But can they sing? And was Dr. Zaius involved?

A research team at the Max-Plank-Gesellschaft Institute's (MPI) Psycholinguistics department has analyzed recent discoveries on humans' close relatives -- the Neanderthals (Homo neanderthalensis) and Denisovans (Denisova hominin) -- and offered a controversial hypothesis.  They propose that Neanderthals, and likely Denisovans had languages and that these human relatives likely spoke with humans during their interactions.

Recent DNA discoveries have cast new light on the interactions of humans and their relatives.

Once viewed as dumb and brooding hunter-gatherers, Neanderthals inhabited much of western Eurasia from 350,000 to 600,000 years ago, and later migrated back to Africa.  But new evidence shows that Neanderthals actually had larger adult brains than humans, a very similar genetic makeup, and advanced tool use.  What's more there is strong evidence they exchange culture -- trading with early humans -- and even more shockingly had sex with them, producing offspring.  Much of the interbreeding appeared to occur when humans and Neanderthals migrated back to Africa some 50,000 to 80,000 years ago.

The simplistic world-view was further shaken by the discovery of the Denisovans -- another ancient relative that remained unknown until archaeological finds and gene research in the latter half of the last decade.  Like Neanderthals, Denisovans appear to have enjoyed a prosperous interaction with the locals some 30,000-300,000 years ago.

The evidence of rich ongoing interbreeding with each group suggested that these genetic exchanges weren't examples of raping and pillaging.  There's strong evidence some humans on their own free will bedded these relatives intermixing their lines for long stretches of time.

MPI Professors Dan Dediu and Stephen C. Levinson say that this indicates that early man must have been able to communicate with his early relatives; they must have been capable of speech.  They argue this hypothesis is further supported by the lack of discovery of a single or handful of "magic" genes that alone "create" the capacity for speech.

Rather they argue that speech evolved between the emergence of the Homo genus 1.8 million years ago and the emergence of Neanderthals, Denisovans, and Humans common answer -- Homo heidelbergensis some 600,000 to 1.3 million years ago.

In a press release MPI writes, "This reassessment of the evidence goes against a saltationist scenario where a single catastrophic mutation in a single individual would suddenly give rise to language, and suggests that a gradual accumulation of biological and cultural innovations is much more plausible."

The researchers suggest that differences between European and Asian languages may be attributable to traces of lost Denisovan and Neanderthal languages that crept into the speech of the humans who interacted and interbred with them.  They suggest further work be done to model language spread with computer simulations and to compare the structural properties of the African (where humans interbred with Neanderthals) and non-African languages (where humans may have bred with Denisovans).

The pair have published [abstract] their paper in the journal Frontiers in Language Sciences.

Not entirely surprised...

Is this really that much of a surprise? Once genetics proved that modern humans were mating and co-existing with neanderthals it stood to reason, at least in my mind, that they must have been able to communicate with each other. And, I highly doubt that communication was limited to hand gestures and picto-grams.

Just like modern science presumes ancient man was less intelligent simply because they did not possess our level of technology, this stinks of modern man's arrogance in thinking that we were the only hominids to developed language.
