Other papers reach similar conclusions: From the abstract of the Jungers et al. paper "Descriptions of the lower limb skeleton of Homo floresiensis":Based on rigorous cladistic analyses, we propose that H. floresiensis evolved in the Late Pliocene or Early Pleistocene. The first of our two equally parsimonious trees suggests that H. floresiensis branched after H. rudolfensis (represented by KNM-ER 1470) but prior to the divergence of H. habilis (represented by KNM-ER 1813 and OH 24). Alternatively, our results are equally supportive of H. floresiensis branching after the emergence of H. habilis. Our results sustain H. floresiensis as a new species (Brown et al., 2004; Morwood et al., 2005) and favor the hypothesis that H. floresiensis descended from an early species of Homo (Falk et al., 2005; Argue et al., 2006; Larson et al., 2007; Tocheri et al., 2007). We find no evidence of close phylogenetic relations to H. sapiens, and reject the idea that the Liang Bua remains represent a pathological modern human. Importantly, we also are unable to link H. floresiensis phylogenetically to H. erectus, rejecting the hypothesis that the small enigmatic bones resulted from insular dwarfing of H. erectus. It is surely time we accepted the reality of H. floresiensis as a species and seek answers to the questions that this species poses, not least of which is: who were its ancestors?"

From the abstract of the Larson et al. paper "Descriptions of the upper limb skeleton of Homo floresiensis":The lower limb skeleton exhibits a uniquely mosaic pattern, with many primitive-like morphologies; we have been unable to find this combination of ancient and derived (more human-like) features in either healthy or pathological modern humans, regardless of body size.
— Jungers et al. 2009
Another recent paper about the hobbit by Jungers and Baab appeared in the statistical journal Significance, and did a number of statistical comparisons of LB1. A multivariate analysis shows LB1's brain shape has no resemblance to the shape of modern human microcephalics; it is most similar in shape to fossil skulls of early Homo, especially to the Dmanisi skull D2700. The lower jaw has no chin but is instead strengthened by internal bone, similar to australopithecines, and the anatomy of some of the teeth are "strikingly primitive". The overall body proportions of the hobbit were quite different to that of any populations of modern human pygmies. The weight of the hobbit falls into the lower range of pygmies, but the hobbit's height is well below that of modern pygmies, so the hobbit "was far stockier than any modern human". Arm and leg lengths are unlike those of modern humans. The humerus (arm bone) falls into the lower range for modern humans (just), but the leg bones are much shorter than any modern humans. The ratio of the arm and leg bones was also unlike that of any modern humans, but did resemble that of another famous fossil:The upper limb presents a unique mosaic of derived (human-like) and primitive morphologies, the combination of which is never found in either healthy or pathological modern humans.
— Larson et al. 2009
To drive home the message, look at the scatter plots comparing LB1 to human pygmy populations:This extremely high ratio (around 87%) is never found in modern humans; this index is closely matched, however, in the partial skeleton of "Lucy", a famous fossil of Australopithecus afarensis from Ethiopia dated to more than 3 million years ago!

I never liked the microcephalic mutant theory at all. It depended on too many coincidences among other problems.
1. Fossil hominids are rare. Hobbits are rare. Microcephalics are rare. Multiply all those probabilities and it didn't seem too likely.
2. Microcephalics are retarded. It isn't impossible for them to survive in the stone age but it seemed unlikely. They couldn't do it without a lot of help from the other group members.
With bits and pieces from 12 individuals, it now seems to have been ruled out.
It would be nice to get some DNA to sequence. DNA has been recovered from older Homo fossils. From what I've read, they have tried and couldn't find any left.

John Hawks notes today that excavations at Liang Bua will be resumed. I don't know how long they've been suspended, but that's good news.
John Kwok · 18 March 2010
Last month I heard American Museum of Natural History paleoanthropologist Ian Tattersall fielding a question from the audience on this after giving a talk on Darwin and human evolution. He thought it was highly improbable that Homo floresiensis anything but a separate hominid species, casting strong doubt on the microcephalic mutant hypothesis.
I am especially intrigued with the potential paleobiogeographical implications of these latest papers. For decades, it was assumed that hominids didn't leave Africa until the advent of Homo erectus. Now we have to push hominid migrations back much further in time, perhaps as far back as the late Pliocene, approximately two million years ago, if not earlier.

Anyone have a graphic (or text equivalent) of the two cladograms which the study finds equally supported?
Walabio · 18 March 2010
This is not surprising. I suspect that our last common ancestor is Homo habilis. About 2 million years ago, Homo habilis left Africa and speciated into Homo georgicus. About a million years ago, Homo georgicus gave rise to Homo erectus (not to be confused with Homo ergaster of Africa). Homo georgicus is the probable ancestor of Homo floresiensis. This is mine hypothesis for the raise of Homo floresiensis:
Over a million years ago, a flood washed a pregnant female Homo georgicus from Asian side of the Wallace-Line on a natural raft of vegetation. She washed up on Flores. She birth a son. They got busy. This female would be the ancestor of all members of Homo floresiensis.
It is interesting to speculate what would have happened if she would have washed up on Australia; ¿Would Australia have Homo australicus? ¿What if Homo georgicus or Homo erectus would have made it to the Americas, would he have Homo americus today? This is fun speculation, but we can never know.

If an isolated group of Homo floresiensis were discovered living in some remote corner of Indonesia today, would it be ethical to capture some and place them in a zoo? Would they be entitled to the rights we generally reserve for humans or would they be considered animals similar to the existing non-human primates like the great apes?
Shemjaza · 18 March 2010
I’m pretty sure they wouldn’t be treated any better then Chimps by humans if we found a living colony. I doubt they’d be smart or human looking enough to allow people to fully empathise with them.
Wayne Francis · 18 March 2010
David, There is more and more of a push to give no human primates a set of rights recognised by the UN much like the human rights.
I think there would be a large out cry from all the right people if you tried to put them in a zoo or really even tried to remove them from their environment.
I would hope that was the case at least.

As to reopening the site, the question would be one for the local authorities, essentially, since government in Indonesia essentially operates on a concessionaire basis, it being understood that they've paid to be where they are, and are entitled to their perquisites. And for the local authorities, as with all government entities in Indonesia, the essential question is, "What is this worth to you?"

On the Toba eruption, tell me if I'm wrong about this (not being an expert), but I gather that the initial direction of the gigantic plume of ash etc from Toba went north-westwards towards India, ie away from any hobbit populations in (what is now) eastern Indonesia.
So the hobbit groups would have had similar chances of survival to any other hominids out of the path of the initial blast.
The following "nuclear winter", with the sun blocked out and other nasty effects, would have been pretty horrible and hard to live through, though.

YEC to the rescue.
In any issue of determining if old bones are of humans and not apes there is a clue.
The bible teaches that women uniquely have great pain at childbirth. Animals do not.
This is a great anatomical reality of our women's skeleton and so if there is a female hobbit one just needs to examine, if possible, whether she had pain at childbirth by looking at her skeleton.
If so we got a daughter of Adam. if not we got a dumb old monkey.

Back to sciences and Flores:
Check out the recent review paper by Leslie Aiello published in Early View of the American Journal of Physical Anthropology: "Five Years of Homo floresiensis". Excellent bibliography and concludes -- independently, based on the available evidence -- that the various pathology arguments all fail, and "the evidence supports the hypothesis that Homo floresiensis is a late-surviving species of early Homo with its closest morphological affinities to early African pre-erectus/ergaster hominins."
Occam's Razor · 19 March 2010
Also have a look at this week's Nature paper by Brumm et al. on 1+ Myr old stone tools from the Soa Basin of Flores. Hominins have been on that island for a looonnng time!

Mr. Byers, Sir.
You submit that animals do not have pain during childbirth? What would you say to a hyena birthing event? I won't go in to detail as it is pretty intense, so please look it up and then get back to me.

What is really interesting about all this is that some sort of scientific consensus may be emerging about the hobbit. Too optimistic?
I can't help wondering whether the doubters have yet been heard from, or if not, why not. Where are Thorne, Henneberg et al who asserted that the hobbit was merely a microcephalic human?
The other point is the good news that excavation will resume; did we ever have an explanation as to why the Indonesian government stopped it in the first place?
You get the most exciting discovery about hominid evolution in years, and you close it down!
Dave Luckett · 20 March 2010
The reason the government - more the provincial one than the central one in Djakarta, I believe - closed the site is almost certainly the same one that applies when any approval, licence or co-operation is requested of any set of officials in Indonesia. A proper gratitude has to be expressed to the relevant officers, this gratuity consisting of whatever the traffic will bear.
Delays in this process are explained by the necessity for the officers concerned to ascertain exactly how much this is.
CS Shelton · 21 March 2010
@Misha- Good points, but the reason fundies hate magic is not because children might believe it's real (and an alternative religion or such), but because they themselves do believe it's real, and it comes from SATAN. Checka the Jack Chick webpage of horrors (and crudely drawn jewish caricatures) for the haps.
On topic, I think this is very cool. Especially when Toba is factored in (something I had not thought of previously) because that makes their late survival all the more impressive. (Then again, they were outlived by orangutans...)
I saw a TV special a year back that was very convincing about the microcephalic pygmy angle, which was a bummer because the separate species angle is a lot more fun. Well good times are back baby! I love hominid diversity!

There you evolutionists go again.
Animals do not have much or any PAIN giving birth.
Woman do. In fact to explain this they invoke that walking upright was a origin for the unique pain of woman. Then they add about the head and shoulders of human infants.
In fact apes do not have pain kile humans. I was introduced to this by a national geographic issue actually.
If these are the reasons for human birthpains then how possibly could apes have like pain?
Special cases of problems with animals is not a accurate sample.
Watch any nature show where creatures drop their young and one will note little irritation.
Its possible domestic creatures have more problems because of artificial selection to grow them unnaturally big. Even still farmers never had that much too do.
Anyways the reason for the pain is in the physical body of the woman. So by looking at a skeleton one should be able too tell, I think, if childbirth was a great pain event or not a big deal.
Hyaneas? All the creatures and this is the only one? A special case and probably a second birth is of no consequence.
Anyways you guys are very wrong here and not understanding principals of your human evolution.
bY the way the writers would expect their readers to understand there is a great difference because they were so close to nature.
In fact a critic would explain away the birthpain story as a needed explanation for the difference people noted.
Dave Luckett · 23 March 2010
Two falsehoods, Byers, and you're meeting yourself coming back. Female mammals, generally, have easy parturition, but it's neither painless nor foolproof. Childbirth in humans has to cope with two further difficulties that don't apply to other mammals - bipedalism and large-headed infants. Both make childbirth more difficult and painful - and dangerous.
There are a number of partial solutions found by evolution. Lower birthrates, for one, which allows greater parental care. Humans are born totally helpless, with bones not fully calcified, their skulls unfused, their brains not yet fully functional. (This enforces parental care.) Human society is founded on sexual pair-bonding, thus providing two carers for infants. And humans are relatively long-lived, providing a generational resource to the same end - grandparents.
But the difficulty, pain, and danger of human childbirth is explained by evolution - the fact that our bipedalism and large skull capacity are relatively recent developments, occuring since our divergence from the ancestral line which leads also to our closest relatives, the chimpanzee and bonobo. The solutions to our problems are a mixture of anatomical compromises and social rejigging that shouts "workaround". Or "kludge", if you like. It isn't an intelligent design. It works, sort of, and that's enough.
Oddly enough, Genesis has an explanation, which is more than ID does. Painful childbirth (and having to work for a living) are the curses of God.
Well, maybe they are. There's a metaphorical truth in it. To get brains that can work out systemic ethics - the knowledge of good and evil -, and to get hands that can use tools, the price was difficult, painful childbirth. But if God exacted that price, He did it through the process of evolution, not because he got pissed off one fine day in Eden. Pace those who discount Him altogether, but for my money, I'd say that if He's there at all, He doesn't do things off the cuff like that.

Humans are apes, Byers, and there is a demonstrated, continuous pathway between our ancestors and ourselves that doesn't have a big red dividing line anywhere on it, apes one side, humans the other. Your invincible, malicious ignorance, your foolish denialism and the inviolable bone fortress that is your skull doesn't change that fact.

Hey Byers,
Let's see if you'll answer this one. Exactly where among the ancient (for you, only about 6K yrs.) continuum of "apes" and "humans" do YOU draw the line? You can easily find a listing of pre-human or proto-human species on Wikipedia.
Which ones were human and which not? Cro magnon? Neandertalensis? Heidelbergensis? Australopithecus afarensis?
Please explain your reasoning for determining which are "ape" and which "human." YOUR REASONING, not stuff copied from AIG or the like. Surely with the Bible as your guide you can tell a Man with a soul from a beast.
Stephen Wells · 29 March 2010
There are quite a lot of ichthyosaur fossils showing death during childbirth; they were viviparous.

Neanderthal DNA has been extracted and sequenced. It showed that H neanderthalis was a different species to modern H. sapiens. "Just people" is a description that satisfies Byers, because Byers has no clue, never having bothered his head for a moment about DNA or, for that matter, a definition of "human". It doesn't satisfy scientists, who do.
While you're demonstrating your ignorance, Byers, let's have your take on H. erectus as well. That'll be good for a laugh.
Yes, Byers, we have learned something from you. It is that you are delusional, incapable of learning, and equally incapable of logical or even coherent thought or expression.
Nomad · 30 March 2010
Byers, I'll just point out that the question specifically asked you to explain the reasons for your categorizing. Not simply what you say goes where.
Those of us observing this can't help but notice how you ignored that, simply giving your pronouncements without any sort of explanation of what reasoning you used to arrive at that conclusion.
Because you have none.
Kind of like how your response to the issue of animals and pain in childbirth is just to keep saying they don't have it. You have no source of evidence other than the bible, which as we've covered also says that rabbits chew cud. And don't even get me started on how you can influence the coloration of an animal's offspring by putting it near similarly colored surfaces.
Your bible is demonstrably wrong, and you have nothing else to cite so you keep making unsupported assertions instead.

DS · 4 April 2010
So, according to Robert, the fact that women evolved from walking on all four limbs to walking upright accounts for the fact that they have pain at childbirth. This in turn can be used to tell the difference between humans and animals. This means that there is only one species of humans and everything else is an animal. Therefore, there are no intermediates in the fossil record. Therefore humans did not evolve! Do I have that about right Robert?
Man, real scientist should of anticapted its such a stunning just wiki argument. Anyways my point was that there are now medications that can help with problems like yourses. The real reasons for this is not a mystery. They cannot be teaching you englishes but they can help with the voices.
