Ancient Humans Used Animal Bones as Cutting Tools 1.5 Million Years Ago
Recent discoveries in Tanzania’s Olduvai Canyon showed that early humans were making skeletal tools from 1.5 million years ago, reducing previous estimates by a million years. Researchers have discovered 27 well-preserved bone tools, probably made from bones on leg of elephants and hippos, which appear to have been molded into hand axes to slaughter slaughtered bodies. This study published in nature shows that early human genus had a more complex toolkit than previously thought. While it is not clear which human ancestral species have made these tools, possible candidates include Homo homo habilis and paranthropus boisei. The findings challenge previous ideas about early tool manufacturing and highlight the ever-evolving creativity of ancient humans.
