ABSTRACT

By 60,000 BP humans had become a set of communities expanding their activities along coastal and inland areas of the tropics from West Africa to the South Pacific. The lifestyle of these humans likely depended on the gathering of animal and vegetable materials from water’s edge – oceans, rivers, and lakes. It appears, however, that this technology was not adequate for life in the cooler or drier climates of regions north of the tropics. Humans remained restricted to the tropics until they developed techniques for living under different ecological conditions.
