Could Neanderthals Speak?

with 9 comments

I had an interesting debate the other day. Could Neanderthals speak? For the longest time the answer was “No!” However, this was more based on prejudice than anything else. IE when Neanderthals were first discovered it was more or less assumed they were a brutish forebear to humans. The quintessential ape-man as it were, basically because the were discovered and described in the early/mid nineteenth century at a time when it was assumed that humans were the apex of creation and nothing else approached us. And the view that Neanderthals couldn’t speak was reinforced by lack of any evidence that they even had the physical capability of speech.

In recent decades however the debate has been re-opened. For one thing an intact Neanderthal hyoid bone was found. This is a bone in the larynx, and it was essentially identical to a human’s, indicating they could make a wide range of sounds. Another recent discovery was of their ear bones, again, it indicated they could discern a wide range of sounds, substantially different than a chimpanzee for example. And it was pointed out that the nerve channel that led to their tongue was similar in size to a human’s, indicating they had the ability to shape a variety of sounds with their tongue. Lastly it was discovered that they had a gene called FOXP2, in humans this gene appears to be essential for speech. This of course doesn’t prove Neanderthals had complex language, but it certainly shows there is no reason they couldn’t, they had the physical capability to make and hear the sounds required for a complex language.

Other arguments for Neanderthal language are their tool use and lifestyles. Especially their hunting, Neanderthals were definitely apex predators, bringing down very large game in group hunts. Though recently it has been discovered they often did have veges with their meat. It has been argued that the complexity of some of their tool-making  tasks, let alone hunting large dangerous animals, would have require complex language. Still, prides of lions and other carnivores bring down large game in group hunts without language, so it’s certainly not definitive. Other arguments include recently discovered cave paintings by Neanderthals, and what has been interpreted as a flute made by Neanderthals. The flute (pictured above) may have just been a  gnawed bone though.

There are still strong arguments against the Neanderthals having complex language. For one thing they were around for several hundred thousand years but made almost no technological progress during that time. Unlike Cro-Magnons, who lived in groups of 30 or more, Neanderthals lived in small and apparently isolated bands of about ten people. There is no evidence that Neanderthals engage in anything resembling trade or other long distance commerce, which humans were fully engaged in starting at least 150,000 years ago. Only a very small number of tools found at Neanderthal sites originated other than locally, and even those few were never from more than 100km (60 miles) away. It’s been argued that these were “gifts” by adolescents trying to ingratiate themselves into a new group, there had to have been some interbreeding between groups. Nonetheless Neanderthal’s apparently primitive, isolated, and non-evolving culture does argue that Neanderthals didn’t have complex language.

The jury is still out on the issue. Basically the debate is about whether Neanderthals were another species, or another race. They did have larger brains than us, though they were structured somewhat differently. It’s been argued that compared to humans, Neanderthals were extremely neophobic, dogmatic and xenophobic. Afraid of anything new, afraid of strangers, and stuck in their ways. Yes, Neanderthals were the Archie Bunkers of prehistory.

So myself, I prefer to think they had language. If nothing else, imagine the sit-com one could base on it, a band of surly cavemen sitting around suspicious of everything:  “If it was good enough for your great great great great great grandfather, it’s good enough for you son!” or “No you can’t date that Cro-Magnon boy, those people have no respect for tradition!”

Feel free to add your own. Have a great weekend everyone.

The Makapansgat Pebble, a Mirror Into Our Past?

with 7 comments

Neat looking rock, eh? It’s about 2 by 3 inches (5 by 8 cm,) around half a pound (260 grams.) It would fit nicely in a hand in other words. It’s a stream worn piece of jasperite, a reddish rock that polishes up nicely. The markings on it are completely natural, the result of bouncing around in a stream bed. The resemblance to a human face is obvious, in fact there are three faces on it depending on how it is oriented. It’s not too hard to imagine that someone might have seen it laying in a creek bed, been intrigued, and carried it home to show around or even just because the person who found it thought it was cool looking. I’ve certainly carried home the odd looking rock in my time, as I’m pretty sure many or most people have.

So, a rock that has chance resemblance to a human face, what’s the big deal? Well, this particular rock was found in a cave, many miles from the creek bed where it was created. There’s only one way this rock got into that cave, someone had to carry it there. And this is where it gets interesting. This particular rock, known as the Makapansgat pebble or the pebble of many faces, was carried into that cave some 2.5 to 2.9 million years ago. This makes the Makapansgat pebble one the oldest known manuports in existence, an object moved from its natural context by human agency but otherwise unmodified.

My astute readers at this point are thinking, “Wait, there weren’t any humans around that long ago, so humans couldn’t have moved it.” Absolutely correct. The pebble was found in a cave that was inhabited by Australopithecus africanus, a gracile bipedal hominid that may have been an ancestor of the human race. So not only is this rock a candidate for the first known object moved by “humans,” it may be the first known example of a human ancestor exhibiting symbolic thought or an aesthetic sense. Yes, when that ape-like hominid fished this stone out of a creek, and stared at it in his or her hand and wondered at its resemblance to a face, this was the very first glimmering of what it meant to be human.

To me this is just amazing. Looking at the rock and imagining what it must have meant to the, well, ape-like person who found it. And knowing that every human on Earth might be a descendant of the individual who first gazed at this rock is pretty wild. I don’t think we can even imagine what they were thinking, and it’s a pretty safe bet they couldn’t imagine that millions of years later the funny rock they found would end up in a  museum half the world away to be contemplated by their great great great etc grandchildren. Still, we are connected in a way because then and now we can gaze at this rock and see a face, like an image captured in a  mirror for millions of years.

Granted, this is all pretty speculative. And the pebble might have been dropped there just a million years ago by a Homo erectus or another hominid, in which case it wouldn’t be quite as amazing. It’s just one of those quirky little things that make at least some of us shaved chimps think about how we got here. Especially since I don’t really want to think about where we’re going right now. Yes dear readers, I am so sick and dismayed by so many current events as we slide into the radioactive zombie apocalypse that I can’t bring myself to write about them now. So in the near future I am going to post about weird old things. Lots of fun to be had there, especially since I’m getting to be a weird old thing myself.

Have a great weekend everyone.
