Percussive tool use holds special interest for scientists concerned with human origins. We
summarize the findings from two field sites, Taï and Fazenda Boa Vista, where percussive …

Highlights•Tool use is habitual in several capuchins populations and is a valuable source of
information about physical cognition.-Those studies are on the rise and are a source of …

The study of the archaeological remains of fossil hominins must rely on reconstructions to
elucidate the behaviour that may have resulted in particular stone tools and their …

Our understanding of the emergence of technology shapes how we view the origins of
humanity,. Sharp-edged stone flakes, struck from larger cores, are the primary evidence for …

The human archaeological record changes over time. Finding such change in other animals
requires similar evidence, namely, a long-term sequence of material culture. Here, we apply …

Here we examine data from a two-year research on the use of sticks as probes by two
groups of wild capuchin monkeys (Sapajus libidinosus) in Serra da Capivara National Park …

Animals foraging in their natural environments need to be proficient at recognizing and
responding to changes in food targets that affect accessibility or pose a risk. Wild bearded …

The use of pounding stone tools (PSTs) is a customary behaviour in several wild
populations of capuchin monkeys; most of these monkeys use PSTs primarily to open hard …

Robust capuchin monkeys (Sapajus) are known for processing mechanically challenging
foods, having morphological adaptations to do so. However, several populations go beyond …

Humans' daily life is dominated by, and depends on, the use of tools. Because we are so
skilled at using tools, and attribute a pivotal role in human evolution to tool use, the …
