Antarctica split from Australia about 96 million years ago, in the early Cretaceous Era. Antarctica was covered in ice by 25 million years ago, about the start of the Miocene Era. The first hominids don't show up until about 4 million years ago, in the middle Pliocene Era.
I find it somewhat implausible that Australopithecines evolved from seals on the edge of an ice shelf and swam 3,500 miles to Africa hunting penguins, or whatever..
My recollection is that mtDNA studies showed at least no female Neanderthal ancestry for modern humans - strong evidence against this "One Species" proposal.
Shh, don't confuse them with facts.
AFAIK, there are no animals or plants or even viuses on Earth that have DNA made from anything other than Adenosine, Cysteine, Guanine, and Thymine.
So any argument about "species" is kind of lame and has no meaning.
Life on earth is based on the above. Any proteins or amino acid complexes that are different are ruthlessly attacked.
Perhaps we are a bit too proud of ourselves. Something like 90% of living beings on earth are too small to be seen by the naked eye, they are bacteria.
And 80% of those live undeground or in the oceans.
Hmm.. I should not have said "10,000 BC Siberia or Polynesia" because Polynesia wasn't settled until after 1600 BC (beginning with the Solomon Islands, and that is more strictly Melanesia). I should've said Oceania, and I was thinking New Guinea and Australia, to be exact.
I would say we aren't nearly proud enough of ourselves. My prediction is that that will change within 10,000 years.. Prove me wrong! =)

Rib bones?
Does it matter?
If your daddy lost his index finger way before you were concieved, I'll bet you have two of them.......
(Or is this a 'horse' toes type of question?)
Well, you had to post it on Christmas Day when I wasn't at the computer to stir up trouble!
Actually, evolution says that when you have enough data available to you it *should be* hard to say where one species leaves off and another begins. But, as Ichneumon has explained already on this thread, Henneberg's analysis is more naive than insightful. It makes fun newspaper copy but don't expect it to win much influence.
Exactly.
Actually there is, but I bet you can't figure it out. Hint: it doesn't require any scientific training.
I remember how astounded I was a few years back when I read the report that they had found chemosynthetic bacteria in solid bedrock something like 25 hundred feet down.
I imagine that limit itself has been exceeded, next they will find chemosynthetic pyrophilic ones even deeper.
No. It's a question you obviously don't understand.
"Bacterial spores have recently been brought to public attention, following the use of these organisms for warfare purposes and the exciting report of viable 250-million-year-old spores (35).

Yikes! I read the article, it didn't say how they found them. I know they have found viable archeobacteria in the guts of insects trapped in amber.
I'm a bit spooked by something that old. Modern lifeforms might have lost all resistance.
