The Wonderwerk Cave site in South Africa is one of very few places on Earth where human activity can be traced back continuously across millennia, and scientists just established the oldest evidence of archaic human habitation in the cave: some 1.8 million years ago. That s based on an analysis of sedimentary layers containing animal bones, the remnants of burning fires, and Oldowan stone tools: Objects made from simple rocks with flakes chipped off to sharpen them, representing what was once a significant step forward in tool technology. While tool artifacts at other sites have been backdated as far as 3.3 million years ago, the new findings are now thought to be the earliest sign of continuous prehistoric human living inside a cave - with the use of fire and tools in one fixed location indoors.
