Life History Theory is about human biology and how natural selection works throughout the lifecycle of humans. Life history theory is the study of how the human body’s organisms use strategy to allocate its limited energy toward growth, maintenance, reproduction, raising offspring and avoiding death. There is limited amount of energy in the human body that’s available to the organisms for growth, maintenance and reproduction and when the energy is being used for one of these tasks there is not enough energy for the others. Life history for humans considers the whole picture in terms of how energy is allocated for the process of growth development and maturation of an organism from conception to death. According to the life history approach our entire lifecycle represents a series of trade-offs between allocating energy towards different life history traits using this idea of limited energy and trade-offs. Life history theory tries to answer the questions about the unique aspects of human development and lifecycle compared to other primates. Their life stages and their durations are compared to other species to identify where we are different and tries to explain why. Life history theory explains how natural selection and evolution work together for organisms to survive and reproduce in our ever changing environment. Life history theory looks at human lifespan stages through birth, infancy, childhood, reaching puberty, through reproduction stage, menopause, grandma stage  and death. We may have a better understanding of why we get old and die as life history approach answers the questions as to why we have evolved the way we did and why we have the particulars of the lifecycle that we have and it helps us understand how decisions that are made biologically and behaviorally early in life, particularly during prenatal and postnatal growth and development, affect
