“Because the art of Africa was on rock shelters, not deep in caves, as in Europe, the ravages of time have eroded most of a rich expression. What we now see is the merest glimpse of what was on the minds of these people.”

Origins Reconsidered: In Search of What Makes Us Human (1992)

“The neurobiologist Harry Jerison has made a long study of the trajectory of brain evolution since the advent of life on dry land. …the origin of new faunal groups is usually accompanied by a jump in the relative size of the brain, known as encephalization. …the first archaic mammals… were equipped with brains four to five times bigger than the average reptilian brain… primates are twice as encephalized as the average mammal. Within primates, the apes… are some twice the average size. And humans are three times as encephalized as the average ape.”

“The French archeologists Iégor Reznikoff and Michael Dauvois conducted detailed surveys of three decorated caves in the Ariège region of southwest France. …they moved slowly through the caves, stopping repeatedly to test the resonance of each section… spanning three octaves… those areas with highest resonance were also those most likely to harbor a painting or engraving. …a fascinating discovery that… Chris Scarre commented at the time, draws "new attention to the likely importance of music and singing in the rituals of our early ancestors."”
