The recent discovery of bone artifacts in Tanzania has pushed back the earliest known date of bone tool technology by over a million years. Archaeologists in Olduvai Gorge unearthed a collection of bone tools believed to have been crafted by an ancestral human species known as Homo habilis 1.5 million years ago.
These bone artifacts, attributed to the Oldowan people, complement their existing reputation for stone tool use dating back 2.5 million years. The new findings reveal a more sophisticated and advanced tool technology previously unknown.
Archaeologist Ignacio de la Torre of the Spanish National Research Council highlights the significance of this discovery, suggesting an expansion in early humans’ technological capabilities and cognitive capacities attributed to the incorporation of bone materials in tool production.
This advancement in tool technology, evident through the deliberate alteration of bones for tool-making purposes, offers insight into the transition between the Oldowan and Acheulean cultures. The tools, predominantly made from elephant and hippopotamus bones, potentially served various functions such as butchering.
Undoubtedly, these findings shed light on the complexity and innovation of our human ancestors, paving the way for further exploration and understanding of their technological and cognitive evolution.
Published in Nature, this research marks a significant milestone in our understanding of ancient toolmaking practices.
