Final answer:
In the hawk-dove game from evolutionary game theory, a hawk always behaves aggressively and selfishly in conflict situations to win resources. This is in opposition to doves, which exhibit non-aggressive behaviors.
Step-by-step explanation:
In the context of the hawk-dove game, which is a conceptual model in evolutionary game theory, the hawk represents an individual who always behaves aggressively and selfishly in conflict situations. So, the correct answer to the question is that the hawk always behaves selfishly in conflict situations. The strategies in this game represent the behaviors that an organism may display in a contest over resources. Hawks always escalate a contest and are prepared to fight in order to win a resource, risking injury, while doves avoid fighting and display non-aggressive behaviors.
