Tooj 17 Posted February 23, 2007 Share Posted February 23, 2007 http://news.bbc.co.uk/2/hi/science/nature/6387611.stm Chimpanzees in Senegal have been observed making and using wooden spears to hunt other primates, according to a study in the journal Current Biology. Researchers documented 22 cases of chimps fashioning tools to jab at smaller primates sheltering in cavities of hollow branches or tree trunks. The report's authors, Jill Pruetz and Paco Bertolani, said the finding could have implications for human evolution. Chimps had not been previously observed hunting other animals with tools. Pruetz and Bertolani made the discovery at their research site in Fongoli, Senegal, between March 2005 and July 2006. "There were hints that this behavior might occur, but it was one time at a different site," said Jill Pruetz, assistant professor of anthropology at Iowa State University, US. "While in Senegal for the spring semester, I saw about 13 different hunting bouts. So it really is habitual." Jabbing weapon Chimpanzees were observed jabbing the spears into hollow trunks or branches, over and over again. After the chimp removed the tool, it would frequently smell or lick it. In the vast majority of cases, the chimps used the tools in the manner of a spear, not as probes. The researchers say they were using enough force to injure an animal that may have been hiding inside. In one case, Pruetz and Bertolani witnessed a chimpanzee extract a bushbaby with a spear. In most cases, the Fongoli chimpanzees carried out four or more steps to manufacture spears for hunting. In all but one of the cases, chimps broke off a living branch to make their tool. They would then trim the side branches and leaves. In a number of cases, chimps also trimmed the ends of the branch and stripped it of bark. Some chimps also sharpened the tip of the tool with their teeth. Adult males have long been regarded as the hunters in chimp groups. But the authors of the paper in Current Biology said females and juveniles were seen exhibiting this behaviour more frequently than adult males.

Gejon 2 Posted February 23, 2007 Share Posted February 23, 2007 I like the way they were "caught" aswell, can just imagine the sneaky chimps running around with the spears then standing there with there hands behind their backs and their heads down in shame when they were "caught" Link to comment Share on other sites More sharing options...
