human life history

Human life history describes the sequence and timing of key biological and behavioral stages in a person's life, such as growth, reproduction, and aging. It involves how we develop from infancy, reach adulthood, reproduce, and eventually decline. These stages are influenced by genetics, environment, and cultural factors, shaping how long we live, when we have children, and how we allocate energy between growth, reproduction, and maintenance of health. Understanding human life history helps explain patterns of development, lifespan, and reproductive strategies across different populations and environments.
