24 – Earliest known hafted hunting technology

500,000 years ago

Stone tool technology has undergone massive changes from the original simple flaked tools. Perhaps the most versatile of these advancements is the invention of hafted tools. The earliest evidence for hafted tools, where a stone tool is attached to a wooden or bone handle to create a compound tool, precede the date for Homo sapiens. Stone points found at Kathu Pan, South Africa, were likely used as spear tips and hafted to wooden staves.
