I was looking to a five parts series "First peoples" about the raise of Homo Sapiens and saw now the fourth episode about Australia.
Especially for MM you can still see it on Arte in French
https://www.arte.tv/fr/videos/050567-00 ... anete-1-5/
But it seems to be originally published by PBS
And for the interested English speaking friends I found for the time being (till it is discovered?) I think the first three episodes

About the series:

In the series they said that as the first Homo Sapiens was very isolated once he was jumped to the Austrialian continent and by the isolation and the great distances between the colonies, there was a danger of extinction, while the gene stock became poorer by the intermixing among a small population and hence danger for extintion, but that was countered and at the end saved by the long distance exchange and commerce and by that mixing of the people and renewing of the gene stock.

I searched on the net, but perhaps as the new scientist approach is very new: from 2010 on I met perhaps that many contradicting, even scientifical work...?

And when arrived the new Homo in New-Zealand Caro?

I will try to see something more coherent on the internet for tomorrow...at least the series that I watched till now the 4th episode was very coherent...in the series it was said that the Homo Sapiens arrived even earlier in Australia than in Europe...

Kind regards from Paul.

Whilst the precise dating of scarce remains and whether one can classify them as being from anatomically-modern humans are still subject to much debate, it has long been known that humans (ie homo sapiens) have been in Australia for a very long time. Archaic but anatomically-modern humans seem to arisen in west Africa around 200,000 years ago and then spread outwards through the Middle East and into Asia. To date the earliest remains of such humans in Australia are from about 60,000 years ago, which is roughly the same time, or indeed slightly earlier, than the earlist remains from humans in Europe north of the Mediterranean.

At this time extensive glaciation meant that sea levels were perhaps as much as 100m below the present level and accordingly land masses were more extensive, there were numerous 'land bridges' between the islands of the Indonesian archipelago, and New Guinea was joined to northern Australia. Nevertheless for humans to migrate from southern Asia down to Australia they still had to traverse extensive areas of open sea. The same climatic conditions, with extensive ice sheets covering much of Europe, probably accounts for why humans got from Africa to Australia before they got from Africa to Europe. 

By contrast humans first arrived in New Zealand from Eastern Polynesia around 1300, ie just 700 years ago.

MM, thank you for your comments and also as Caro said the recent introduction of humans in New Zealand.

"At this time extensive glaciation meant that sea levels were perhaps as much as 100m below the present level and accordingly land masses were more extensive, there were numerous 'land bridges' between the islands of the Indonesian archipelago, and New Guinea was joined to northern Australia.

Yes it is all in the documentary. I see now that the French Arte link doesn't work anymore, but you can still see the links of PBS that I mentioned. I hope you find the time and are interested enough to watch them all...nearly three hours...I hope that they for each one as in New Zealand can be watched as I present the links overhere? For instance in your neck of the woods?


And the inhabitants had to cope with these rapid natural environment changes...and as the people got dispersed in small centra and as I mentioned it was thanks to their long distance exchanges and hence mating that all these small entities didn't disappeared due to inbreeding and an extinction of humans on the Australian continent...

Another new insight that I learned in the series...
When the Homo Sapiens met for instance the older Denisova in Asia, this older one had already evoluted due to adaptation to the environment the "normal" way and when Homo Sapiens mated he received already a lot from the Denisova to coop with the new environment, while short shunting the evolution that he couldn't adapt to normally in such a short time...

When we were at the BBC messageboard I remember 2008 and the research of the Max Planck institut in sequencing the DNA from bones of the Neanderthaler if I recall it well...so the documentary is speaking about new discoveries all very recent of the last ten years...altering whole fields of science of before...

Kind regards from Paul.
