Document Summary
The human life course and aging: life history (from birth to death, stress and adaptive responses, fetal programming, menopause as a biocultural event. Humans are unique in that they possess an array of interrelated adaptations that improve their adaptability; these include bipedality, large brains, dependence on vision, verbal communication, culture, manual dexterity, altricial-dependent infants and long lives. Life history refers to the changes through which an organism passes in its development from its primary stage of life to its natural death (fertilization,embryogenesis, fetal development, birth, infancy, juvenile, childhood, adolescence, reproductive adulthood, menopause, old age and senescence) Human life history: prenatal, neonatal, infancy, childhood, juvenile, adolescence, reproductive adulthood, old age and senescence.

(in primates, the juvenile period is the period where they sexually mature)
