The discovery of the earliest known stone tools at Lomekwi 3 (LOM3) from West Turkana, Kenya, dated to 3.3 Ma, raises new questions about the mode and tempo of key adaptations in the hominin lineage. The LOM3 tools date to before the earliest known fossils attributed to Homo at 2.8 Ma. They were made and deposited in a more C 3 environment than were the earliest Oldowan tools at 2.6 Ma. Their discovery leads to renewed investigation on the timing of the emergence of human-like manipulative capabilities in early hominins and implications for reconstructing cognition. The LOM3 artefacts form part of an emerging paradigm shift in palaeoanthropology, in which: tool-use and tool-making behaviours are not limited to the genus Homo ; cranial, post-cranial and behavioural diversity in early Homo is much wider than previously thought; and these evolutionary changes may not have been direct adaptations to living in savannah grassland environments. This article is part of the themed issue ‘Major transitions in human evolution'.

ABSTRACTHabitual reliance on tool use is a marked behavioral difference between wild robust (genus Sapajus) and gracile (genus Cebus) capuchin monkeys. Despite being well studied and having a rich repertoire of social and extractive foraging traditions, Cebus sp have rarely been observed engaging in tool use and have never been reported to use stone tools. In contrast, habitual tool use and stone-tool use by Sapajus is widespread. We discuss factors which might explain these differences in patterns of tool use between Cebus and Sapajus. We then report the first case of habitual stone-tool use in a gracile capuchin: a population of white-faced capuchins (Cebus capucinus imitator) in Coiba National Park, Panama who habitually rely on hammerstone and anvil tool use to access structurally protected food items in coastal areas including Terminalia catappa seeds, hermit crabs, marine snails, terrestrial crabs, and other items. This behavior has persisted on one island in Coiba National Park since at least 2004. From one year of camera trapping, we found that stone tool use is strongly male-biased. Of the 205 unique camera-trap-days where tool use was recorded, adult females were never observed to use stone-tools, although they were frequently recorded at the sites and engaged in scrounging behavior. Stone-tool use occurs year-round in this population, and over half of all identifiable individuals were observed participating. At the most active tool use site, 83.2% of days where capuchins were sighted corresponded with tool use. Capuchins inhabiting the Coiba archipelago are highly terrestrial, under decreased predation pressure and potentially experience resource limitation compared to mainland populations– three conditions considered important for the evolution of stone tool use. White-faced capuchin tool use in Coiba National Park thus offers unique opportunities to explore the ecological drivers and evolutionary underpinnings of stone tool use in a comparative within- and between-species context.

Tool Technology

Tom Wynn’s original work that looked at the evolution of stone tool technology using Piaget’s developmental sequence was the beginning of productive research into the evolution of hominin and human cognition. In this chapter, I evaluate those beginnings and discusses recent attempts to provide a more satisfactory understanding of changes in stone tool technologies, including work by Philip Barnard and William McGrew, subsequent work by Tom Wynn, and my own work with various collaborators. It suggests that some of the previous understandings of cognitive evolution were shaped by the fact that approaches to stone tools were largely determined in the nineteenth century. I propose some new ways of looking at stone tools and the sort of story that allows for more productive models of the evolution of human cognition.

Despite being well studied and having a rich repertoire of social and extractive foraging traditions, Cebus sp. rarely use tools and have never been observed using stone tools.

Dual Inheritance

One of the greatest difficulties with evolutionary approaches in the study of stone tools (lithics) has been finding a mechanism for tying culture and biology in a way that preserves human agency and operates at scales that are visible in the archaeological record. The concept of niche construction, whereby organisms actively construct their environments and change the conditions for selection, could provide a solution to this problem. In this review, we evaluate the utility of niche construction theory (NCT) for stone tool archaeology. We apply NCT to lithics both as part of the ‘extended phenotype’ and as residuals or precipitates of other niche-constructing activities, suggesting ways in which archaeologists can employ niche construction feedbacks to generate testable hypotheses about stone tool use. Finally, we compare NCT to other prominent evolutionary approaches, such as human behavioral ecology and dual-inheritance theory, concluding that NCT has several advantages.

Long-standing speculations and more recent hypotheses propose a variety of possible evolutionary connections between language, gesture and tool use. These arguments have received important new support from neuroscientific research on praxis, observational action understanding and vocal language demonstrating substantial functional/anatomical overlap between these behaviours. However, valid reasons for scepticism remain as well as substantial differences in detail between alternative evolutionary hypotheses. Here, we review the current status of alternative ‘gestural’ and ‘technological’ hypotheses of language origins, drawing on current evidence of the neural bases of speech and tool use generally, and on recent studies of the neural correlates of Palaeolithic technology specifically.

Out Of Africa

In the 13 years since ‘Problems in the Stone Age of Southeast Asia’ was published, there has been a number of significant developments. There remains a lack of early cultural material despite the possibility that first occupation of the area may date back as far as 1.8 Myrs. It seems that the first hominins in the region were essentially ‘alithic’ in their adaptation, making the reconstruction of their behaviour extremely difficult. There is also a question as to which hominin was first ‘Out of Africa’ and into Asia and a suggestion that Homo erectus is, in fact, an Asian species that may have migrated west. This has important implications for interpretations of the significance of the so-called ‘Movius Line’. By the time stone tool use does appear regularly in the record, modern humans are present but it is still hard to identify the kinds of directional changes that are associated with the Late Pleistocene elsewhere in the world. The question of when humans were able to exploit tropical forests in the region is also one that recent work explores. The recent discoveries from Flores of stone tools that appear to pre-date the arrival of modern humans, and a possibly associated ‘dwarf’ hominin, Homo floresiensis, all require re-appraisal of the nature of human activity in the region.

Early Stone Age

Stone tools in the prehistoric record are the most abundant source of evidence for understanding early hominin technological and cultural variation. The field of primate archaeology is well placed to improve our scientific knowledge by using the tool behaviours of living primates as models to test hypotheses related to the adoption of tools by early stone-age hominins. Previously we have shown that diversity in stone tool behaviour between neighbouring groups of long-tailed macaques (Macaca-fascicularis) could be explained by ecological and environmental circumstances (Luncz et al., 2017b). Here however, we report archaeological evidence, which shows that the selection and reuse of tools cannot entirely be explained by ecological diversity. These results suggest that tool-use may develop differently within species of old-world monkeys, and that the evidence of material culture can differ within the same timeframe at local geographic scales and in spite of shared environmental and ecological settings.

Behavioural Diversity

Abstract Large brains and behavioural innovation are positively correlated, species-specific traits, associated with the behavioural flexibility animals need for adapting to seasonal and unpredictable habitats. Similar ecological challenges would have been important drivers throughout human evolution. However, studies examining the influence of environmental variability on within-species behavioural diversity are lacking despite the critical assumption that population diversification precedes genetic divergence and speciation. Here, using a dataset of 144 wild chimpanzee (Pan troglodytes) communities, we show that chimpanzees exhibit greater behavioural diversity in environments with more variability — in both recent and historical timescales. Notably, distance from Pleistocene forest refugia is associated with the presence of a larger number of behavioural traits, including both tool and non-tool use behaviours. Since more than half of the behaviours investigated are also likely to be cultural, we suggest that environmental variability was a critical evolutionary force promoting the behavioural, as well as cultural diversification of great apes.

Shed Light

This article tries to shed light on the mystery of human culture. Human beings are the only extant species with cumulative, evolving cultures. Many animal species do have cultural traditions in the form of socially transmitted practices but they typically lack cumulative culture. Why is that? This discrepancy between humans and animals is even more puzzling if one realizes that culture seems highly advantageous. Thanks to their accumulated knowledge and techniques our early ancestors were able to leave their cradle in Africa and swarm out across the planet, thereby adjusting themselves to a whole range of new environments. Without culture this would have been impossible. So we may ask once again: if cumulative culture is so useful, why don’t other animals have it? In order to explain this mystery I won’t appeal to the major transitions in human evolution—like walking upright, crafting stone tools and controlling fire, etc.,—because that would be question begging. Instead I try to unearth the mechanisms that caused those evolutionary turning points to occur in the first place. It seems that unlike other animals, humans are predisposed to efficiently acquire, store and transmit cultural information in such ways that our cultures can genuinely evolve.
