“…As discussed above, it is worth keeping in mind that chimpanzees (or bonobos such as Kanzi) somehow fall short in being able to visualize the properties of the core so as to exploit them to produce flakes [54,55]. A functional imaging study of brain regions activated in human subjects by physical reasoning in nut-cracking versus stoneflaking tasks would elucidate this problem, but to our knowledge, no such study has yet been conducted.…”

Various authors have suggested behavioural similarities between tool use in early hominins and chimpanzee nut cracking, where nut cracking might be interpreted as a precursor of more complex stone flaking. In this paper, we bring together and review two separate strands of research on chimpanzee and human tool use and cognitive abilities. Firstly, and in the greatest detail, we review our recent experimental work on behavioural organization and skill acquisition in nut-cracking and stoneknapping tasks, highlighting similarities and differences between the two tasks that may be informative for the interpretation of stone tools in the early archaeological record. Secondly, and more briefly, we outline a model of the comparative neuropsychology of primate tool use and discuss recent descriptive anatomical and statistical analyses of anthropoid primate brain evolution, focusing on corticocerebellar systems. By juxtaposing these two strands of research, we are able to identify unsolved problems that can usefully be addressed by future research in each of these two research areas.

“…The same is true for bonobo chimpanzee (P. paniscus) populations that also consume meat (Hohmann and Fruth, 2008). This lack of tool-assisted butchery cannot easily be attributed to a physical inability to produce or utilise stone flakes suitable for cutting (Wynn and McGrew, 1989;Toth et al, 1993;Schick et al, 1999;Mercader et al, 2002;Toth and Schick, 2009), but rather, it seems that there is a lack of incentive for this behavioural repertoire to naturally occur. Indeed, chimpanzee meat eating is characterised by the consumption of small-bodied vertebrates that can readily be dismembered through the bare force of hands and teeth (Boesch, 1994;McGrew, 1992;Stanford, 1996;Newton-Fisher, 2014;Marzke et al, 2015).…”

with cutting efficiency using both flakes and handaxes over extended periods of use and in multiple types of cutting task. Results indicate that (1) both handaxe and flake cutting efficiency is significantly related with biometric variation of individual tool-users, (2) relationships between biometric parameters and efficiency are consistent across extended durations but vary dependent upon task-type conditions, (3) manipulative strength is the most significant biometric trait in terms of predicting flake efficiency, while (4) hand size is the strongest predictor of handaxe cutting efficiency. These results demonstrate the long-term impact that stone tool use likely had on the evolution of hominin biometric variation during the Lower Palaeolithic, while also highlighting the variable influence of different tool use contexts.Most notably, results indicate that the onset of the Acheulean may have been dependent, a priori, upon hand dimensions that are close to the modern human range, and that prior to the appearance of this anatomy, handaxe use would have been an impractical (i.e. inefficient) tool use behaviour compared to the use of flakes.

“…In spite of being the result of autonomously evolved lineages (Gibbons 2009), the great apes have been studied with a view to establishing a kind of baseline ability from whence hominins evolved (Savage-Rumbaugh 1986, Savage-Rumbaugh & Lewin 1994, Toth et al 1993, Gowlett 2009, Whiten et al 2009). …”
