Quizplus · Accepted Answer

The black-tailed prairie dogs making alarm calls to warn others of a predator is an example of altruism, as it is a behavior that benefits others at a potential cost to the individual making the call. The individual making the call increases the risk of predation to themselves by drawing attention to their location, but the benefit to the group as a whole (increased chances of survival) outweighs this cost. This behavior is not an example of mutual benefit, as the individual making the call does not directly receive any benefit from others responding to the warning. It is also not an example of selfishness or spite, as there is no direct harm or benefit to the other individuals in the group.
