If you call that a civilization.

Nonsense.

"...progress showed that around 50,000 years ago they reached Sahul - a prehistoric supercontinent that once united New Guinea, Australia and Tasmania before they were separated by rising sea levels."

Blame it on global warming.

I guess it depends on your definition of civilization. The field genetics is finding some fascinating stuff. This out of Africa migration theory points to a migration some 100,000 years ago where a large number of migrants diverged east and west somewhere around Israel. Those who went east traveled across Asia and into the Americas. Those who went west settled Europe. Those people didn’t meet again until Columbus discovered the New World.

Tracing the Papuan and Australian groups' progress showed that around 50,000 years ago they reached Sahul - a prehistoric supercontinent that once united New Guinea, Australia and Tasmania before they were separated by rising sea levels...

There is a very large rat running around in this learned study. Let me explain.

Based on actual events, the Earth has not only experienced this rise in sea level, but has prospered and flourished after it. Enough of a rise to separate Tasmania from Australia.

And yet, just a few feet of speculative sea level rise from "climate change" is going to produce CATASTROPHE.

And inquiring minds want to know: how many coal mines did we have to shut down 50,000 years ago to stop this sea level rise? How many jobs did we have to kill?

Oldest continuous and uninterrupted genetic enclave, maybe.
Civilization - nope. They never had agriculture.
