Cognito wrote:HSS population studies are more developed, but this entire area is fascinating with no easy answer to: Why did the HSS population rapidly expand after 50,000bce while HN remained static? So far, there is no clearcut answer.
The clearcut, one word answer:
BOATS - and all the food that goes with them
Maybe so, but
H. erectus also made it to Flores about 800kya plus. Maybe the difference is: they used simple rafts while 50kya boats with sails were first used. It certainly explains rapid dissemination throughout the world, initially along the coasts.
I recently read an interesting comment regarding the establishment of Australia and subsequent explosion of voyaging into the east Pacific at 50kya. Where is the evidence? Tsunamis apparently took care of most traces - living on a low altitude island is eventually hazardous to your health or those of your progeny.
By the way, EP, I finished going through your book for the third time. Due to the abundance of material and references presented it took that many times to absorb its impact. I appreciate the inclusion of so many oral traditions - a must read for anyone who is interested in Paleo America.
Thanks, Cognito, please be sure to tell your friends - I can really use the sales right now. Since putting the book together gave me a stroke, right now I'm feeling like the book will do quite well right after it's finished killing me.
Despite that, I feel that it will ultimately attain the same stature as Gibbon's Decline and Fall of the Roman Empire, Tuchmann's Guns of August, and some of Linda Schele's volumes. Anyone who buys a signed first edition copy is making a great investment, posthumously, but please don't pray for an immediate increase in the value of your investment.
I also take a certain pleasure in knowing that wherever you travel, the peoples will live for you again when you are at their sites. Enjoy, and Paselo.
While the Flores materials are under question, I read in Current Archaeology about new and even earlier finds from Taiwan that are firm.
Unfortunately, with this damn stroke I can not repeat them back to you, but that's where to look.
The HSS materials in Australia are firm, and there's only one way HSS could have got there. I can't give you URLs, but you can find them through google. I also posted a bit about the new book on this, but with this damn stroke, it's going to be tough to find that again.
Right about the tsunami - not only do we have the tectonic induced tsunami, but we have those perky impact tsunami as well. The next impact mega-tsunami is likely to kill at least 60 million people or so, unless mankind gets on this problem right fast.
The raft probably came after simple river rafts developed in Asia, but the tech could have appeared anywhere from the East Coast of Africa, through India, to Asia. My guess is Asia, but that's simply a guess; in any case, the spread from that point must have been rapid. The key here is going to be finding well dated marine hunting tools, and the remains of marine meals - I think that sea turtles were key to some degree.
While tools for rafts may not have been specialized, the dugout tools probably were, so that's something else that's going to have to be watched out for.
