When did modern Homo sapiens first disperse to Australia and the Americas?

Question

From what pre-existing populations did these people come? What route did they take? What innovations were required for them to make the journey?

Answer 1

The first indigenous peoples of the South Pacific were Aborigines, or Maoris. There were many types of peoples that migrated from all over Asia Minor and Micronesia, got in their canoes or other water craft and became residents there in New Zeland, Australia and other nearby areas, like Indonesia as well. Much, much later there were criminal outcasts from European countries that were banished to the large Island/continent or Australia. Then after that came the Sydney Ducks. (That's a story for another time).

Answer 4

You notice that the "Out of Africa" theory has to be paid homage even in migrants to Australia.  It is silly.  There were hominids in Asia for over a million years.  The limit of Carbon 14 is about 45 thousand years and that is the limit of many archeological sites.  They simply don't dig deeper because it extends beyond the effective dating and because digging deeper is often expensive and dangerous.  Most archeologists are not trained in mine shoring (not that well trained anyway).  It tends to leave the theories around 40 thousand years.  I personally agree that 40 thousand seems about right for Americas and probably 60,000 for Australia but would not be surprised if it extends much further back.  The lack of fossil evidence doesn't mean very much in this case in my opinion.

Answer 5

You asked WHEN, did modern Homo Sapiens arrive in Australia & the Americas....

Australia was first discovered by Aboriginals probably not early than 60-65,000 years ago, by migrants from Africa, who traced the shoreline around India (Because fresh drinking water empties into the ocean), and first rafted to New Guinea, and then to Australia. They probably could see each subsequent land body that they wanted to explore ahead of them, and used simple rafts with oars...

North America probably wasn't entered, prior to about 32,000 years ago, by indigenous Siberian/East Asian people, crossing the Bering Land Bridge (which was 600 miles wide at the time/1000km). They likely followed herd animals, which was their food source.

From North America, various tribes spread out, some migrating as far as South America. The oldest known remains were found on the Gulf coast of Mexico, dating to 28,000 years, before the present time...

Answer 6
