    The answer to the question of when and where early man first started to produce art has profound significance for paleontologist. 39 The discovery of Paleolithic art in the form of cave painting in the caves of Lascauz and Chauvet in the Pyrenees Mountains of France transformed our judgments about primitive human culture. These discoveries led to the long- dominant hypothesis that while humans most likely originated in Africa and learned to make tools there, it was not until 35,000 years ago-the time of the French cave painting-that other forms of modern behavior including advanced language and
symbolic expression began to appear.
       40    While excavating a cave near the southernmost part of Sough Africa, paleontologists discovered two pieces of ochre rock adorned with geometric patterns.    41    That makes them twice as old as the oldest age given for the cave paintings in France.
       42     But most significantly, the early artist decorated the stones with a complex geometric array of carved lines. These non-representational markings suggest that early Homo sapiens were able to think abstract thoughts.    43    The choice of material alone is sufficient to indicate a certain level of sophistication, since the ochre would have come from at least 20 miles away and would have had to be mined and transported.
