““By running on two feet and bereft of the body hair typical of other primates, our species gained a massive advantage over larger mammals. Our ability to maintain steady pursuit gave us the capacity to hunt large prehistoric game. But persistence hunting was not only made possible because of our bodies; changes in our brains also played a significant role. During the chase, the runner is driven by the pursuit itself; and this same mental hardwiring also provides clues into the source of our insatiable desires today. The dogged determination that keeps San hunters chasing kudu is the same mechanism that keeps us wanting and buying. Although it is a long way from bushmen to businessmen, the mental processes of the hunt remain largely the same.””
