Earliest communities

For all except approximately the last 10,000 years, man has lived almost entirely in small nomadic communities, dependent for survival on his skill in gathering food by hunting and fishing and in avoiding predators. It is reasonable to suppose that most of these communities developed in tropical latitudes, especially in Africa, where climatic conditions are most favorable to a creature with such poor bodily protection as man. It is also reasonable to suppose that tribes of men moved out thence into the subtropical regions and eventually into the landmass of Eurasia, although their colonization of this region must have been severely limited by the successive periods of glaciations, which rendered large parts of it inhospitable and even uninhabitable, even though man has shown remarkable versatility in adapting to such unfavorable conditions
