In "A Hunter-Gatherer's Guide to the 21st Century," evolutionary biologists reveal why our ancient biology clashes with modern life. Praised for challenging prevailing narratives, they offer a provocative question: What if our evolutionary mismatch explains today's sleep deprivation, dangerous diets, and social disconnection?

A stranger's cryptic warning-"rain in the mountains"-saved two biologists from drowning in a Costa Rican river in 1994. They watched in stunned silence as the water transformed from calm to violent in moments, carrying trees and debris downstream. That local man possessed something most modern humans have lost: ancestral wisdom about how the world actually works. We've traded survival knowledge for technological comfort, and the cost is higher than we realize. Our bodies evolved over millions of years to thrive in specific conditions, yet we now live in environments that would baffle our ancestors. We're running ancient software on hardware designed for a world that no longer exists, and the system is crashing. This disconnect-what we might call evolutionary mismatch-explains much of modern misery. We sit for hours despite bodies built for constant movement. We eat foods our great-grandparents wouldn't recognize. We sleep under artificial lights that confuse our circadian rhythms. We raise children in ways that would seem bizarre to 99% of humans who ever lived. The result? Epidemics of anxiety, depression, obesity, and chronic disease that were virtually unknown to our hunter-gatherer ancestors. We're not broken-we're just wildly out of context.
