On Tools Making Minds: an Archaeological Perspective on Human Cognitive Evolution
However, no flintknapping study has assessed the efficiency of speech alone unassisted by gesture as a tool-making transmission aid. The results provide evidence that gesture was likely to be selected over speech as a teaching aid in the earliest hominin tool-makers; that speech could not have replaced gesturing as a tool-making teaching aid in later hominins, possibly explaining the functional retention of gesturing in the full language of modern humans; and that speech may have evolved for reasons unrelated to tool-making. We conclude that speech is unlikely to have evolved as tool-making teaching aid superior to gesture, as claimed by the technological hypothesis, and therefore alternative views should be considered. For example, gestural language may have evolved to enable tool-making in earlier hominins, while speech may have later emerged as a response to increased trade and more complex inter- and intra-group interactions in Middle Pleistocene ancestors of Neanderthals and Homo sapiens ; or gesture and speech may have evolved in parallel rather than in sequence.
The Oxford Handbook of Language Evolution presents critical accounts of every aspect of the field. Research on language evolution has burgeoned over the last three decades. Interdisciplinary activity has produced fundamental advances in the understanding of language evolution and in human and primate evolution more generally.

Evidence of cultural influences on cognition is accumulating, but untangling these cultural influences from one another or from non-cultural influences has remained a challenging task. As between-group differences are neither a sufficient nor a necessary indicator of cultural impact, cross-cultural comparisons in isolation are unable to furnish any cogent conclusions. This shortfall can be compensated by taking a diachronic perspective that focuses on the role of culture for the emergence and evolution of our cognitive abilities. While these strategies are reliant on our understanding of present-day cognition, they conversely also have the potential to advance this understanding in fundamental ways. Human cognition is profoundly shaped by culture. This is perhaps more evident for some domains than for others, but striking examples abound: orientation in and referencing to space and time Levinson, ; Haun et al. As much as they are rendered possible by endowed capacities, all of these cognitive abilities, activities, and achievements are also predicated on culture, be it by way of culturally accumulated and transmitted knowledge, culture-specific concepts and framework theories, cultural tools, conventions, and practices, or simply by the fact that we are a cultural species Tomasello et al.
