Spectrums of Ostrich Eggs

These are pieces of fossilized ostrich egg, found in an archaeological dig in South Africa. They are dated to between 60 and 70 thousand years old, and they represent some of the oldest human art ever discovered. Nothing too complicated - just lines and dots and stains. But that's all it takes, really, to show us that our long gone brothers and sisters were thinking abstractly, in symbols, for a long, long time. Another feature which separates mankind from our animal cousins.
