The forager's dilemma: food sharing and food defense as risk-sensitive foraging options.
2003
Although many variants of the hawk-dove game predict the frequency at which group foraging animals should compete aggressively, none of them can explain why a large number of group foraging animals share food clumps without any overt aggression. One reason for this shortcoming is that hawk-dove games typically consider only a single contest, while most group foraging situations involve opponents that interact repeatedly over discovered food clumps. The present iterated hawk-dove game predicts that in situations that are analogous to a prisoner's dilemma, animals should share the resources without aggression, provided that the number of simultaneously available food clumps is sufficiently la…
Indication for social interaction during the Central European Late Upper Palaeolithic: Evidence from the Magdalenian site of Oelknitz, Structure 1 (T…

Abstract The current paper reports on the faunal assemblage from Structure 1 at the German Magdalenian site of Oelknitz. The composition of the fauna is characterised by a dominance of horse. The horses were exploited for meat and marrow. A strict spatial separation of carcass parts is obvious, also observed at other Magdalenian sites, where the evidence was interpreted in terms of social interaction and food sharing. This is discussed against the contextual background of the site of Oelknitz. It is suggested that the way in which Magdalenians interacted socially is independent of site function.
