ditto on the outback--It is that kind of place, I've known a couple, where there is the unmistakable feeling it was very different than it is today.
Key passage:
The Australian National University team looked at the DNA found in the mitochondria of these ancient people's cells. mtDNA, as it is known, is inherited only from females and also mutates - errors appear - at a steady rate, meaning it can be used as a "molecular clock" to investigate human history.
But the Australian researchers contend that the DNA sequences isolated from Mungo Man's bones show him to have a genetic lineage that is both older and distinct from this line.
Given the undoubted modern appearance of Mungo Man, they argue, major doubt must now be cast on the so-called "Out of Africa" hypothesis in which all living people are said to be descended from a group of modern humans who left their African homeland no earlier than about 120,000 years ago.
