"On the Origin of Being" pays homage to Charles Darwin by offering an evolutionary answer to the question, “How do we live a good life?” When humans live in accord with their evolutionary design, we experience health and well-being, however, most modern humans live in discord. By tracing the evolutionary origins of many behaviors from single-celled organisms to hunter-gatherers, the authors not only reveal how modernity disrupts them but also how to realign with our primal selves. Book 1 covers sleep, nutrition, work and rest, and our connection with nature.
