In the fields of paleoanthropology and archaeology we are not just searching for bones of our early ancestors. Instead we are seeking knowledge of our biological and technological origins and how these characteristics have changed over time. Presently, the earliest fossil bipedal hominins are between 4- 7 million years old (discussed more in the next module) whereas the earliest evidence of stone tool use (based on cut marks on animal bones) is about 3.4 million years old. However, the oldest (published) stone tools uncovered are about 2.6-2.5 million years old and come from Gona, Ethiopia.
Hi I'm Linda. I'm the Resident Academic Director for the Origins Field School. In addition, I'm a geologist. I have been working in the Turkana Basin since 2011 and am interested in reconstructing the past landscape on which our ancestors evolved.
