“We live like zoo animals!” It’s an idea Erwan Le Corre borrowed from the British zoologist Desmond Morris, author of the 1967 classic “The Naked Ape,” and it’s central to his worldview: that we are essentially wild creatures ill-suited to desk jobs and processed foods. “We have become divorced from nature, trapped in colorless boxes,” Le Corre says. “We have lost our adaptability, and it’s threatening our health and longevity.”
