“…Several authors have hypothesized that the destructive foraging habits of capuchins underlie their tool-using and toolmaking abilities (Parker and Gibson, 1977;Westergaard and Fragaszy, 1987). Wild capuchins use tools at least occasionally (Boinski, 1988;Chevalier-Skolnikoff, 1990;Fernandes, 1991), and we speculate that capuchins may produce and use stone tools within their New World habitat.…”

We examined the production of stone tools by capuchins (Cebus apella). Eleven subjects used five reduction techniques to produce 346 stone tools (48 cores and 298 flakes). They produced a sharp edge on 83% of the cores and largest flakes. Three monkeys later used a sample of these objects as cutting tools. These results demonstrate that monkeys produce lithic tools analogous to those produced by Oldowan hominids.

“…Instances of tool use that have been observed among wild capuchins include clubbing a snake with a stick and cracking open an oyster with a shell (Boinski, 1988;Fernandes, 1991). In captivity capuchins use stones as pounding and cutting tools and as throwing implements (Westergaard and Suomi, 1994a-c).…”

“…For example, wild chimpanzees and orangutans select and modify thin stems to "fish" at termite mounds, or use stones to crack open nuts (Goodall, 1964;van Schaik et al, 1996van Schaik et al, , 2003Fox et al, 1999;Boesch and Boesch-Achermann, 2000). Interestingly, tool use has also been observed in wild cebus monkeys (Fernandes, 1991;Fragaszy et al, 2004;Waga et al 2006).…”

Dexterous hands, used to manipulate food, tools, and other objects, are one of the hallmarks of primate evolution. However, the neural substrate of fine manual control necessary for these behaviors remains unclear. Here, we describe the functional organization of parietal cortical areas 2 and 5 in the cebus monkey. Whereas other New World monkeys can be quite dexterous, and possess a poorly developed area 5, cebus monkeys are the only New World primate known to use a precision grip, and thus have an extended repertoire of manual behaviors. Unlike other New World Monkeys, but much like the macaque monkey, cebus monkeys possess a proprioceptive cortical area 2 and a well developed area 5, which is associated with motor planning and the generation of internal body coordinates necessary for visually guided reaching, grasping, and manipulation. The similarity of these fields in cebus monkeys and distantly related macaque monkeys with similar manual abilities indicates that the range of cortical organizations that can emerge in primates is constrained, and those that emerge are the result of highly conserved developmental mechanisms that shape the boundaries and topographic organizations of cortical areas.

“…Na floresta tropical da Costa Rica um grupo de Cebus capucinus utilizou pedaços de madeira para atacar e matar uma cobra venenosa (Bothrops asper) (Boinski, 1988). Na região de manguezal do Nordeste brasileiro, um macho adulto da espécie Cebus apella utilizou pedaços de conchas de ostras (Crassostrea rhizophorae) para bater insistentemente na concha de outra ostra até quebrá-la e se alimentar do molusco (Fernandes, 1991). Mas é nas regiões brasileiras do Cerrado e Caatinga onde há a maior concentração de uso de ferramentas por populações de macacos-prego em vida livre (Ottoni e Izar, 2008).…”
