#Unit 11. Evolution and Behavior

When the fitness interests of two individuals are different, they are in conflict.

The evolution of cooperation and conflict depends on when these kinds of behaviors are favored by natural selection.

When one individual provides a fitness benefit to another, as long as the second individual is likely to return the favor later.
