New Study Shows Mystery 'Hobbits' Not Humans Like Us (phys.org)

According to a study published on Monday, diminutive humans that died out on an Indonesian island some 15,000 years ago were not homo sapiens, but rather a different species. The Homo floresiensis, known as "hobbits" since they looked like small humans, were found to be a distinct species based on the layers in the specimens' skulls. This discovery could be the end of one of the most heated arguments in anthropology.

Ao hobbits was an approriate name

[the_womble]

So, they were called hobbits because they look like small humans. They are NOT humans, but they still LOOK like humans, just like Tolkein's hobbits (the commonest association), so the name is appropriate.

Re:Ao hobbits was an approriate name

[sumdumass]

Would they truly be aliens if they lived here? You don't suppose they fell in love , flew to another planet to reproduce, and came back to live and die or anything do you?

Well I guess they could have died in space and just got dumped in the cave instead of space. But you would assume if that was the case you would find artifacts somewhat more advanced nearby.

Re:Ao hobbits was an approriate name

[skovnymfe]

They sent away their hairdressers and door to door salesmen and phone cleaners, and the ones that didn't die out from phone-transmitted diseases regressed to the point of cavemen due to bad hair and nothing to buy.

[ausekilis]

Or maybe they were the rejects that an alien species wanted to get rid of. They could be the Biebers or Jersey Shore of some ancient alien race. We just haven't developed the technology to get rid of said rejects.

Re:Ao hobbits was an approriate name

[neoritter]

Hobbits were humans in Tolkien's universe much closer to humans than the Orcs were to Elves because they weren't twisted by magic.

Re:Ao hobbits was an approriate name

[jellomizer]

I am curious about many mythological creatures were based off of prehistoric encounters with creatures and subspecies.

Neanderthals seem to have many aspects we would point out to Trolls and Ogres.
We have had a bunch of species that were around when we were too, many of them having divergent evolutionary traits. As humans had expanded we were in competition. And humans had the ability to win. But with such challenges, I would expect word of mouth tales about the evil monsters who once inhabited the land.

Re:Ao hobbits was an approriate name

[Marxist Hacker 42]

Neanderthals are just Basque.

Re:Ao hobbits was an approriate name

[mcswell]

Wow, a seriously bad article. Nearly everything it says about Basque (except for its being a language isolate) is wrong. E.g. "The structure of the Basque language is also very distinctive, it is said to contain only nouns, verbs, and suffixes." Hundreds of languages fit that description: having suffixes and lacking adjectives. But Basque isn't one of them; it has adjectives (see e.g. http://mylanguages.org/basque_..., or the Wikipedia article on Basque grammar), and at least two prefixes. And the article is wrong about Basque vowels (it does have the 'ee' vowel, what linguists would write as /i/)--in fact it has all the vowels that Spanish has (and one dialect has an additional one).

As for Basque being an isolate, hundreds of languages are isolates, with no known related languages.

I'm a linguist, those inaccuracies jumped out; I can't comment on the accuracy of the other points.

I suppose your posting was a joke, although the linked-to-page appears not to be.

Re:"most heated arguments in anthropology"

[Feral Nerd]

I read it as 'emacs vs. vim' kind of an argument.

The argument has been a bit more heated than that. For many decades humans, unlike all other known species, were thought to have an evolutionary tree without any branches. Over the last couple of decades it turns out that:

1) The human evolutionary tree had many, many, many branches.
2) Dwarfism in humans existed, i.e. the hobbits.
3) Archaic forms of humans existed until fairly recently, again the hobbits.
4) It turns out you can recover large amounts of DNA from ridiculously old samples and discover extinct species of humans without ever touching a shovel and scraping at dirt with a bricklayer's trowel.
5) Some of the diverse branches of the human evolutionary tree merged again when modern humans mated with archaic forms of human. Well know examples of this are Neanderthals, Denisovans plus at least a couple of other archaic species unknown from anything except DNA. Upwards of 20% of the DNA of the Neanderthal for example still exist in our genome.
6) There are a lot of surprises still left to discover, like Albert Perry's Y-chromasome which pre-dates the oldest know modern human fossil by 140000 years.

I really love it when things like this happen. Scientific communities tend to settle into a routine. They are like a bunch of people in a conference room who have dominant theories to explain much of the way things work and most of the work that still need doing is to extend and improve these theories and the oddballs with weird theories have been pushed into a corner and are being ignored. Then, just as people were settling into a routine under the fatherly guidance of the big names in the field, somebody opens the door and brings in a discovery like this or Svante Pääbo's discovery of Neanderthal and Denisovan DNA in modern humans (Ian Tattersall has been eating crow on that score ever since) or my other recent favourite contribution to the human origins debate which is Eske Willerslev 's discovery of people that were genetically closely related to modern Europeans but who lived in Siberia. It turns out that these people contributed significantly to the groups that settled the Americas, meaning that Native Americans and Europeans are actually very closely connected by genetic bonds that stretch back way, way, way, way before Columbus (as in 24000 years ago)... so here we once again have the revenge of the scientific oddballs.

Re:"most heated arguments in anthropology"

[silentcoder]

The archeologists who discovered the bones said it had all the hallmarks of a distinct homo species right from when they first discovered it. They published papers to that effect 10 years ago. This was however controversial due to the very young age of the bones. No other homo species except us is known to have survived past the last ice age, the claim that these did - and were not the same species as us - was very controversial. Especially since the fossils were so recent that it is entirely possible that humans could have encountered them (remember - most dead bodies don't leave fossils - if the fossils we have is a mere 15-thousand years old, they could have been alive as recently as 5000 or even 1000 years ago).
So a lot of scientists were understandably skeptical about their conclusions even though they were seriously thorough, they didn't publish their findings for almost two years after the discovery as they spent all that time checking and rechecking to test every likely counter-theory and only published it when all those tests were negative and they could find no other possible explanation.

That it remained controversial despite that just shows that contradicting pet theories can upset people - and sometimes, the pet theories are wrong. Interestingly, if any homo species was going to survive the ice age without our technology these guys had about the best shot. Living on a small tropical island - they probably barely even noticed it happened.

Re:"most heated arguments in anthropology"

[TapeCutter]

The bones and artifacts were turned over to the Indonesian government shortly after they were discovered by some Aussie scientists, since then getting a look at them has been extraordinarily difficult, even for the people who dug them up. Lack of access to the fossils is the reason we have been hearing arguments rather than test results. Perhaps the academic who was jealously guarding the bones has retired?

Re:"most heated arguments in anthropology"

[jeffb (2.718)]

I wish I had mod points for this.

One question, though. Did you really mean to talk about "archaic species" if they were close enough to interbreed and re-merge? I understand that there are lots of subtleties, but the concept of species as lines distinct enough not to interbreed was drilled into us pretty heavily at school...

Re:"most heated arguments in anthropology"

[ACDChook]

Species are generally considered to be separate if they can't breed to create FERTILE offspring. Lots of closely-related species can breed, but the offspring are usually sterile.

I may have used the term species a bit loosely but that also brings us to an interesting question. When have two groups of a species 'evolved apart' enough to be considered separate species? Turns out there is no hard and fast definition of this. In the old days this was done by analysing morphological differences of animals, however, recently it turns out that animals we thought were unrelated were actually genetically rather closely related or vice versa so morphology is not the best determinant all on it's own. In my opinion you have got two different species when the difference in their DNA is so great they can't produce live offspring and the ability to produce infertile offspring is then the transitional state. This means that genetics and not morphology is the best way to classify species and that is controversial. But morphology cannot be ignored. There are also cases where two different animal groups cannot practically mate due to anatomical differences even though one may be able to interbreed them in a petri dish and produce live, and even fertile offspring via artificial implanting of embryos. Are those separate species? It'a a matter of definition. Neanderthals for example are referred to as a 'species or subspecies of human in the genus Homo' in the Wikipedia article i.e. scientists are still bickering about whether the Neanderthals should be called Homo Neanderthalensis (species) or Homo Sapiens Neanderthalensis (subspecies of H. Sapiens). Personally I'm inclined to go with "can no longer produce offspring or only produce sterile offspring" as being the point when you get a new species and that still leaves us with the problem of defining a sub-species. According to geneticists Neanderthals and Modern humans were rather close to this point when the interbreeding events took place but they were still able to produce fertile offspring or we would not be carrying around H. Neanderthalensis and H. Denisovensis DNA now would we?

Re:"most heated arguments in anthropology"

[bondsbw]

More importantly, that definition leaves out the subject at hand, that past species of humans interbred and created clearly fertile offspring (considering that large numbers of their descendants are still alive and probably commenting on this forum today).

Re:"most heated arguments in anthropology"

[hey!]

Species are generally considered to be separate if they can't breed to create FERTILE offspring. Lots of closely-related species can breed, but the offspring are usually sterile.

Usually sterile, but not always, and not always to the same degree. And therein lies the rub: placing a thing in one category or another implies the difference is discrete and readily observable, but in the cases of populations of organisms differences are along a continuum.

The way high school students are taught about what a species is is simplistic; or at least it seems to be to me after years of working with scientists to support their data needs. I believe you can think of the concept of "species" as describing, not just a population of organisms, but a population of researchers studying those organisms. A taxonomic designation is a tool researchers use to communicate with each other; a division of a population into two species is dependent upon the their communication needs, not some kind of objective Truth.

Inability to crossbreed to produce fertile offspring is certainly one thing that researchers need species to tell them; if two populations can't interbreed then that will certainly force researchers to distinguish between them. But there are other reasons to recognize new species, and I've certainly seen cases where populations that can interbreed to produce entirely viable offspring have been put into two different species. Let me tell you that's a PITA for people who are keeping records. "We collected species X, species Y, and what appears to be an X/Y hybrid..."

It would be really nice if there were some simple, objective, observable criterion for generating a new species designation, but that's not how it works. The way it actually works is some journal editor accepts an article describing the proposed new species. Then after the ensuing argument a consensus is formed that some people like, some people dislike, but most people can live with. It's a matter of how people feel about the impact of the new species on their work, not some objective distinction -- although because objective distinctions like physical traits are involved I think researchers sometimes lose sight of the fact that naming a population with those traits is a mere convention. It's easier to see the essential arbitrariness of the process when you're sitting off on the sidelines watching.

So bottom line: "species" reflects the needs of researchers to communicate with each other, not some kind of objective reality. Reality can force researchers to recognize a new species, but it can't prevent them from doing that.

Re:"most heated arguments in anthropology"

[drinkypoo]

The way high school students are taught about what a species is is simplistic;

the problem is that even scientists don't agree on what a species is, and besides, if there is some reasonable basis it's genetic and they don't have enough genetics yet because school sucks. it's reasonable to provide an abstraction. the problem is that in school they teach you THIS IS HOW IT IS and not just this is good enough for now, and that is what is contrary to actual science

Re:"most heated arguments in anthropology"

[serviscope_minor]

The way high school students are taught about what a species is is simplistic; or at least it seems to be to me after years of working with scientists to support their data needs.

Absolutely, yes. The tree of life is not a tree. it's a directed acyclic (has to be causal) graph. At coarse scales, it looks very much a tree. Defining species is essentially the same as performing clustering on nodes of the tree (or leaves if you happen to be a cladist) such that the clusters represent a good compression of the graph in that the tree structure of the clusters is similar to the structure of the underlying graph.

Choosing the right cluster size and partitioning scheme, as with any clustering problem is very hard and the results will never be perfect. If the clustering is too coarse, it lacks descriptive power, and likewise if it's too fine, it over segments and the clusters aren't semantically meaningful.

Most of the time, fortunately, the clustering is easy. Humans for example, fir very neatly in to one cluster, and we look noticable different from and cannot breed with our pair of closest relatives.

The breeding thing covers most of it. Can breed -> same species, can't breed -> different species.

It's not perfect because some closely related species such as horses and donkeys can produce offspring ans sometimes those offspring are also fertile. However, they're not often fertile, the males never are and they have different numbers of chromosomes.

Then you get ring species ,where A can breed with B, B with C, C with D, but A can't breed with C and etc. A and D may or may not be able to breed depending on the type of ring.

And that's animals. Then you get plants which are all kinds of fucked up.

Especially since the fossils were so recent that it is entirely possible that humans could have encountered them (remember - most dead bodies don't leave fossils - if the fossils we have is a mere 15-thousand years old, they could have been alive as recently as 5000 or even 1000 years ago).

An encounter with modern humans is very likely. The people on the next island has folklore telling of small people in the "hobbit island". It has detailed descriptions, some with match the bones and some which can't be seen on the bones. For instance the women had long saggy breasts and to get around, they hung them on the shoulders. The folklore is mainly centered on one fact and that is those small people were extremely aggressive and they would likely kill you if you would be stupid enough to go to their island. In other words like most folklore it's a warning of "if you do this, you die", though this one might be even more accurate than most.

In Japan folklore tells of evil beings living in mountains and stuff. A good example is a mountain with a monster (forgot the Japanese names, sorry), which eats all the people it can find. In modern times the same mountain is a no-go area. Heavy rain is frequent even if the weather is good when you leave home and dying of hypothermia is a real risk. Being covered with a dense forest, dead people are unlikely to be found and even less likely considering people are warned not to go there (no traffic or local population). This mean while the explanation in the folklore is incorrect, the fact with "if you go there, you have a high risk of vanishing without a trace" is true. In other words, there is a real warning hidden inside the fairytale.

Also fairly recently scientists revealed that the terrain in the north west US was made when an inland sea bursts through a wall of ice when the ice age ended. When presented to the locals, a native to the area said "great lecture, but we knew it already. The folklore told us of this event" and digging into that aspect of the story, the folklore told of a strong flashflood washing away all tribes who didn't make it to the hilltops. Further upstream the wall itself was in the folklore and how it was a disaster that the inland sea vanished for all the tribes feeding on the fish. Gathering all the folklore came to the same conclusion as the university study of the terrain and all the info matches up.

Considering modern humans spread to Indonesia and reached Australia 50k years ago, we know from the date of the bones that they must have been in Indonesia at the same time at some point, possibly for many years. Indonesia is a big place, which makes it hard to proof that they encountered each other, but the window of opportunity is quite big. With no media or knowledge of foreign influence, the evenings were free to talk about folklore and common knowledge. A record of a major event like a different human species would live on forever and 15k years ago isn't even far from the report of the end of the ice age in North America.

Conclusion: if the folklore tells that modern humans encountered the hobbits, they most likely did. Remember folklore is to people without a written language what history books are to us. This mean if the folklore matches the modern findings, it's a good chance it's not just by chance. It would be reasonable to say "it's most likely like that" until proven otherwise.

There is so much wrong with this list of 'facts'. Way too many generalizations and half-truths.

One example, you do not "recover large amounts of DNA from ridiculously old samples" and "discover extinct species of humans without ever touching a shovel".

Having worked in a world-class ancient human DNA lab at a major university, I encourage readers to be skeptical of such statements. There is a lot of hard work both in the lab and in the field associated with these findings. Simplifying the process is an insult to the researchers that spend years on-site digging and lab workers who struggle to obtain intact genomes.

If you want a clear view of current research, you need to take the time to read actual research papers and give particular attention to the section called 'Methods'.

Also, being condescending to scientists and current research does not make you look more intelligent or 'right'. Scientific communities do not settle into routines. It is a constant discussion, as science should be. 'Opening doors' to new thought is what keeps it exciting.

Re:"most heated arguments in anthropology"

[Gr8Apes]

...It's not perfect because some closely related species such as horses and donkeys can produce offspring ans sometimes those offspring are also fertile.

And it only takes this happening once where that fertile offspring survives and a whole bunch of others are wiped out that the fertile offspring then generates significantly more DNA into the pool. Note that in this case it is likely male children or the female child(ren) of a homo sapiens female that were fertile and passed on the Neanderthal DNA, due to the current lack of observed Neanderthal mitochondrial DNA. Same for the Denisovans, etc. That interpretation is open to future data proving it wrong as more DNA analysis of the population as a whole proceeds.

One of the possibilities that fascinates me is that this lack of mitochondrial DNA evidence for Neanderthal ancestry through the female line may be because we haven't sampled enough of the modern human population; after all as atypical as it is to have your DNA analyzed, it's far, far more rare to have your mitochondrial haplotype analyzed.

Re:"most heated arguments in anthropology"

[mcswell]

I dunno about the genetics, but about the languages: A small group of nearly extinct Siberian languages (not believed to be related, btw, to Indo European languages) is quite likely related to the Na-Dene languages of North America (Tlingit, Navajo/ Dene, Slave, Carrier, and perhaps a dozen other Athabaskan languages whose names I don't recall). You can read about it here: https://en.wikipedia.org/wiki/.... And the Inuit ("Eskimo") languages around the polar regions are related. But afaik, there is no indication that any other language outside of the Americas is related to any other language of the Americas, nor is there evidence that any of the Na-Dene languages are related to any other native American languages.

The recent developements in average height, as well as within the next 100 years are not due to genetics. The timeframe for that is much too small to affect a huge population in the 100mio significantly.

They are mostly attributed to better food, lack of child deseases and (debated) growth hormons in food or other industrial substances that may have the same effect.

Re: That's the old hobbits. What about the new?

There is an inverse correlation between female hormone levels and height (in women). High levels of female hormones also correlate with large breasts and other feminine physical characteristics. Assuming adequate nutrition, small women tend to look more feminine, hence more attractive.

Lets just say this: Human is not the same as Homo sapiens. There are many members of our species that I would not classify as human beings - primarily for their lack of humanity.

Members of Homo sapiens are persons (biological into legal) and under American terminology, natural persons.

It is not sufficient for two organism types to be able to breed to be the same species, only that they have viable offspring. A mule is sterile, as is a liger.

These "hobbits" and Neanderthals, if alive today, would almost certainly be considered persons under the law. They would probably be viewed as human, but they would not be considered Homo Sapiens.

Technical and precise terms are required. Generalized words, like human, cannot be precise. Use the right tool for the job. Someone with far more brains and artistic skill could probably produce a Venn diagram highlighting this discussion
