#499 Humans Aren’t Supposed to Live This Long (Grandmothers Might Explain Why) - Dr Kristen Hawkes

Professor Kristen Hawkes is a pioneering anthropologist whose work helped bring the grandmother hypothesis to the spotlight of human evolution research. Through fieldwork and evolutionary theory, she argued that older women may have played a crucial role in shaping the human life course, not just by living longer, but by helping feed and support grandchildren. That idea helped reframe menopause, longevity, and family cooperation as possible drivers of what makes humans distinct and what explains our longer lifespans.
