Clarence writes "After some 30,000 years of silence, the Neanderthal race is once again speaking thanks to some advanced computer simulation. A Florida Atlantic University professor is using software vocal tract reconstructions to emulate the speech of our long-dead distant relatives. 'He says the ancient human's speech lacked the "quantal vowel" sounds that underlie modern speech. Quantal vowels provide cues that help speakers with different size vocal tracts understand one another, says Robert McCarthy, who was talking at the annual meeting of the American Association of Physical Anthropologists in Columbus, Ohio, on April 11. In the 1970s, linguist Phil Lieberman, of Brown University in Providence, Rhode Island, inferred the dimensions of the larynx of a Neanderthal based on its skull. His team concluded that Neanderthal speech did not have the subtlety of modern human speech.'"

Who would have guessed.
I wonder if early humans, such as Neanderthals, communicated primarily by speech or by a combination of speech and hand signals. The fact that human infants as young as 7 months (at the extreme) are capable of communication by signs, even before they are able to talk, suggests to me that language ability in humans might have evolved prior to the development of a modern vocal tract.
I would not be surprised, if we could go back in time, to see early humans communicating primarily by signs, with vocal communication only as a backup. After all, you don't want to make noise when hunting game anyway.

All mammals seem to have some form of intercommunication it seems though by that measure, even if it is by scent or subtle body/tail movements. Is our only difference the specificity which our language can define our environment?
I think the real difference between human communication and that of other animals is the fact that we have grammars which directly encode semantic content. An ape can be taught to sign, but the signing lacks grammar, being more a string of symbols with no clear semantic relation.
Modern sign languages are grammatical. I think the sign languages of ancient humans were probably grammatical as well. In other words, I'm speculating that grammar might have evolved before speech did.

Who the hell gave the grant for this research? Of course, you can sort of create an apparatus that follows the same constraints as a Neanderthal larynx would have followed, but apart from piping
Now, we're fairly sure that concerning syntax, early human's language surely followed some sort of predicative model - that can be seen when analyzing more isolated and primitive languages (which are mostly dead by now) - especially aboriginal languages of America and Oceania/Australia. Sentences there usually are of the form "This is an Apple. This is red." - instead of "This is a red apple". Basically they were speaking in "features", chaining them together, which resulted in either isolating languages (words have no inflection and are immutable, syntactic structure gives a sentence meaning "This apple is. This red is." Chinese works this way) or agglutinating languages (like early Nahuatl, they would incorporate subjects and objects into their words: "Thisapple and Thisred".) in the end. More sophisticated stuff, like polysynthetic languages (Inuktitut) and inflectional languages (Germanic) are thought to have evolved thereafter. But of course, this is one hypothesis and there is no way of proving any of this. You can only use fairly circumstantial evidence.
And what this guy did was in no fucking way making "Neanderthals talk". Not even close. He just explored what kind of restrictions the anatomy of a Neanderthal's speech tract would impose on their phonetics (not even phonology let alone phonotaxis), so basically, he can now say: this is what it would have sounded like, but not more. Talk about misleading summaries/headlines/articles.

This research isn't about what the Neanderthals said - it's about the kinds of sounds they were able to produce with their vocal tracts (or Liberman's models of them). The lack of subtlety is the lack of the ability to produce recognizably distinct vowel sounds.

This assumes several things. It assumes phonemes were used, for example. There's an island where the native language is communicated by whistles. The language, if I recall the article correctly, is descended from Spanish. The series of whistles constitute a series of samples at regular intervals along Spanish words, so there is a 1:1 translation between the two. Whistles, of course, do not use phonemes at all and therefore such a form of communication is not subject to the intelligability of sounds. (All I need is one example to prove that there exists a real, plausible solution that violates the assumptions made. I don't need to prove that the solution actually applied to Neanderthals, so long as my attempt to falsify really is plausible.)
If phonemes were used, then it assumes that language drifted sufficiently for a communication barrier to exist. That's more reasonable. Neanderthals didn't have that much mobility, so maintaining a unified language and accent across the entire space they occupied, over the entire time Neanderthals existed, would likely have been impossible. I can buy into the idea of there being sufficient drift to cause problems over a large enough distance, but if there is an intelligability problem and communication with nearest neighbour is absolutely essential, that drift was locked within certain parameters and (if you want to look at it in modern networking terms) could not have exceeded some limit on a per-hop basis. That might be an interesting result to have.
It also assumes that the constraints were the same. Modern languages are heavily based on very complex grammars and therefore don't need a particularly wide range of sounds or symbols. Very early written languages directly descend from pictographic systems and require a considerably greater number of symbols and signifiers. By inference, I'm going to say that very early spoken languages would also use a much wider range of sounds and fewer rules for inferring a specific meaning for a specific sound in a specific context. If that is correct, and the parent poster seems to have vastly more knowledge on this than I do so can probably answer this, it should be much rarer for two distinct words to sound alike enough to be confusing even with different accents.
The archaeologist's perspective (Score:4, Interesting)
What most people aren't aware of is that when compared by cc Neanderthal brains were, in fact, larger than those of modern humans. You and I have a mass of around 1400cc, a Neanderthal 1500cc. (a rough guess, anthropology classes were a long time ago) How much of this is extra mass is related to them having more musculature thus greater need for control, we don't really know.
Still, they were certainly smart. As far as culture goes, Neanderthals had rudimentary technology and more importantly they had ritual. Graves show that they buried their dead with flowers and other trinkets. This suggests some concept of "remorse" or even the afterlife. These are clearly human traits, so they were obviously closer to us in thinking than other apes.
On the main subject of Neanderthal language. Well, there's a theory that it is not, in fact, an extinct language at all. In northern Spain and southern France there's a strange "language islote" called Basque. As far as modern linguists are concerned this language exists in a little language family of its own, totally unrelated to any other in the global family. It certainly pre-dates the Indo-European languages that are prevalent in most of Europe. This raises another question is: What is the Origin of the Basques? Who knows?
However, it may JUST be coincidence that the last (as far as archaeologists can tell) Neanderthals lived in Iberia. So is Basque is the linguistic cockroach - staying alive when all around it dies? Who knows. There is some strange evidence. Basque people have a 55% O blood group - the highest percentage in the world, which suggests some genetic differentiation from the rest of us. In a nut shell, though, we really don't have a clue.

Isolation and polysynthesis are simply two different ways of encoding information; they put no bounds on the expressiveness of a language, only on the form that it takes.
I really suggest you read Edward Sapir's "Language: An Introduction to the Study of Speech" (available here [bartleby.com] for free). As described in that book, there is a natural tendency for languages to drift in their syntactic "philosophy" over time.

(I'm aware that this issue is a bit more complicated than this; Africans are not nearly as homogenous a group as Europeans and Asians, and some Africans are more closely related to Europeans than to some other Africans, but let's not get into that detail here, okay? My point is that all modern humans are much more closely related to each other than to Neanderthals.)
