The English media is full of articles about the Dmanisi fossils, based on a talk by David Lordkipanidze at the British Science Festival. The articles mention the discovery of five or six specimens, with some giving the impression that these are new discoveries. The New Scientist commented that "it's not clear whether Lordkipanidze was presenting new data, or simply wrapping up the story so far for a more lay audience at the festival." However some of the other newspapers such as the Guardian clarified that most of these fossils were discovered early this decade, along with another recent discovery that is not yet published. According to The Times, this recent find is "a fifth well-preserved skull, the most complete yet", which will make it a spectacular fossil. This is probably the specimen shown a photo in many of the articles, still half-embedded in rock.
As is usual, a number of newspapers somewhat overstated the significance of the find, especially the Daily Mail with its headline "Ancient skeletons discovered in Georgia threaten to overturn the theory of human evolution". This is highly misleading. The Dmanisi fossils are a tremendous discovery, and may well change our ideas about some details of where, when, and how we evolved, but they're certainly not going to overturn the idea of human evolution. They are actually superb evidence for human evolution.
The Dmanisi hominids are from the country of Georgia (http://www.talkorigins.org/faqs/homs/d2700.html). A number of skulls have been found so far, ranging from about 850 cc (the lower end of the H. erectus range) down to 600 cc (well into the H. habilis range). In 2007, details of some skeletal material was published.
The brain sizes of these skulls straddle the gap that creationists like to claim exists between humans and australopithecines. The skulls are also intermediate anatomically, looking like primitive H. erectus skulls with some habilis features. The same is true of the skeletal material: the creatures were indisputably bipedal, but have a number of primitive features.
Naturally, creationists don't have a clue what these fossils are. Some of them think they're humans, some think they're apes, and, as I blogged last year, they're both wrong:
Dmanisi fossils - more transitional than ever
Dmanisi and Answers in Genesis
Note: In the initial version of this post, I thought the articles were referring to new fossil discoveries, which turned out to be (mostly) not the case, so the post has been corrected accordingly.

Ah, HA! A whole new set of gaps for Derwoodists to explain!!!1111!!one!!

Just waiting for some bonehead comment about the southern state. It'll happen.

The second media report is by far the worse spelling of "Guardian" I've seen. I don't think they could get "Telegraph" from their name, even in the halcyon pre-word processor days.

I followed the trackback that was supposed to be for the Telegraph, because they recently published a truly disgusting piece on the five best arguments for creationism (see Pharyngula about it.) The trackback actually took me to the Guardian-- and a truly disgusting headline about how the new fossil find "challenges theories..." For pity's sake, they couldn't say, "fills gaps..." or "completes picture..."? They just HAD to set up a quote-mine?
For a moment, I thought that AiG or the Reconstructionists must be spreading some serious dough around the British press. But then, I remembered the immortal words of Humbert Wolfe:
You cannot hope
to bribe or twist,
thank God! the
British journalist.
But, seeing what
the man will do
unbribed, there's
no occasion to.

(sigh) the links to the newspaper articles have been fixed.

So they were bipeds? Luckily. Must have been difficult hopping around before the 2d leg evolved. How long did that take, in earth-years? (Wikipedia rightly avoids all reference in "Human Leg" to evolution/avoidolution.But then it's obviously part of the Conspiracy.)

Did anybody else read this as "More Dembski Skeletal Material". Is novparl a Poe? I can't believe that he would expect legs to evolve separately.
Richard · 11 September 2009
Am I the only one who read the title as “More Dembski skeletal material?” I couldn't wait to see what he was up to now.

Well around here we refer to him as Edgar Allen if that gives you a hint. Like water, if you just ignore him, he will eventually go away.

Get a sense of humor--novparl's comment is clealy a sardonic poke at a creationist objection to evilution.

I don't come here often enough to recognize poster's names, but when I read Novparl's post, I thought it was a satire of creationism, playing on and exaggerating Comfort's idea that after a male of a new species evolved, he would have to wait for a new male female of the same species to evolve before he could breed.
But some people think he is serious? Could anyone really believe that a quadrupedal animal would give birth to an animal with three limbs, one of which was a leg adapted for bipedalism, and then have to wait to fro the second leg to 'evolve' (whatever that would mean in that context)? Surely not?
Helnea · 13 September 2009
Stanton--your post speaks volumes. No one who had completed even a year of Latin could write 'sequitor' for sequitur.

Ignore Nov. He's sort of like the guy of whom Groucho Marx said that not listening to him was a liberal education.
He's floridly irrational but harmless, and he does serve a purpose. People read his posts just to savour the museum-quality crackpottery, and the good thing is he makes biblical-fundamentalist creationists cringe, too. After all, having someone like Nov on your side would give anyone cause for doubt.
ben · 13 September 2009
Wow, Helnea really nailed you Stanton. Apparently your claim of fluency in Latin, which you never made and which would be irrelevant anyway, has been shown to be a big non-lie. For shame.
Helnea, I'm quite sure you've never misspelled a word; congratulations on being perfect. Could you take a moment to expound on what "volumes" are spoken by Stanton's error, apart from the fact that you now "know" he didn't complete a year of Latin? So far you're only up to 15 words on the subject, perhaps those "volumes" could be fleshed out a little.

I, too, was confused by the media claim that these were new fossils about to "overturn theories of human evolution." I think the initial find was first announced in 2000 - nearly a decade ago - and summed up in Lordkipanidze et al. 2007. Postcranial evidence from early Homo from Dmanisi, Georgia. Nature Nature 449, 305-310 and one or two other papers of around the same vintage.
As for novparl, that comment seemed out of character to me and very much like a Poe finally coming out of the closet.
tfk · 13 September 2009
I apologiize for casting aspersions on anyone's sense of humor. I just thought that the one leg comment was particularly droll, both because it's an exception to Poe's Law (it IS beyond belief) and because the counterargument is so simple (quad to bi) that it immediately comes to mind for anyone familiar with the more complex arguments against irreducible complexity. If novparl is a troll, he failed at Poe, but he succeeded at satire (even a broken clock is right twice a day).

You're getting tangled up in quibbles about legs, when it's obvious that the problem is feet- when did Man get a sole? Perhaps it was only originally long lasting rather than immortal, but we definitely need more intermediate fossil metatarsals to determine the point at which hunmans became capable of sin.
And Georgia? That must have been a long time bacjk in evolution, after Arkansas, but before Noo York and long before California...
