Well, I did say we were making the best use of the Singapore National Library!! Archaeology first came to my attention when our family visited Skara Brae, a 5,000 year old neolithic stone-built village in the Orkney Isles, when I was but a young boy This book connects the human timeline across our the planet, making it clear that peoples everywhere were doing it for themselves but in very similar ways. Recently 'cave art' in Indonesia has been dated to around 40,000.
"It was previously thought that Western Europe (Spain) was the centerpiece of a 'symbolic explosion' in early human artistic activity, such as cave painting and other forms of image making, including figurative art, around 40,000 years ago," said study leader Maxime Aubert, an archaeologist and geochemist at Australia's Griffith University. "However, our findings show that cave art was made at opposite ends of the Pleistocene Eurasian world at about the same time, suggesting these practices have deeper origins — perhaps in Africa before our species left this continent and spread across the globe."
Or was it a parallel development in human tribes that could not possible have been in contact with one another, as shown by later parallel developments out lined in Justin's book? Hummmm.
