Savanna Chimpanzees, Pan troglodytes verus, Hunt with Tools by Jill D. Pruetz and Paco Bertolani
Tool construction entailed up to five steps, including trimming the tool tip to a point. Tools were used in the manner of a spear, rather than a probe or rousing tool. This new information on chimpanzee tool use has important implications for the evolution of tool use and construction for hunting in the earliest hominids, especially given our observations that females and immature chimpanzees exhibited this behavior more frequently than adult males.
The full paper, from 2007, was available as a pdf when I visited (I don’t really trust these publishers and what articles by professors they will block access to later when they don’t clearly say it is open access – in fact the journal broke the link on the post I made about this in 2007 now that I checked – sigh).
The full paper isn’t filled with overly complex scientific jargon (as scientific papers can be). In that sense it is an easy read; it is a bit graphic for those that are squeamish.
Dr. Jill Pruetz maintains an interesting blog the Chimpanzees she studies: Fongoli Savanna Chimpanzee Project
