Reproductive Ecology and Evolutionary Anthropology: Foundations, Unanswered Questions, and Future Directions

The research field of reproductive ecology continues to be a major contributor to the scientific advancement of evolutionary anthropology and human biology in general. Primary contributions to human evolutionary biology include a greater understanding of the physiological mechanisms that manage lifetime reproductive effort, resource allocation, life history trade-offs, demographic variation in fertility, the adaptive traits that define humans (Homo sapiens), non-human primates, and our hominid ancestors as well as novel insights into reproductive health challenges such as cancer. Here we present a brief overview of the foundation on which this research path is based, including a summary of current research advances in human reproductive ecology, particularly within the scope of human variation. Future research directions, unanswered questions, and engagement with reproductive health challenges are discussed.
