The Final Fall of the Pre-Clovis Barrier?

New 15,500 tools found in Texas
Back when I was an undegrad and I was learning about New World archaeology, I became fascinated with the topic of the peopleing of Americas.  I loved how it involved not only archaeological data, but linguistic and genetic as well.  SFU's own Knut Fladmark had popularised a theory which I found more plausible than the common idea of the first peoples entering North America through Beringia and down through an 'ice-free corridor' down near the British Columbia-Alberta border into the States, between the Cordilleran and Laurentide ice sheets.  Fladmark proposed that first peoples could have came through a coastal migration along the coast, island hopping and living in refugia - areas not covered by mountains of ice, such as Haida Gwaii.

Haida Gwaii (previously known as the Queen Charlotte Islands) have a unique ecology because they have a few thousand years less time spent under the ice than the rest of Canada.  Apparently I've been there when I was very yound, to Sandspit, but I have no memory and would love to visit what I imagine to be Vancouver Island but a bit more rugged and desolate.

Perhaps I like the coastal migration theory a bit because as a west coast Canadian girl, it puts my homeland right in the way of the first migrations, but it also sounds more plausable for a number of other reasons.  One is that the ice free corridor might not have been open at the time - and if it was, the harsh environment between the glaciers would offer a puzzling mystery of why people ventured down between into a stormy place with no fish in the rivers and high mountains of ice on either side.  Where did they think they were heading?

Another reason I find the ice free corridor idea imnplausable is the archaeological and linguistic evidence do not support it.  The oldest accepted site (until now) in the New World has been Monte Verde, a 12,500 year old site at the bottom tip of South America - nothing near that old has been found on Beringia or Alaska.

An old undergraduate essay I wrote, back when I was even worse at academic essays, wrote about this coastal migration hypothesis and the evidence supporting it.  The linguistic evidence was one of the most interesting supporting factors.  The longer people have been in one place, the more languages and language isolates you usually find.  If one follows the ice-free corridor hypothesis, you would expect to find the most linguistic diversity in the central area of America, but you find it along the west coast of North America.

If a coastal people entered America with watercraft, it wouldn't be too suprising if their migration south was a bit quicker than overland - making the Monte Verde site less of a mystery.  But now, a 15,500 year old site, quite a bit older than even Monte Verde, has been found in Texas.  The reason this is so special, is that if people entered North America at this time, there was probably no open ice free corridor at the time.  There has been a well known resistance to sites with suggested dates that put them at a pre-Clovis date, such as Meadowcroft and Pedra Furada.  If this new site is accepted by the archaeological community though, perhaps the coastal migration hypothesis will be lent new support.

Dreams of Neanderthal Paintings at Chauvet

An article in the guardian (http://www.guardian.co.uk/film/2011/mar/24/cave-of-forgotten-dreams-review) discusses a new documentary on the Upper Palaeolithic paintings at Chauvet cave in France, called Cave of Forgotten Dreams and directed by Werner Herzog.

I looked forward to reading about this documentary, but my excitement was soon overshadowed by a glaring error by the reviewer, Peter Bradshaw.  To be fair, he is a film critic, not an archaeologist, but I'm suprised after having viewed the documentary he's still left fuzzy about who the artists of Chauvet's paintings were:

"...the extraordinary Chauvet cave in the south of France, named after Jean-Marie Chauvet, the explorer who in 1994 made a Tutankhamun-level discovery: hundreds of pictures of animals drawn with flair, sophistication and detail by Neanderthal man around 32,000 years ago."

I don't think I'm being a pedant by being offended by this error...!  At 32,000 years ago, in current understanding, Neanderthals were limited to the Iberian peninsula - and have never been associated with cave paintings of any kind.  Until recently, no form of art was attributed to Neanderthals with any consensus at all - so the attribution of this equvalent of the painted ceiling of the Sistine Chapel is a bit suprising to anyone who has had a passing interest in human prehistory.

I think this is a good example of the public perception of human prehistory, our own ancestry - we see titles in newspapers about Neanderthals wearing makeup and how Neanderthals never died out because they live on in our genes, and these are the sort of ideas we carry around in our heads about our past.  Cave men - were they Neanderthals or humans?  Did humans evolve from Neanderthals?  What was the difference?  I suspect most peoples answers deviate quite far from current (or even past) research.  Readers have picked up on the error in the comment section, but further misunderstandings about Neanderthals are quickly raised. 

Solutions?  Do we need one?  This makes me wonder how prehistory is covered in school...

NWLC update: Victoria here I come!

Merry Christmas, everyone!

Good news: my abstract to the NWLC conference at UVic has been accepted.  I wasn't chosed for an oral presentation (boo), but I was accepted for a poster presentation, and I still have a chance to submit my essay to the proceedings, which is good (although when I will find time to create this poster along with the essay while juggling a full time job still eludes me!).


Anyways I thought I'd share my abstract and welcome any feedback.  I'd also welcome any poster presentation tips, as this will be my first!



What came first, the noun or the verb?

          Language origins research supports a gradual evolution of human language in our species over a long period of time, rather than an abrupt acquisition in one step (see for instance Pinker and Bloom 1990, Jackendoff 2002, Stade 2009). An important line of enquiry, then, is to explore in what steps language likely developed, such as in the emergence of syntactic structure.
          In the literature, it has been suggested that certain syntactic categories were the first to emerge, mainly nouns ([Smith 1767] Land 1977, Li and Hombert 2002, Luuk 2009). However, theories positing a first grammatical category are problematic; in isolation, an utterance cannot be attributed a syntactic category such as noun or verb unless one uses a semantic definition of what a syntactic category is. A semantic definition of syntactic category is awkward because of language variation, and therefore in modern linguistics it is common practise to attribute a syntactic category based on morphological and distributional properties (Evans and Green 2006, Gil 2000). An isolated word without any morphology or distribution is category-less.
Luuk’s (2009) paper argues that nouns were the first category to emerge, and he offers eleven reasons why this must be so. While Luuk’s paper argues successfully why verbs are unlikely to have emerged before nouns, he has not considered that these categories could have emerged together.
          It is argued here that the first utterances would have been category-less, and it was only in relation to another utterance that syntactic categories could truly exist; hence, two or more categories must have emerged at the same time. This hypothesis is supported by grammaticalization theory, which describes nouns and verbs as being the most primitive categories as they are the least grammaticalized and cannot be derived historically from other syntactic categories (Heine and Kuteva 2007).

Evolutionary Linguistics 101

Biologists are interested in the origins of life, geologists are interested in the formation of rocks, but few linguists are interested in the origins of langauge, as Friedrick Newmeyer once pointed out.  But this is a problem to be rectified... and if I have my way, every linguistics major program will have a required 'origins' component.  I'll write the texbook myself, I will!

But until that can happen (and someone will probably beat me to it), for the budding evolutionary linguist, here are the seminal works to lay a foundation for getting a grasp of the discipline.  This is the best I can do to spread the evo-lingo love:


Pinker, S., and Bloom, P., 1990. Natural language and natural selection. Behavioral and Brain Sciences 13, 707-784.

This paper is commonly cited as starting the snowballing of interest in language evolution.  It was very important for the discipline to be seen as a legitimate line of study as well as for language to be viewed as a complex biological adaptation that had to have evolved.

Hauser, M. D., Chomsky, N., and Fitch, W. T., 2002. The faculty of language: what is it, who has it, and how did it evolve? Science 298, 1569-1579.

Probably the most widely read paper on evolutionary linguistics because of both the prominence of the authors and the unlikeliness of their co-authoring together.  The paper rocks up with an authoritative air, but kicks off a lot of argument and discussion, namely the resulting papers published by Pinker and Jackendoff in Cognition in 1995.  It was answered by HCF, and another reply by Pinker and Jackendoff was also published, all in Cognition between 2005 and 2007.

Jackendoff, R., 2002. Foundations of Language.

Ray Jackendoff outlines most clearly and for perhaps the first time, a reasonable complete picture of the way in which language likely arose. 

Christiansen, M., and Kirby, S.,2003. The Evolution of Language.
 
This book is an edited collection of essays from the leading evolutionary linguists in the field, speaking about a wide range of topics in the discipline from mirror neurons to the archaeological record to computerised simulations.

Johansson, S., 2005. Origins of Language: constraints on hypotheses.

Constraints are so important for focussing a new and excitable dsicipline like language evolution, and Sverker Johansson's book is a wonderful introduction to the discipline.


Bickerton, D., 2007b. Language evolution: a brief guide for linguists. Lingua 117, 510-526.

Derek Bickerton has been a major name in evolutionary linguistics for ages.  This paper outlines the discipline and provides a real focus on the questions it should be addressing.

Kenneally, C., 2008.  The First Word: The search for the origins of language.

Because the actual discipline of evolutionary linguistics is just as fascinating as the subject it studies, this is possibly my faovurite book on evolutionary lingusitics.

Botha, R., and Knight, C., 2009 (eds.). The Prehistory of Language.
Botha, R., and Knight, C., 2009 (eds.). The Cradle of Language.

These two books are collections of essays that, like Christiansen and Kirby's 2003 book, show a wide range of topics from a wide range of experts in the field giving is a good look at the state of the discipline.

If you manage to read all of these, email me and I will create a badge for you that says 'expert language origins master' or something :)

The 27th Northwest Linguistics Conference, Victoria Canada


UVic Campus

For almost 30 years, 4 universities in the Pacific Northwest of Canada (University of Washington, University of British Columbia, Simon Fraser University and University of Victoria) have alternated hosting the Northwest Linguistics Conference, a student lead conference for students in all areas of linguistics.  This year it is UVic’s turn to host the conference at their beautiful Vancouver Island campus full of their renowned campus bunnies.

I’m not a student… formally… but I was thinking it was worth a shot to submit an abstract (they confirmed that it is fine as long as I am not faculty!).  If it is accepted, it just gives me a fun extra reason to go back and visit family on The Island.  I have also only been to Victoria a handful of times, and it really is a beautiful place.


UVic bunny

In an earlier post, I discussed my ideas about the emergence of grammatical categories in human language and how there could not be a ‘first’ category because it would need to exist in contrast to another.  I was thinking this would be a comfortable topic to share for a 20 minute presentation, instead of discussing my Masters thesis topic, which I really think needs more work.

One of the benefits of presenting at the student conference, other than the obvious fun and networking, is that presenters get to submit their full paper to a Proceedings.  It would be a nice add to a very bare academic CV, and I’m always looking for opportunities to build.  Looking for, but not always fulfilling…

Mary Stiner Lecture: Cave Bears and Neanderthals

Mary Stiner and Steven Kuhn, both from the University of Arizona, are visiting professors at the UCL Institute of Archaeology through UCL's Leverhulme visiting professor scheme, and they are conducting a series of lectures about their research on Palaeolithic Archaeology over the next few months. 

On a Monday evening, Mary gave her second talk on Cave Bears and Neanderthals.  Her first, on cooperative hunting and meat sharing in the late lower palaeolithic, I had to miss due to work- but I was luckily able to make the second one (I also missed Steven Kuhn's first lecture, on ornamentation as information technology, but I try not to think about it as I really wanted to see that one!).  I will try my best to attend more of the public lectures Mary Stiner and Steven Kuhn and report on them here, when I can get away from my desk.

Mary introduced her topic with how cave bears are often depicted in conflict with prehistoric humans, as they were both users of caves.  She said there was a grain of truth in this, as they overlap both in time and space in Europe.

The cave bear was the largest bear of all time- even slightly bigger than the Kodiak bear, although even more robust.  The Kodiak bear, however, has a different morphology and habits.  It can climb trees when young, and is built for strength not speed.  The cave bear, which was probably much more slow and lumbering, with an absolutely massive cranium, lived on a seasonal veggie diet, and therefore hibernated in the winter.

Mary discussed the proposed cave bear cult briefly.  The type site for this is at Drachenlock, in the Swiss Alps.  There a cave bear skull was found with a femur (?) stuck through the zygomatic arch.  It looks at first glance very indicative of some sort of symbolic placement.  This and other sites, Mary said, have been increasingly embellished over time.

It makes sense to consider the odd placement of cave bear bones as being related to human ritual- bears are revered ethnographically by pretty much every human group that lives near them (I immediately thought of Native groups of the Pacific Northwest where I am from, as well as the Ainu of Japan who have a really interesting bear festival called Iomante- and for anyone who has read or seen the movie Clan of the Cave Bear, it will seem quite familiar!).  Associations between humans and bears in the archaeological record have been located in three circumstances in the archaeological record:
  • Cave art (ex. Chauvet cave- note, these paintings are made after Neanderthal occupation of Europe)
  • Bear remains in human middens (someitmes cutmarked or burned)
  • Bone accumulations (of mostly bear bones) with stone tools also present
Mary then went on to discuss in more detail a site in Yaraimburgaz Cave, Turkey.  It is a large cave abundant with cave bear bones in stratigraphic association with stone artefacts.  One part of the cave had actually been used as a Byzantine church.

The layers were dated by ESR (Electronic Spin Resonance) to 211-226 ka BP, which was during a cold interval within MIS 7.

The bones were scattered, some broken and some whole.  Most of the bones were not articulated other than the odd paw.  93% of the bones belonged to one type of cave bear.  There was also a very diverse range of other species present, and there was no burning and few (possibly 2) cut marks, if any, on the bones (not cave bear bones).

The lithics associated with it were not Mousterian, and were primative looking.  There were 1674 in all, of which 602 had been retouched.

Mary's question was, then, "why do the bear bones and the artefacts co-occur"?  She considered that:
  • Bears are sensitive about their locations when they hibernate, and keep food debris away rom the cave as it betrays their location to predators (also, interestingly, when a bear is hibernating it becomes odourless because its metabolism drops so low and it manages to reuse its own waste)
  • The mortality rate is high near the end of hibernation because of starvation
  • Skeletons are often moved around by other bears, and they can acumulate along with the slow sedimentation of the cave.
Mary looked at the mortality pattern in the cave.  Many bears were juveniles and old age adults, while prime age skeletons were comparatively rare.  There was also a relatively complete body part representation (although it was scattered). 

There was extensive gnawing on the bones, especially toe bones, which alludes to low traffic in the cave over a very long period of time.  There was a lot of gnawing from wolves, and wolf scat.

Mary also  looked at the % of bones gnawed with the % where marrow was accessed in a Pearson correlation matrix which I will not be able to comment on!  But there were some lovely charts and the interpretation that the lithics showed little relationship to the other remains.

Her final interpretation was that the cave represents a "palimsest of disparate events".  Bears used the cave for hibernation, and there was heavy use over generations with long quiet intervals in between.  Hominids and other carnivores only visited the cave briefly.

Because of the high proportion of retouched tools (which implies high mobility), few tool marks on the bones, no evidence of fire, no carcass processing, she interpreted that people were stopping at the cave, but not staying.

Next week (15 November) Mary will be speaking on the division of labour and diet diversification in the Mediterranean Palaeolithic.  I'll try my best to catch it!

Neanderthals in the News

Something that really irks me is the way that Neanderthals are potrayed in the popular media, even in science based outlets. Sensational titles like,
  • "Neanderthal Males had Popeye-like Arms" (Discovery News)
  • "Neanderthals Were More Promiscuous Than Modern Humans, Fossil Finger Bones Suggest" (ScienceDaily)
  • "Neanderthal man 'sang and danced'" (BBC)
  • Or, even, "Was Neanderthal man the original metrosexual? New study suggests he wore make-up" (to be fair, that last one was from the online version of the Daily Mail, Mail Online so we can't expect much!)
These titles suggest a whole lot more than the content the article actually discusses, much less findings of the research the article is written about.

It's true titles like these serve their purpose and grab the readers attention, and of course misleading titles altered to be more suprising or shocking pervades media on other topics too. But the result is that the message the reader takes away can be a very mislead one.

Yesterday an article on Neanderthals was published in ScienceNOW called "Neandertal Brains Developed More Like Chimps'". To the reader, this would have a very suggestive implication that Neanderthals brains are somehow chimp-like, and attrubute them with chimp-like behaviour. But really, what the article is about (http://news.sciencemag.org/sciencenow/2010/11/neandertal-brains-developed-more.html?rss=1), is how human brains are different from other primates, with a unique brain growth pattern early on in child brain development. Science Daily covered the same story with the title, "Brains of Neanderthals and Modern Humans Developed Differently", and Discovery News with, "Human, Neanderthal Brains the Same Until Birth".

It is facinating to look to our past in amusement when the first Neanderthal bones were uncovered in Germany in the 1850s, and how the image of the arthritic lumbering cave man emerged in popular culture. With todays media, however, that image looks no nearer to a true picture of our late sister species.

Uncharted Territory: where do we learn these things?

How does one become an academic?  How does one learn how to become one?

I don't imagine I am that alone, but I feel a bit like I'm bumbling along blindly in incipient academia- trying to write, network, and research my way into my choice career (albeit with a break to make money along the way).  I work in higher education, read the Times Higher religiously, and have a good grip on how universities function in some respects, so I feel like I should know more about the steps I need to take to succeed in one myself as a researcher and lecturer.  But I have no idea even how to apply for PhD funding, where to look, when or how to fill out university applications, and what order to do it all in.  And all as an overseas student, which throws the problems of Visas and funding eligibility into the mix.  Then there is the great beyond- do I apply for postdoctorates after I finish my course?  How long should I expect before I can get a post lecturing at a university?  Am I likely to have lecturing opportunities while I do my PhD?

It all resembles the mysticism surrounding the process when I started my MSc- it seemed I didn't know what I was doing until I was doing it.  Somehow it all fell together- finding the right course, personal statements, Visas, letters of recommendation, renting a flat, navigating London, attending/auditing courses and tackling the reading, and figuring out what a dissertation actually was while writing it at the same time.  It was as daunting as it was rewarding, and I expected it to be like that, but all the while I remember wishing I knew more about the next step, so I could be more prepared and set my ambitions high, but realistic.

The questions I have are, for instance: what steps are involved in a paper being published?  I've read around on a few journal sites, but still feel confused.  How much original research is needed for it to be a useful contribution to the discipline?

Should I publish my thesis?  If so, what do I need to do to modify it so it is ready for publishing?  I have this answer partly answered, and was making the appropriate changes, but with a full time job I am finding it hard to make time...

What else is there that I can do to strengthen my academic CV at this stage of my (not yet born) career?

What is my affiliation now to my university?  I work there administratively but I don't research there.  If I submit a paper, do I say I am from UCL?

These are the questions I have that I want to ask- but there are so many more I would want to ask, if I knew more about what it is I want to know!  The biggest problem I see is that it is all just unknown, and therefore, I don't even know what it is I don't know.
