Austronesians and Aborigines also settle the Americas

What if these men also settle there from different directions ?

They did settle the Americas though. Aleutians and a couple Amazonian groups show the affinity.

Other direction? I don't think it'd effect the population that much beyond the introduction of the Sweet Potato that revolutionized many a Oceanian society.

Technology wise I can't say, any metallurgy is worthless to them until you reach PNG and other landmasses with substantial metal Reserves.

That is a very weird finding. I can't help wondering if what they're actually seeing is Denisovan genes or something, rather than Australian ones. Until we see more data, I'd be really, really hesitant to assume Australians got to the New World.

Unlikely, they stated that it happened less than 9K years ago but also all native Americans and Asians have denisovan ancestry.

We estimate that the Denisovan contribution to mainland Asian and Native American populations is ,0.2% and thus about 25 times smaller than the Denisovan contribution to populations in Papua New Guinea and Australia. The failure to detect any larger Denisovan contribution in the genome of a 40,000-year-old modern human from the Beijing area suggests that any Denisovan contribution to modern humans in mainland Asia was always quantitatively small. In fact, we cannot, at the moment, exclude that the Denisovan contribution to people across mainland Asia is owing to gene flow from ancestors of present-day people in Oceania after they mixed with Denisovans. We also note that in addition to this Denisovan contribution, the genomes of the populations in Asia and America appear to contain more regions of Neanderthal origin than populations in Europe (Supplementary Information sections 13 and 14).
 
I really don't think that the peopling of the Americas will ever be truely sorted out. First I have a hard time accepting the wandering hunters from Siberia just happened to stumble into an ice free corridor into the heart of North America. I think that the primary migrations happened along the coastal environments. And it mawy of been a case of groups spintering off of their parent groups as new families formed, groups of possible refugees fleeing somesort of strife. Eventually these groups would of hit an area south of the ice. The only problem is the evidence is 300 to 400 feet under water. Plus as outlandish as the Solutrian hypothosis is I don't totally discount it. After all haven't most of the Clovis Type stone artifacts been found in eastern North America. Of course that may be an artifact of where people are looking. But then seeing images of that incredible Clovis blade dredged up of the east coast makes one wonder. But I think if any people from Europe in 15000 BCE made to North America they were few in numbers and left little in the way of genetic evidence

No dna has proven it, neither has any real archaeological evidence. This is not a time to throw this in the thread; it's off topic and it's been discredited, let it go or post in ASB.
