"Home Bases and Early Hominids" is an article that looks at the earlier studies that suggests early hominids living in home bases and the new studies that may suggest different. The first archaeological sites from the Late Pliocene to the Lower Pliocene represented home bases suggesting that early hominids shifted their way of life to a way of life like present hunter and gathers (Potts, 338). However recent studies done from Olduvai Gorge suggests there are possible differences from early hominid to modern hunter and gathers. These differences have a significant meaning in the evolution of the hunting and gathering way of life. An archaeological site from the Paleolithic is usually defined by a concentration of stone artifacts (Potts, 338). Henri Martin and Davidson Black, tried to infer hominid behavior and ecology from the ancient archaeological remains and assumed that the association of fossil animal bones with stone tools was an important source of information about hominid activities (Potts, 338). In the nineteen sixties early archaeological sites and the study of hominid activities was much more widely acknowledged. The archaeological remains at Olduvai Gorge in Tanzania at Koobi Fora in Kenya, and in the Omo Valley of southern Ethiopia were about four times older than sites previously known. The time range of stone tool was pushed back greatly from five hundred thousand years to two million years. This brought about the very important question that every one was wondering how did these humans live? They wonder did these humans hunt and gather or live by foraging like present day baboons on the savanna. The link between early archaeological sites and hominid activities has been investigated in depth at Olduvai Gorge and Koobi For a (Potts, 338). Pott's research has focused on six stratigraphic levels at Olduvai, excavated by Leakey. Most of bones uncovered from these sites were broken some into small pieces before they were buried and fossilized.
