THE GUARDIAN/A 65,000-year-old tool – a kind of ancient Swiss Army knife – found across southern Africa has provided scientists with proof that the ancestors of modern homo sapiens were communicating with each other.
In a world first, a team of international scientists have found early humans across the continent made the stone tool in exactly the same shape, using the same template, showing that they shared knowledge with each other.
The artefacts, also known as the “stone Swiss Army knife” of prehistory, were made to a similar template across great distances, the study reveals.
