“During most all of human evolution, it was adaptive to conserve energy by being lazy as circumstances permitted. Energy was a vitally needed resourse and could not be wasted. Today this take-it-easy adaptation may lead us to watch tennis on television when we would be better off playing it. This can only aggravate the effects of excess nutrition. The average office worker would be much more healthy if he or she spent the day digging clams or harvesting fruit in scattered tall trees.”

“Except for professional athletes, dancers, cowboys, and a few other groups, most people in modern industrial societies have abnormally low energy expenditures. Workers sitting in swivel chairs or in driver's seats of cars or even pushing vacuum cleaners or electrically powered lawn mowers are being sedentary, and their leisure hours may be even more so.”

“Our dietary problems arise from a mismatch between the tastes evolved for Stone Age conditions and their likely effects today. Fat, sugar, and salt were in short supply through nearly all of our evolutionary history. Almost everyone, most of the time, would have been better off with more of these substances, and it was consistenly adaptive to want more and try to get it. Today most of us can afford to eat more fat, sugar, and salt than is biologically adaptive, more than would ever have been available to our ancestors of a few thousands years ago.”

“Just as the capacity for experiencing fatigue has evolved to protect us from overexertion, the capacity for sadness may have evolved to prevent additional losses. Maladaptive extremes of anxiety, sadness, and other emotions make more sense when we understand their evolutionary origins and normal, adaptive functions.”

“Emotional capacities are shaped by situations that occurred repeatedly in the course of evolution and that were important to fitness. Attacks by predators, threats of exclusion from the group, and opportunities for mating were frequent and important enough to have shaped special patterns of preparedness, such as panic, social fear, and sexual arousal. Situations that are best avoided shape aversive emotions, while situations that involve opportunity shape positive emotions.”
