Knives are among the oldest pieces of human technology. Metal knives have been part of the human toolkit for thousands of years, but it’s mind-boggling to consider how long our ancestors used stone cutting tools like this one. This javelin tip, discovered in Ethiopia, is believed to be 280,000 years old.
This is believed to be the earliest date for the use of stone-tipped thrown javelins, predating earlier similar discoveries by almost 200,000 years. What’s more amazing is that these stone-tipped javelins were made by prehuman hominids, because anatomically modern homo sapiens sapiens only appeared 200,000 years ago.
