The purpose of this research was to examine aimed throwing of stones by tufted capuchin monkeys (Cebus apella). Three capuchins (two adults and one juvenile) threw stones at a stationary target located outside their home cages. The monkeys subsequently discriminated between stationary targets and threw stones at a moving target. Each subject exhibited a distinct manual and postural throwing preference. These results demonstrate that capuchins have throwing capabilities which are thought to have been associated with early hominid evolution.
