If it is a member of our genus then it was more likely H.Erectus than early H.Sapiens most DNA evidence points to a group of about 75-100ish modern humans arriving in America about 40000-50000 years ago or at least the group that survived did.So this thread is about discussing the first homo sapiens, who left Africa about 100,000 years ago to Asia. But new discovery points to human activity about 130,000 years ago in North America? How did these people cross the Atlantic? how did they survive the harsh weather in Russia and then Alaska? according to the paths (as traced by scientists), that's a fairly difficult route to take via Alaska.

The mainstream view of early humans is changing all the time.

That figure for Neanderthal DNA in humans is for Europeans and Asians. Sub-Saharan Africans have none.
Though research now says Sub-Saharan Africans aren't pureblood H.Sapiens either. All modern humans are hybrids of one kind or another.
Much older Hominin species that interbreed with ancestral Sub Saharan Africans than Denisovans or Neanderthals though.
Yes. They think Africans have interbred with another as yet unidentified archaic hominin species, and also Melanesians with a different missing species. Just going by the traces in the DNA.
I don't think there is such a thing as a pure bred H. Sappiness left. We are sort of the hybrid species that emerged and dominated the planet. This will no doubt upset a lot of racist ideologists, but these are the facts. Also, early Europeans were likely dark skinned with blond hair and blue eyes.
Interesting. A couple of things came to mind.Interesting development: Ancient butchered rhino suggests humans lived in the Philippines 700,000 years ago
Obviously long before humans were thought to inhabit the region and these dates continue to be pushed back!
sounds like Homo Erectus. Considering they got into the Indonesian archipelago (that is where Erectus was first discovered) no reason as to how they couldn't get to the Philippines.Interesting development: Ancient butchered rhino suggests humans lived in the Philippines 700,000 years ago

You're probably right. Here's another find: 50,000 year old Siberian bones (may be Homo Sapiens or Neanderthal)sounds like Homo Erectus. Considering they got into the Indonesian archipelago (that is where Erectus was first discovered) no reason as to how they couldn't get to the Philippines.
Older ones could also be Denisovan. Hope they are so we can start putting together a picture of what they even looked like. All we have are a few finger and toe bones.You're probably right. Here's another find: 50,000 year old Siberian bones (may be Homo Sapiens or Neanderthal)
I think they have even less than that, a small part of a phalanx (Finger bone) and a few teeth. If it wasn't for the ability to study the DNA we probably never have recognized these as a different hominid. I'm not sure the toe has been proven to be Denisovan. Nature had a fairly good summary from a few years back about the rootin' & tootin' our ancestors got up to - http://www.nature.com/news/evidence...=862269052&spReportId=ODYyMjY5MDUyS0Denisovan.Older ones could also be Denisovan.

Neanderthals and Denisovans are extinct groups of hominins that separated from each other more than 390,000 years ago. Here we present the genome of ‘Denisova 11’, a bone fragment from Denisova Cave (Russia) and show that it comes from an individual who had a Neanderthal mother and a Denisovan father. The father, whose genome bears traces of Neanderthal ancestry, came from a population related to a later Denisovan found in the cave. The mother came from a population more closely related to Neanderthals who lived later in Europe than to an earlier Neanderthal found in Denisova Cave, suggesting that migrations of Neanderthals between eastern and western Eurasia occurred sometime after 120,000 years ago. The finding of a first-generation Neanderthal–Denisovan offspring among the small number of archaic specimens sequenced to date suggests that mixing between Late Pleistocene hominin groups was common when they met.
Wow.An important find: DNA reveals ancient girl from Siberia had Neanderthal mother and Denisovan father
That's the conclusion of anthropologists who analysed a 50,000 year old leg bone fragment found in a Siberian cave in the Altai mountains. Here's the abstract of their paper which was published in Nature:
I agree.Wow.
The Melanesians in New Britain and New Ireland can have ginger hair, many of the kiddies have bright ginger/blonde hair that often, but not always, darkens as they get older. When I was there I assumed it was due to an injection of European genes, but it has been shown in recent years to be a separate de novo mutationI've always thought of Denisovans as the Neanderthals of the Oceanic region.
I consider Oceania (South East Asia, Micronesia, Melanesia, Polynesia, Australia, New Zealand) to be the most interesting area on Earth. I think it was the last area on Earth to truly be discovered and explored.
More than anything the population genetics of the region fascinate me. Specifically from a superficial, phenotype perspective. So many different, unique populations with traits that resemble both the darkest of Africa and the lightest of Europe. A full-blooded Aboriginal with hair textured like Europeans, skin dark as a Bantu, with a broad denture palate to match. A brow ridge that only certain European ethnic groups could match. The peoples of the Oceanic region connect us all together.
Didn't even mention the blond hair of Melanesian populations. Hell some ethnic fijians can be thrown in the states and pass of as African American. Two groups from entirely separate areas of the globe. Divergent evolution.
I am pretty sure some Australian Aboriginies can get a level of rufousity in hair color too.The Melanesians in New Britain and New Ireland can have ginger hair, many of the kiddies have bright ginger/blonde hair that often, but not always, darkens as they get older.

Interesting find. Her old man had aboriginal in him as well.
We've already known Australians bred with siberian denisovans long before the out of Africa theory begun.
Cool story bro ..No.
Not as far as I'm aware. Australian aborigines are fully modern humans, the vanguard of the out of Africa migration around 70-80 thousand years ago that reached Australia by at least 50 thousand years ago. Interbreeding with Denisovans seems to have happened somewhere near the Wallace line, perhaps even east of it, not in Siberia. It is thought the migration route to Australia was along the warm coasts of southern Asia, not north of the Himalayas via freezing Siberia.
Interestingly it is Melanesians from the modern day PNG area that seem to have the highest proportion of Denisovan admixture in their genes.
