Over in southern Africa 100,000 years ago, Homo sapiens was pretty new on the scene. A favorite hangout was a cave named Blombos near the Southern ocean.
Archaeologists like Christopher Henshilwood have spent decades finding stuff there that our ancestors left behind. Recently, Henshilwood uncovered two abalone shells with ocher ground into the shell.
