Which behavior might be seen as disadvantageous to the individual but beneficial to the group?

The behavior that is seen as disadvantageous to the individual but beneficial to the group is altruism. Altruism refers to actions that benefit others at a cost to oneself. This behavior can involve sacrificing one's own resources, time, or even safety for the benefit of others, thus promoting the well-being of the group or community.

In evolutionary terms, altruism may appear disadvantageous to the individual because it can reduce that individual's chances of survival or reproduction. However, it can enhance group cohesion, increase survival rates within the group, and ultimately contribute to the long-term success and stability of the social unit. This kind of behavior can foster cooperative relationships, increase trust, and enhance the likelihood that members of the group will support each other in times of need.

For example, in species where group living is crucial to survival, such as in many social animals, individuals may engage in altruistic behaviors that help protect the group from predators or help raise the young of others. Although these actions may not provide immediate benefits to the individual performing them, they can significantly enhance the collective strength and functionality of the group. This is why altruism is viewed as a critical component in social species and can have both immediate and long-term benefits for the society as a whole.
