ABSTRACT
As with all play-assemblies, the present study shows that the ‘tug-of-war’ has a developmental trajectory all of its own, entwined with those of the other ensembles. Although I have not the space here to tell you about this development, it again involves interpersonal companionship between the young, apprentice chimpanzee and his or her older and more experienced friends and relations, who provide and support learning opportunities for the learner. Perhaps now, in a fi ght with himself with this black stick, Kimoni represents the tug-of-war of moments ago, with his mother, over a white stick.
