This is a totally new way of looking at the evolution of the human brain. It is so totally fresh, unexpected and hitherto un-thought-of that it will probably take a long time before evolutionary anthropologists and psychologists begin to take it on board; but it will make an impact, of that there is no doubt. It will be, it must be, taken very seriously in any discussion of human origins. Colin Groves: (Professor of Biological Anthropology at the School of Archaeology & Anthropology, Australian National University and author of several books including A Theory Of Human And Primate Evolution and Bones, Stones and Molecules)
