Why is africa considered the “cradle of art and civilization”?

Answers may vary, but should be similar to the following: The earlier discovery of Paleolithic art revolutionized ideas of what primitive human cultures might have been capable of. The creation of art is considered to indicate an advance in both the linguistic and cultural development of a population. The discovery of the cave paintings in the 1940s in France led to an hypothesis that while humans most likely originated in Africa, and learned to make tools there, it was not until the time of the French cave paintings, 35,000 ago at most, that forms of modern behavior including advanced language and symbolic expression, such as art began to appear.
