"One day, perhaps five million years later, a cold wind blew through this Eden. The seas receded, the ice caps expanded. A spit of land emerged from the tides, a bridge that a few adventurous apes followed out of Africa. Nomads, wanderers, they settled in the rain forests that blanketed Eurasia. But the cooling continued, replacing tropical groves of fruit with deciduous forests, where the leaves flame in autumn, then die. A time of famine followed. The woods filled with starving apes. “At some point a mutation occurred in one of those apes,” Johnson explained. It made that ape a wildly efficient processor of fructose. Even small amounts were stored as fat, a huge survival advantage in months when winter lay upon the land and food was scarce."
