      This review provides an evolutionary perspective on close social relationships. We focus on three core issues: their function, their number and quality, and their maintenance. Our aim is not to provide a unified theory of relationships, but rather to synthesize evidence from social psychology, evolutionary theory, ethology, anthropology, and sociology in an attempt to develop a more integrated approach. For these purposes, we focus on three different types of social bonds: mateships, kinship bonds, and friendships.
