Evolution of Language and the Evolution of Syntax: Same Debate, Same Solution?

I have recently realised that only after submitting my Masters thesis have I really started to understand my main arguement (a bit late perhaps?).  The arguement was located in the paper, but perhaps not clearly enough, probably because I wasn't thinking about it enough myself at the time.  I'll try to explain:

One of the debates that exist in language evolution research is whether language evolved abruptly, or gradually in many steps.  It is one of the topics of research I am most fascinated with, and was the subject of study for my MSc dissertation (you can read it here).

Abruptist arguments follow that language evolved in a mutation (suggested in writings by Gould and Lewontin, Piatelli-Palmerini, Crow, Klein, Hornstein, Lanyon, and even Chomsky), and possibly argue language could not have evolved gradually as an intermediate stage between language and non-language could not have existed (such as in Berwick's writings).  Gradualist arguments, which most contemporary evolutionary linguists side with and I too find much more biologically likely, approach language as not a monolithic thing, but made up of many different components that evolved in several stages over time (such as in the writings of Pinker, Jackendoff, Burling, Hurford, Kirby, Aitcheson, Kinsella, Heine and Kuteva, Fitch, and Johansson to name a few).

In the gradualist explanations of language evolution however, you often see reconstructions where there is a single step from a protolanguage (essentially a syntax-less language) and complex grammar.  I view this step as containing the same problems the idea that language evolved abruptly.  Syntax too is not a monolithic thing, and takes more than one cognitive step.  Modern languages contain complex syntax that requires certain memory capacities, and I think certain types of grammatical relationships would take more than just the learning of one rule, such as "merge".

In my thesis, I went through a literature review of gradual and abruptist arguments for language evolution, and posited an intermediate stage of syntactic complexity where a language might have only one level of embedding in its grammar.  It's a shaky and underdeveloped example of an intermediate stage of language, and requires a lot of exploration; but my reason for positing it in the first place is that I think we need to think of the evolution of syntax the way many researchers are seeing the evolution of language as a whole, not as a monolithic thing that evolved in one fell swoop as a consequence of a genetic mutation, but as a series of steps in increasing complexity.

Derek Bickerton, one of my favourite authors of evolutionary linguistics material, has written a number of excellent books and papers on the subject.  But he also argues that language likely experienced a jump from a syntax-less protolanguage to a fully modern version of complex syntax seen in languages today.  To me that seems unintuitive.  Children learn syntax in steps, and non-human species seem to only be able to grasp simple syntax.  Does this not suggest that it's possible to have a stable stage of intermediate syntax?

So my arguement is not very well developed, and I have a terrible example of what an intermediate stage of syntax might look like in my thesis.  But the errors you will likely find in my suppositions is beside the point; I've come to realise now that what I'm really trying to say is that we are treating the gap between non-syntax and syntax the way we have historically treated non-language and language- as a great leap.  And I would really like to explore the idea that relationships between words could first have been simple, and then relationships grew in complexity over time.

Musings... ramblings... blogging? Discuss.

It has been a year since I finished my MSc.  In my perfect world, I would now be a brazen young academic, publishing, presenting, contributing and networking through a fully funded PhD.  But instead, my academic dreams have become stagnant, on hold while I direct my attentions to the bottom line, and work like a real person in a 9-5 to pay off my enormous student loan debts.

I like my job, in fact I love it, and it IS in higher education (an assistant in a university development office).  But in some sense I feel I'm letting my real goals sit on the back burner, while I watch and don't participate in the academic field I long to play a part in.

Hence this blog.  In an effort to create SOME platform for my thoughts on palaeoanthropology and evolutionary linguistics, I will use this as an outlet for my musings, a place to put my ramblings, and hopefully even an opportunity to get some feedback/critisism and inspiraton.

So stay tuned; hopefully I will muster some interesting writings on topics in anthropology, archaeology, philosophy and linguistics, and hopefully you will be engaged.  I welcome discussion and critisism, mockery or flattery.

Thank you for reading,
