Michael Gurven’s “Seven Decades: How We Evolved to Live Longer” explores the origins of human longevity, challenging the common belief that life in the past was short and harsh. Gurven draws on anthropological fieldwork—especially among Indigenous societies—to argue that the capacity for long, healthy lives is deeply rooted in our species’ evolutionary trajectory and not just a recent outcome of modern health and technology. The book blends storytelling with scientific analysis to reevaluate what it means to age and advocates for societal changes inspired by ancestral wisdom.
