In traditional historical estimations, the first human civilizations appeared in two particular places, with one important center in the Tigris-Euphrates river-valley in the Middle East and another along the Yellow River in modern-day China. More recent estimations add civilizational centers in Africa as either contemporaneous with or perhaps even predating the civilizations identified in the traditional views.
