The book explores the intersection of evolutionary biology and existential risk, examining how humanity's evolutionary past influences contemporary challenges and threats to our survival. It delves into the cognitive and social traits inherited from our ancestors that shape human behavior and decision-making, potentially exacerbating global issues such as climate change, technological risks, and geopolitical conflicts. Through an interdisciplinary approach, the author argues for a deeper understanding of these evolutionary influences to better address and mitigate the existential risks facing humanity today.
