    Study Notes

    Social Groups and Social Behavior

    • Social groups are formed by animals, including humans, to increase survival and reproductive success.
    • These groups have certain characteristics, such as similar interests, geographic location, and shared activities.
    • Examples of social groups in animals include apes living and hunting together, and goats with specific accents depending on their social group.

    Costs and Benefits of Living in Groups

    • There are two main benefits of living in groups: improved hunting success and improved protection from predators.
    • Examples of improved hunting success include dolphins trapping more fish when hunting together, and lions teaming up to hunt large prey.
    • Examples of improved protection from predators include the difficulty of a sole predator to isolate one individual from a large group, and the protection of a school of fish from a dolphin.

    Costs of Living in Groups

    • There are two main costs of living in groups: an increase in competition and an increase in the spread of diseases.
    • Examples of increased competition include more mouths to feed, leading to competition for food, and competition for mates.
    • Examples of increased spread of diseases include the easy transmission of illnesses from one individual to another in a close-knit group.

    Altruism and Kin Selection

    • Altruism is a behavior that benefits the recipient at a cost to the performer.
    • Examples of altruism include a lifeguard or firefighter putting the well-being of others before their own.
    • Kin selection is the concept of an individual choosing to help its relatives to increase the survival of its traits.
    • Examples of kin selection include humans being more likely to donate a kidney to a relative than to a stranger.

    Considerations for Altruism

    • Individuals must consider three main items when it comes to altruism: energy cost, opportunity cost, and risk cost.
    • Energy cost concerns the amount of energy required to perform an altruistic act.
    • Opportunity cost concerns the other actions an individual may miss out on by performing an altruistic act.
    • Risk cost concerns the increased chance of being injured or killed as a result of performing an altruistic act.
