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.

- There are a wide range of potential costs and benefits of living in a group. Sometimes these costs and benefits can create tradeoffs with respect to optimal group size. The following graphs show two such factors – risk of disease (in red) and risk of predation (in black). Researchers can use these relationships to predict optimal group size (yellow star). Which of the following graphs is most consistent with what you would expect for these costs and benefits of group living?arrow_forwardImportant benefits of living in a society include a. increasing susceptibility to predation. b. increased awareness of danger. c. increasing individuals’ visibility. d. increasing competition for food and mates.arrow_forwardShould the environment be treated as a person?
