I think it has a connection with the Kow Swamp type (dated 15k-20k) and/or with the edge-ground axe (associated with Hoabinhian?). These are probably in turn connected with a further push into the Pacific Ocean, to the Northern Solomons. Further I believe that any early 'Caucasian' connection between Europeans, the Aborigines and the Ainu is easily explained. You may care to look at my reasoning in the essay: <br /><br />http://humanevolutionontrial.blogspot.com/2009/06/human-evolution-on-trial-into-australia.htmlterrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-8113138028665348282009-07-28T11:26:22.721+03:002009-07-28T11:26:22.721+03:00Australian Aborigines are composed of at least two...Australian Aborigines are composed of at least two major immigration events to Australia, one about 50 kya and a more recent one dating to 10 kya. Aborigines have had a long contact with their SE Asian neighbours and with the people from New Guinea.

Further, the mitochondrial DNA of Mungo Man pre-dates all known such DNA. The age of his skeletal remains is the subject of some controversy and there are estimates of 45,000 years at the lower bound and up to 60,000 years at the upper bound. Another issue concerns the finding of the cited polymorphisms and whether it is correct to assume that there is a necessary implication that they are shared by all Aboriginal people or that the only explanation would be as the result of migration from locations further west than India.<br /><br />Indeed, it would be interesting if these polymorphisms were observed in other populations along the hypothesised ex Africa route.JACK DANIELShttps://www.blogger.com/profile/10868442960238232424noreply@blogger.com
