Deep history
Deep history is a term for the distant past of the human species. As an intellectual discipline, deep history encourages scholars in anthropology, archaeology, primatology, genetics and linguistics to work together to write a common narrative about the beginnings of humans,  and to redress what they see as an imbalance among historians, who mostly concentrate on more recent periods. Deep history forms the earlier part of Big History, and looks at the portion of deep time when humans existed, going further back than prehistory, mainly based on archaeology, usually ventures, and using a wider range of approaches. Proponents of deep history argue for a definition of history that rests not upon the invention of writing, but upon the evolution of anatomically modern humans. According to Daniel Lord Smail, perhaps the most prominent advocate of Deep History, the concept of prehistory is recast as an arbitrary boundary that limits the longue durée perspective of historians, and which rests upon assumptions that history follows a teleological path beginning with the origins of civilization in Ancient Mesopotamia.
