The Bright Side: Researchers glimpse early signs of human technology with oldest wooden tools

The world's oldest wooden tools – likely dating back 430,000 years and possibly used by Neanderthals or early human ancestors – have been uncovered in Greece's Megalopolis basin. Researchers say the spindly stick used for digging and a handheld chunk of wood, possibly used to shape stones, give a rare glimpse of early human technology.
