It's difficult to believe that anything can pass down unchanged, though, for a thousand generations. Is that really possible?
No, it isn't.
These stories, fascinating as they undoubtedly are, are no more a description of anything real than the book of Genesis or the Works and Days or the Mahabharata. Over a very few generations the stories change out of all recognition, at least with regard to any useful details. They serve a religious function, justifying certain behaviours and outlawing others; an identifying function, giving people a sense of themselves and their history and importance; an entertainment function, the evenings can be very long and tedious there; a political function, giving a natural and unanswerable rightness to the customs of the group, which is very useful to those who want to control it.
Every change in the leadership, every battle won or lost, every time a part of the group fought with another and left to make it's own way, every migration, every alteration of the accepted circumstance, needs a new set of foundation myths, which some- call them shamans, call them politicians- will be happy to provide. No, these stories, myths, customs, laws etc have not survived intact through 1,000 generations.
I know it's a bit much to expect a journalist to consult someone who knows something about the subject before writing an article, but a bit of input from an anthropologist would have stopped him making an idiot of himself. Or, indeed, a bit of thought.
There have been humans in Australia for at least 40,000 years, that much is true, but linguistic and other evidence suggests very strongly that for much of that time they were concentrated in the northwest, close to the coast. A thousand generations ago the ancestors of 'John', who, despite being an adult Australian educated by missionaries speaks English like a Hollywood Indian of the 1950's (not the only example of casual racism in the article), certainly did not live anywhere near Alice Springs. It is highly unlikely that anyone did.
Why does he think that 'no other humans can claim this'? As I have said, 'John''s tribe can't claim it anyway, but people have lived in East Africa since there have been people, and in Southern Africa for far longer than they have lived in Australia.
Better told, it would have made a good story, but no more than that. There is nothing it can tell us.
