The very concept of the ‘birth’ or ‘origin’ of art may seem inappropriate, since humans are by nature artists and the history of art begins with that of humanity.

Evidence from a huge analysis of rock art (...) and cave paintings and engravings shows that, from their origins, humans have also been Homo aestheticus. (shrink)
