Hunting and Gathering

By 12,000 years ago at the latest, human populations had spread into most of the habitable regions of the globe, including Australia and North and South America. With the aid of their flexible, rapidly evolving cultures, these groups, loosely organized as small bands of "hunter-gatherers," were able to adapt to virtually all the climate zones and environmental niches on the planet, from the Arctic  to temperate zones  to the tropics. This was fair how things canged today because we made that hapen to day.
