Oldest Known Bone Tools Found in Tanzania, Dating 1.5 Million Years

A recent discovery at Olduvai Gorge in Tanzania has revealed a collection of bone tools dating back 1.5 million years, which predates previous evidence of systematic bone tool production by over a million years. These tools, made from the bones of elephants and hippopotamuses, demonstrate an advanced level of cognitive ability and craftsmanship among early human ancestors, suggesting they had the capability to adapt techniques from stone to bone. The tools were systematically shaped through a process called knapping, similar to stone tool creation, indicating a significant leap in cognitive skills. Researchers believe this finding expands our understanding of early hominin technology and cognitive development, challenging previous beliefs about the timeline of tool-making. The lead author, Dr. Ignacio de la Torre, emphasized that this discovery allows for a greater appreciation of the technological options available to early humans. The analysis of 27 bone fragments has provided critical insights into the capabilities of Homo erectus during this period.
