A. Christakis introduces the compelling idea that our genes affect not only our bodies and behaviors, but also the ways in which we make societies, ones that are surprisingly similar worldwide. With many vivid examples -- including diverse historical and contemporary cultures, communities formed in the wake of shipwrecks, commune dwellers seeking utopia, online groups thrown together by design or involving artificially intelligent bots and even the tender and complex social arrangements of elephants and dolphins that so resemble our own - Christakis shows that, despite a human history replete with violence, we cannot escape our social blueprint for goodness. In a world of increasing political and economic polarisation, it's tempting to ignore the positive role of our evolutionary past. But by exploring the ancient roots of goodness in civilisation, Blueprint shows that our genes have shaped societies for our welfare and that, in a feedback loop stretching back many thousands of years, societies have shaped and are still shaping, our genes today.
