Mungo Man, an anatomically modern skeleton, was discovered in 1974 in the dry bed of Lake Mungo in New South Wales, Australia. The skeleton made the news again recently when scientists dated his remains to 60,000 years ago. Mungo Man became the oldest human fossil that was physically similar to modern humans. But further analysis of Mungo’s mitochondrial DNA (mtDNA) could not link him to any human population living today.
That is literally an impossible condition, as all humans share some percentage of DNA---so Mungo Man HAD to have some percentage of DNA overlapping modern humans. The question is "what percentage".
Wow! Mungo Jerry went back much further than I remembered!
