Asia
The coastal periphery was home to some of the world's earliest known civilizations, each of them developing around fertile river valleys. The civilizations in Mesopotamia, the Indus Valley and the Yellow River shared many similarities. These civilizations may well have exchanged technologies and ideas such as mathematics and the wheel. Other innovations, such as writing, seem to have been developed individually in each area. Cities, states and empires developed in these lowlands.
Prehistoric Europe
Prehistoric Europe is the designation for the period of human presence in Europe before the start of recorded history, beginning in the Lower Paleolithic. As history progresses, considerable regional irregularities of cultural development emerge and increase. The region of the eastern Mediterranean is, due to its geographic proximity, greatly influenced and inspired by the classical Middle Eastern civilizations, and adopts and develops the earliest systems of communal organisation and writing. The Histories of Herodotus (from around 440 BC) is the oldest known European text that seeks to systematically record traditions, public affairs and notable events. In contrast, the European regions furthest away from the ancient centers of civilisation tended to be the slowest, regarding acculturation. In Northern and Eastern Europe in particular, writing and systematic recording was only introduced in the context of Christianization, after 1000 CE.
Widely dispersed, isolated finds of individual fossils of bone fragments (Atapuerca, Mauer mandible), stone artifacts or assemblages that suggest Lower Paleolithic palaeo-human presence are rare and typically separated by thousands of years. The karstic region of the Atapuerca Mountains in Spain represents the currently earliest known and reliably dated location of residence for more than a single generation and a group of individuals. Prolonged presence has been attested for "Homo antecessor" (or "Homo erectus antecessor", "Homo heidelbergensis" and Neanderthals.
