WASHINGTON (AFP) - Researchers announced Thursday that they have sequenced the mitochondrial DNA of a Neanderthal, using genetic material recovered from a 38,000-year-old bone.
Scientists said the breakthrough, published in the August 8th issue of the scientific journal Cell, will help resolve lingering questions about the genealogical relationship between the prehistoric hominids and modern man.

Marrow ping.
So now we’ll know if red hair really did come from Neanderthals.
Hmmm... One would hope, but has anyone mapped the Democratic genome and compared it to Neanderthals? I suspect some disturbing similarities may emerge. ;-)
Modern humans and neanderthals apparently did not interbreed. I went into the issue thinking that there probably was some relationship, judging by the body type of certain regions, but the evidence is pretty conclusive. Neanderthals left Africa half a million years before modern humans, and when Cro Magnons got to Europe, they did not interbreed. Whether they interacted, we don't know, and maybe never will, but my bet is that there were territorial battles that our kind won, and which led to Neanderthals' ultimate demise.
In an’ out before the obligatory Helen Thomas photo...
Well, there's evolution and there's revolution.
May we be spared.
What other (than prehistoric) kinds of neanderthals were there??
Theoretically then they could identify the modern day straight line female descendant since the mitochondrial DNA is passed down exclusively by the mother.
An excellent question for which I have not an adequate answer.
Aflac!
If two animals can breed then they are the same species. If they say Neanderthal and man interbreed then they are saying Neanderthals WERE men.
Men the breed not the sex (smart asses)

You see one Neanderthal, you've seen them all.
Like the Neanderthals, I’m speechless.
What the DNA says is that Neanderthals and Man did not breed, or at the least, did not have offspring that survived.
Maybe they were gay and lesbian Neanderthals, who celebrated diversity and were not breeders.
I think Neanderthals caused global warming back in the day, because the earth experienced global warming which ended the last ice age. They never got their carbon credit trading system up to speed.
I met a woman while we were on vacation who has red hair and brown eyes and she claims that all people with red hair and brown eyes are all descended from the same family in a German village. She may have mentioned the village but I forget. Anyway, we talked about the ginger gene. She had never heard of that theory.
The Neandertal EnigmaFrayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]

I don’t think mitochondrial DNA has any impact on hair color.
It’s interesting that one of the theories of aging has to do with a reduced ability of mitochondria to repair themselves, because their DNA degrades.
But cellular, nuclear DNA has much better repair tools. And in fact out of the couple hundred genomes needed for the mitochondria, only about 19 actually are in the mitochondria, the rest are already in the nucleus.
So the theory is that by using viral vectors, the DNA that is prone to breaking and resequencing could be copied into the nucleus.
It’ll take more than that for somebody to ever get to their four hundredth birthday.
But not much.
We know what aging is. And soon we will be able to prevent and even reverse it.
Ping to medical/dna related stuff.
thanks, bfl
Let me know when they map the DNA of a historic one.
If they need help finding some, I’ll be glad to point them towards some likely candidates, both living & dead...or at least dead from the @$$-up.
