not cooperate. Besides Hawk-Dove, other well-studied games of this type are the game of chicken and the snowdrift game (Doebeli and liauert. 2005: Nowak, 2006a). We introduce a two-player survival game which can fall into any of these four classes. It may also change, for example from a Hawk-Dove g

in which having a different behavior than one's partner produces a higher payoff. Doves cooperate by sharing resources but retreat when challenged. Hawks do not cooperate. They are ready to fight to avoid leaving an interaction empty-handed. A Hawk gets the entire resource when facing a Dove but suff
