Caves riddle the cliffs upon which Pinnacle Point in ZA was built. Stone Age people lived in these caves around 150,000 years ago. The caves are believed to show evidence of symbolic behavior occurring far earlier than was commonly thought, going back to at least 75,000 years ago and including beads, heat-hardened tools -- so, in other words, this is where the command of fire was born -- abstract art, and systemic exploitation of shellfish. (Some speculate the nutrients in shellfish enabled these people to develop mental capacity.)
In other words, experts believe this area may be where civilization was born -- one controversial contention is the Ice Age wiped out humans everywhere but a swath of the African coast including Pinnacle Point, and that we all descend from that hardy band.
So: prehistoric -- but "historic".
