) in Brazil’s Serra da Capivara National Park have smashed fresh cashews to peel off their caustic, unappetizing husks. The find confirms the behavior’s longtime importance to the area’s capuchins—which seem to have used the technique for a hundred generations—and adds vital nuance to the history of tool use in non-human primates …

The trove of tools, described on Monday in Current Biology, also stands to help scientists understand the bafflingly scattershot distribution of tool use among primates. Only a handful of non-human primate genera use hand tools—including chimpanzees, bearded capuchins, and long-tailed macaques—and scientists have yet to identify exactly why those species, and not others, took up tools … read more –> http://news.nationalgeographic.com/2016/07/capuchins-monkeys-stone-tools-archaeology/?utm_source=Facebook&utm_medium=Social&utm_content=link_fb20160711news-monkeyarchaeology&utm_campaign=Content&sf30714755=1
