The Development of Human Reproductive Strategies: Progress and Prospects

An evolutionary-biological perspective on the effects of the extrafamilial and familial environment on multiple psychological, behavioral, and even somatic features of children's development challenges prevailing thinking about human development, which regards some contextual conditions and their sequelae as "good" and others as "bad." Theory and research on the development of human reproductive strategies based on such evolutionary thinking has evolved substantially over the past two decades. In this article, I review two decades of theory and research findings pertaining to the development of reproductive strategies-highlighting the contextual regulation of pubertal timing, the distinctive role of fathers, individuals' differential susceptibility to rearing influences, mechanisms of influence, and new ways of conceptualizing influential environmental features-and outline future directions for research.
