A few comments... I have an interest in the genetic sciences as it relates to our understanding of human evolution and migration. I consider
Spencer Wells and his team (
https://genographic.nationalgeographic.com/) to be at the forefront of research regarding where we all came from.
With respect to the
Aboriginal 'Stonehenge'
1) Stating that the artifacts are from the Paleolithic age is too vague. The range for the age is too great to have any significance with respect to the "Out of Australia" versus "Out of Africa". Geologically this lines up with the Pleistocene. There is no confirmation in the article regarding the age of the site, so some sort of carbon dating would be nice...
2) While timing for genetics is generally not accurate, the mutation rate of mitochondrial DNA (mtDNA) and the tracking of it throughout the world is a well established science, albeit sometime subjective as to the chronological results. That said, it appears that the mutation (deepest split) occurs in Africa, not Australia, about 200,000 to 60,000 years ago. Thus, "Eve" came from Africa. (Note is didn't say "Adam").
3) Y chromosome analysis, while complex (due to size) allows a larger range of mutations, particularly in the "junk" portion of the strand. This second method also gives weight to the argument for "Adam" leaving Africa 60,000 years ago.
It'll be interesting to see if "Out of Australia" takes hold from a genetic standpoint, but there would have to be some epiphany for that to happen.

Standard disclaimer: I'm a Petroleum engineer, consequently I deal a lot with geology
. I am not a geneticist or antropologist, paleo or otherwise
. I have an interest in evolution, which results in me reading a lot on the subject...
A humorous view of a common ancestry...
