Diamond explains how geography shaped human migration, not simply by making travel difficult, but by how climates affect where domestic able animals can easily travel and where crops can ideally grow easily due to the sun. Seasonally variable climate at high latitude poses more diverse challenges than does a seasonally constant tropical climate. Cold climates require one to be more technologically inventive to survive, because one must build a warm home and make warm clothing. Whereas one can survive in the tropics with simpler housing and no clothing. The first step towards civilization is the move from hunter-gatherer to agriculture with the domestication and farming of wild crops and animals. Agricultural production leads to food surpluses and this in turn supports sedentary societies, rapid population growth, and specialization of labor. Large societies tend to develop ruling classes and supporting bureaucracies, which leads in turn to the organization of empires. Although agriculture arose in several parts of the
