Cooperation and Sociality
Societies comprise aggregations of individuals interacting cooperatively with one another, but it is not immediately clear why such systems are not undermined by free-riders that accept cooperative acts while giving little or nothing in return. There are several ways in which cooperation can emerge and remain stable within societies despite self-interest. Kin selection may help explain much intraspecific cooperation, but it is not the only mechanism, and sometimes cooperation can be maintained by a complex interplay of several types of interaction, including reciprocity, partner choice, and the threat of punishment.
