A social interaction between an actor and a recipient can influence their relative fitness. When the outcome of such an interaction brings harm to both participants, the action is described as being _________.
A. asymbiotic.
B. spiteful.
C. antagonistic.
D. selfish.
i. Actors and recipients are characterised by increased reproductive success in mutually beneficial interactions.
ii. Actors benefit and recipients incur costs (i.e., are harmed) in selfish interactions.
iii. Actors incur costs (i.e., are harmed) and recipients benefit in altruistic interactions.
iv. Actors incur costs (i.e., are harmed) and recipients incur greater costs in spiteful interactions.v. Hamilton's rule can be used to show that an allele encoding altruistic behaviour could be favoured; spiteful behavior, however, never can evolve.
