A new member of the human evolutionary family has been proposed for the first time based on an ancient genetic sequence, not fossil bones. Even more surprising, this novel and still mysterious hominid, if confirmed, would have lived near Stone Age Neandertals and Homo sapiens.
“It was a shock to find DNA from a new type of ancestor that has not been on our radar screens,” says geneticist Svante Pääbo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. These enigmatic hominids left Africa in a previously unsuspected migration around 1 million years ago, a team led by Pääbo and Max Planck graduate student Johannes Krause reports in a paper published online March 24 in Nature.
The researchers base their claim on DNA from a finger bone belonging to a hominid that lived in the Altai Mountains of central Asia between about 48,000 and 30,000 years ago.
Anthropologists have generally assumed that hominids left Africa in a few discrete waves, starting with Homo erectus about 1.9 million years ago. Neandertal ancestors left between 500,000 and 300,000 years ago, followed by humans around 50,000 years ago.
But the new genetic sequence supports a scenario in which many African hominid lineages trekked to Asia and Europe in the wake of H. erectus, Pääbo suggests.

Welcome wagon ping.
And he should pick up his Grant Money where???
Almasty (or yeti) ping?
Makes lots of sense as Blam has postulated. Now we need to
find ruins under the gulf of Thailand. Most interesting news in a long
time.
The new evolution family shall be called “El Liberals Erectus” and now we know where they came from.

Nice hypothesis, I suppose. But how will the idea ever be tested? How can this be substantiated in any way?
I see this as little better than stoned college freshmen sitting around saying, "Wow, wouldn't it be cool if ...". But real science should operate at a slightly higher level than that.
Evidence supporting the Theory of Evolution is everywhere around us.
Very neat information thanks for the post
No... actually mDNA has nothing to do with computer models nor with phony baloney predictions. It is at least an attempt to get at the truth which is more than I can say for other forms of beliefs.
Why is it a shock? These people claim to be scientists. Basic reason suggests that given the limited preservation of homanid remains it would be ridiculous to assume that the accumulated discoveries of the past 100 years would be all there is.
How amazing is that? And every one studied so far had DNA.
I've worked with all of these guys.
Assuming that any theory about the things we see from earth’s past can be substantiated today by the scientific method is folly. We can’t observe any of the actual phenomenon that caused these changes.
However, theories are postulated and then accepted as scientific fact. Those who argue those facts are labeled “flat earthers.” What is interesting is that over time, they often change the “facts” to fit new “discoveries.”
It does sound like global warming :)
