And isn't it a little convenient to just say they were killed off by the Asian tribes???
University of Sao Paolo, Brazil, first Americans, where??? Brazil or adjacent to Argentina...Prime location of civilization of the American cultures. It is called bragging rights. For countries like Brazil, if you can't be first bend the rules to fit your Carnival.
Spirit Cave Man Is the oldest mummy ever found in the Americas. He died in his mid-40's, 9,400 years ago in Nevada. Still had all his clothes and his shoes on when found.
Some believe he is from the same human group as Kennewick Man, Buhl Woman and many un-named others.
"It just that the Aboriginees sailing to Brazil 12,000 years ago and wind up as a not so technological society, is a stretch. If the Olmecs, Aztecs, Incas, Mayans, Anasazi, etc. etc. are decendents of Aboriginal Australians, would it not make sense that Aboriginals be a little more sophisticated than their history suggest??? "
where on earth is anyone claiming the INDIAN civilizations you name are anything but Indian aka mongoloid?
Not that what you pointed would be the real problem, though. The expectation that Australian aboriginals should be more technologically advanced if Amerindian civilizations descends from them assumes that technology/culture isn't something passed on by its own non-genetic means, but rather that it's intrinsic of a population and would promptly pop up out of their foreheads.
As if would be reasonable to expect that if we take a bunch of people from some country and drop them in some island in the middle of nowhere with their body clothes, a few years after we would find that they just reinvented a miniature version of their original country, with all the technology and culture that they had; as if all the inventions and achievements of a population were somehow inherently known by any individual pertaining to that population.
The genetical/mutational basis of the so called “inventions”, perhaps. Maybe with some retroviral transmission to explain the odd fact that not only descendants of an individual inventor can actually build the invention, that other people apparently “learn” to build and how it works. What is thought to be “teaching” perhaps is just some social gathering that really serve only to promote viral transmission of “culture”, not the so called “cultural” transmission.
The opposite is also true; perhaps some Sheldrakian telepathic field hinders the departed populations, anywhere in the world they may be, from acquiring new knowledge not known by the people that still is at the population's birthplace.
The reality is that it is perfectly possible that a new populational settlement could differ technologically/culturally dramatically from the original population.
fwiw the statues of the Olmecs and Toltecs are short fat and squat with very negroid looking facial features.
