences, and that this reflects a tendency to favour (...) cognitive explanations for transitions in technological complexity. Next I look at two alternative explanations for transitions in technological complexity: the demographic hypothesis and the environmental hypothesis. This presents us with a dilemma: either reject these alternative explanations or reject traditional cognitive-transition inferences. Rejecting the former is unappealing as there is strong evidence that demographic and environmental influences play some causal role in technological transitions. Rejecting the latter is unappealing as it means abandoning the idea that technological transitions tell us anything about transitions in hominin cognitive evolution. I finish by briefly outlining some conceptual tools from the philosophical literature that might help shed some light on the problem. (shrink)

Music comprises a diverse category of cognitive phenomena that likely represent both the effects of psychological adaptations that are specific to music (e.g., rhythmic entrainment) and the effects of adaptations for non-musical functions (e.g., auditory scene analysis). How did music evolve? Here, we show that prevailing views on the evolution of music – that music is a byproduct of other evolved faculties, evolved for social bonding, or evolved to signal mate quality – are incomplete or wrong. We argue instead that (...) music evolved as a credible signal in at least two contexts: coalitional interactions and infant care. Specifically, we propose that (1) the production and reception of coordinated, entrained rhythmic displays is a co-evolved system for credibly signaling coalition strength, size, and coordination ability; and (2) the production and reception of infant-directed song is a co-evolved system for credibly signaling parental attention to secondarily altricial infants. These proposals, supported by interdisciplinary evidence, suggest that basic features of music, such as melody and rhythm, result from adaptations in the proper domain of human music. The adaptations provide a foundation for the cultural evolution of music in its actual domain, yielding the diversity of musical forms and musical behaviors found worldwide. (shrink)

While the “symbolic” meaning of early body ornamentation has received the lion’s share of attention in the debate on human origins, this paper sets out to explore their aesthetic and agentive dimensions, for the purpose of explaining how various ornamental forms would have led interacting groups to form a cultural identity of their own. To this end, semiotics is integrated with a new paradigm in the archaeology of mind, known as the theory of material engagement. Bridging specifically Peirce’s pragmatic theory (...) and Malafouris’ enactive take on aesthetics allows us to appreciate the formation of aesthetic ideals through the agentive effects of material signs. It is thus proposed that, by attending to the interrelation between form, effect, and affect, members of social groups would have come to appreciate the ways in which their ornamental culture resembles and differs from that of neighbouring groups. Following the Lund conception of cultural semiotics, I argue that models of Ego-culture would have come to evolve along Alter-cultures that also employ ornaments, and against Alius-cultures that have yet to develop or adopt personal decoration. The aesthetic ideals associated with early body ornaments must have therefore played a catalytic role in the formation and communication of group membership. I thus close by proposing that the origins of new cultural identities can be explained by tracing the co-development of ideas and ideals. (shrink)

Research in archaeology and anthropology on the evolution of modern patterns of human behavior often makes use of general theories of signs, usually derived from semiotics. Recent work generalizing David Lewis’ 1969 model of signaling provides a better theory of signs than those currently in use. This approach is based on the coevolution of behaviors of sign production and sign interpretation. I discuss these models and then look at applications to human prehistoric behavior, focusing on body ornamentation, tools, and other (...) artifacts. (shrink)

In evolutionary cognitive archaeology, the school of thought associated with the traditional framework has been deeply influenced by cognitivist intuitions, which have led to the formulation of mentalistic and disembodied cognitive explanations to address the emergence of artifacts within the archaeological record of ancient hominins. Recently, some approaches in this domain have further enforced this view, by arguing that artifacts are passive means to broadcast/perpetuate meanings that are thoroughly internal to the mind. These meanings are conveyed either in the form (...) of a Language of Thought, constituted by sub-personal, content-bearing mental representations, or in that of a natural language. In both cases, however, material culture stands as the physical derivative of computations run over representations, which include abstract concepts, semantic relationships, and meta-representations about intensional states, a conception hereby indicated as “representational apriorism”. In this paper, I will argue that such mentalistic models are plagued by the fundamental problems of content, substance, and origin, which affect the representational substrates required for the production of artifacts. At the same time, these models fail the criterion of minimalism at the crux of conditional cognitive archaeology, because they propose overly costly explanations which are insufficiently constrained by material evidence. An alternative proposal, based on the principles of radical enactive cognitive science, is hereby introduced in order to counter this mentalistic drift. It is concluded that a radical enactive cognitive archaeology is able to dissolve the deep problems confronting the mentalistic paradigm, while providing minimalistic cognitive explanations about the emergence of Paleolithic artifacts.

In the domain of evolutionary cognitive archaeology, the early body ornaments from the Middle Stone Age/Palaeolithic are generally treated as mere by-products of an evolved brain-bound cognitive architecture selected to cope with looming social problems. Such adaptive artefacts are therefore taken to have been but passive means of broadcasting a priori envisaged meanings, essentially playing a neutral role for the human mind. In contrast to this epiphenomenalist view of material culture, postphenomenology and the Material Engagement Theory have been making a (...) case for the active role of artefacts on the count that they can actually shape and restructure the human mind. By bringing these dissenting voices together, the paper at hand employs an enactive way of thinking in order to challenge the epiphenomenalist take on early body ornaments. In fact, two variants of enactivism are presented, each advancing a unique explanation of how the engagement of early humans with body ornaments transformed their minds along the two postphenomenological categories of embodied and hermeneutic cognition. Our theoretical frameworks specifically seek to explore how early beadworks could have scaffolded the creation of semiotic categories and the development of cognitive processes. Despite relying on inherently different premises, both theories suggest that beads fostered the emergence of an epistemic apparatus which thoroughly transformed the way humans engaged with the world. Having concurred on the ornaments’ transformative effects, we ultimately conclude that the epiphenomenalist paradigm best be replaced with an enactive approach grounded on the dictates of postphenomenology and the MET.

Part of the task in studying human evolution is developing a deep understanding of what we share, and do not share, with other life, as a mammal, a primate, a hominin, and as members of the genus Homo. A key aspect of this last facet is gained via the examination of the genus Homo across the Pleistocene. By at least the later Pleistocene members of the genus Homo began to habitually insert shared meaning into and onto their world forming one (...) of the bases of contemporary human abilities to develop a distinctive human niche and human culture. Meaning-laden cultural dynamics constitute the core of a ubiquitous semiotic ecosystem, which in turn structures the architecture of the complex niches and niche construction processes that characterize humanity today. Here, I offer a summary of Pleistocene evolution of the genus Homo and an argument for when and how that extensive and distinctive capacities for shared meaning-making and a particularly dynamic niche construction emerged.

Cognitive archaeologists infer from material remains to the cognitive features of past societies. We characterize cognitive archaeology in terms of trace-based reasoning, which in the case of cognitive archaeology involves inferences drawing upon background theory linking objects from the archaeological record to cognitive features. We analyse such practices, examining work on cognitive evolution, language, and musicality. We argue that the central epistemic challenge for cognitive archaeology is often not a paucity of material remains, but insufficient constraint from cognitive theories. However, (...) we also argue that the success of cognitive archaeology does not necessarily require well-developed cognitive theories: Success might instead lead to them. (shrink)
