Bones that appear to have been fashioned into tools date back 1.5 million years CSIC
Ancient humans were regularly making tools out of animal bones 1.5 million years ago – more than a million years earlier than previously thought. This indicates that they could adapt the techniques they used to make stone tools to repurpose bone, a very different material.
It also raises the question of why there is no record of people consistently making bone tools for another million years. Have examples in that gap not been preserved or discovered, or did people abandon them in favour of something better?…
