The oldest drawing ?

Scientists say they have discovered humanity's oldest known drawing on a small fragment of rock in South Africa. The drawing is about 73,000 years old, and shows cross-hatch lines sketched onto stone with red ochre pigment. Scientists discovered the small fragment of the drawing - which some say looks a bit like a hashtag - in Blombos Cave on the southern coast.

The find is "a prime indicator of modern cognition" in our species, the report says.While scientists have found older engravings around the world, research published on Wednesday in the journal Nature says the lines on this stone mark the first abstract drawing.

The drawing was "probably more complex" in its entirety, archaeologist Christopher Henshilwood told Reuters. "The abrupt termination of all lines on the fragment edges indicates that the pattern originally extended over a larger surface," he said.
