Iquito Fieldwork

June 21, 2008

I am back in Iquitos from the field for just a day. Tomorrow my partner Chris and I will be heading to the Iquito community of San Antonio de Pintuyacu for two weeks of intensive fieldwork, and to visit our friends in the community.

During these two weeks I have planned work on the Iquito ‘pitch accent’ system (really a mixed metrical/lexical tonal system), NP recursivity, discontinuous constituency in irrealis constructions, and some checking of the Iquito-Spanish dictionary that is nearing completion. 

In any event, I expect to be off  the air until around July 8th, as there is, alas, no internet connection in the community.

 

In search of Andoa

June 13, 2008

Tomorrow morning I travel from Lima to Iquitos, en route to the Río Pastaza. My reason for this brief trip is to follow up on information I have received that there are two elderly speakers of Andoa in the community of Andoas Viejo, which is located on the Río Pastaza, not far from the border with Ecuador.

Andoa is a member of the Zaparoan family of languages, which includes Iquito, a language with which I have worked a great deal over the last six years. In recent years I have become interested in the historical linguistics of the family, but there is something of a dearth of information on the other languages of the family. There is quite a good dictionary of Arabela, which includes an adequate description of the language’s morphology (Rich 1999), and a grammatical sketch of Záparo (Peeke 1991), but otherwise the data available on the other languages is very spare. In this context, even basic lexical and morphological data on Andoa would be a tremendous boon.

Andoa, however, is widely believed to be extinct — Ethnologue, for example, reports that that last speaker of Andoa died in 1993. However, in late 2006 I met an anthropologist in Iquitos who had recently made some recordings with two elderly Andoa speakers. I listened to them briefly, and my superficial impression was that the speakers displayed significant fluency. So, the report of the demise of Andoa may have been premature — and that is what I would like to ascertain on this trip.

(Incidentially, Nick Evans has a nice chapter entitled ” The last speaker is dead — long live the last speaker”, in Linguistic Fieldwork, edited by Paul Newman and Martha Ratliff, which discusses the phenomenon through which who counts as the “last speaker” of a language is frequently a moving target, as much tied to issues of local identity community politics as linguistic ability.)

On this particular trip I don’t anticipate doing a great deal of actual linguistic documentation. If I in fact locate any individuals who identify themselves as speakers, I hope to talk with them about a small-scale documentation project and see if they — and the community more generally — are interested. If I can, I would like to do enough work with the speakers to roughly gauge their level of fluency. Can they remember only core vocabulary, or can they easily construct relative clauses?

Interestingly, there are signs that the ethnically Andoa communities on the Ecuadorean side of the border have recently become interested in language documentation and revitalization. See, for example, a newspaper article here, and a UN report here. These reports indicate that there are several speakers on the Ecuadorean side, which leads me to hope that Ecuadorean linguists will be taking up the challenge to document the language on that side of the border.

A lively debate has been going on over at anthropology.net regarding a proposal by German Dziebel, expounded in his recent book, that modern humans originated in the Americas and spread from there to the rest of the world — an Out of America (OOAm) hypothesis to mirror the more widely-accepted Out of Africa (OOAf) hypothesis. The debate has been stimulated by two posts by Dziebel (here and here), which argue that many diverse sources of data suggest that modern humans originated in the Americas, or at the very least, the available data certainly do not rule this possibility out. Much of the debate in the comment threads focuses on genetic arguments, as one might expect, but I was interested in the linguist evidence. I asked Dziebel to elaborate on the linguistic evidence, and he kindly responded as follows:

Regarding the relevance of linguistic diversity in the Americas to the problem of the peopling of the Americas, I base myself off of Johanna Nichols’s “Linguistic diversity and the first settlement of the New World.” Language 66:3. (1990) as well as her Linguistic Diversity in Space and Time (1992).

Being stranded in Lima as I am, I have no access to Nichols’ 1992 book, but I was able get the Language article through JSTOR. In this post my goal is basically to evaluate to what degree the evidence and arguments presented in Nichols (1990), cited by Dziebel in support of the OOAm hypothesis, in fact support this hypothesis. For those who want the Reader’s Digest summary, my conclusions are the following: to a large degree, the basic evidence given in Nichols (1990) is neutral with respect to the OOAm hypothesis or competing hypotheses that place human origins in other continents. However, those parts of the paper that raise arguments relevant to distinguishing various origin hypotheses come down in favor of America as a site of colonization from the Old World, and not as a site from which humans migrated. (Just to be clear: I am not arguing for or against the OOAm hypothesis as a whole, but rather, taking on the much more restricted question of whether the linguistic evidence that Dziebel cites in fact supports the OOAm hypothesis.)

For Dziebel, the interesting point of Nichols (1990) lies in the relatively high linguistic diversity of the Americas and the implications of this diversity for the antiquity of human presence in the Americas. In his comment to me, Dziebel writes:

As measured by the number of independent linguistic stocks, linguistic divergence in the Americas must have taken at least 35,000 years. Of course, this figure cannot be taken literally but there’s a marked contrast between language diversity in the Americas (and in places like Papua New Guinea, with human archaeological record of some 40,000 years) and language diversity in Africa.

Dziebel raises two points here that are based on Nichols (1990). First, the linguistic diversity found in the Americas suggests that the human presence in the Americas goes back at least 35,000 years. And second, the human diversity of the Americas is significantly greater that found in Africa.

The arguments that Nichols (1990) marshals for the early date for the initiation of human migration to the Americas are very interesting, and rely on converging sources of data. However, the single most important piece of evidence is the sheer number of linguistic stocks found in the Americas. If we follow a uniformitarian assumption about rates of linguistic differentiation, and then calculate the rate of development of distinct stocks in other parts of the world, we are led to the conclusion that there is simply no way that the linguistic diversity we find in the Americas could have developed in the time window given by Clovis-based chronologies that posit that colonization of the Americas began around 12,000 years ago, or more recent accepted chronologies that push that date back to about 20,000 years ago. Pulling together as much linguistic and and archeological evidence as she can about migration rates across Beringia and the Bering Straits, Nichols suggests a date of roughly 35,000 years for the initial migrations into the Americas.

If we abstract away from the colonization-based scenario that Nichols employs, as Dziebel clearly does, we could argue that Nichols calculations support human presence in the Americas from 35,000 years ago — whether due to migration or otherwise. However, this interesting result cannot distinguish between the OOAm hypothesis and hypotheses that place human origins in other continents. It counts as an interesting piece of evidence regarding human presence in the Americas, but does not speak to the validity of OOAm, because it tells us nothing about how these humans got to be in the Americas.

It is worth noting that although Nichols (1990) does indeed argue for an earlier human presence in the Americas than do hypotheses based on physical remains, the entire point of the article is to develop a estimate for the date of human colonization of the Americas, based on linguistic evidence. Dziebel takes the early date for human presence in the Americas presented in the paper as support for the OOAm hypothesis, but discards the fact that this date is given in the context of a model for colonization of the Americas from the Old World.

Let us now take up Dziebel’s second point, which concerns the relative linguistic diversity of the Americas and Africa. Nichols (1990) observes that if one looks at the density of linguistic stocks globally, certain areas, such as New Guinea and South America, show a higher density that other areas, such as Europe. And, as Dziebel correctly notes, the density of the Americas as whole is higher than that of Africa. But, does this fact count as evidence either for or against OOAm? No, not at all.

Dziebel interest in the relative linguistic diversity of the Americas and of Africa lies in the supposed ability of linguistic diversity to predict the age of populations:

To summarize, linguistic diversity is a good and straightforward predictor of a population’s age if geography is factored in and if it’s checked against the mtDNA and Y-chromosome picture.

While it is certainly true that, all other things being equal, linguistic diversity in a region increases over time, it does not follow that linguistic diversity is a straightforward indicator of the age of that area’s population. The confounding factor is large-scale language shift. As Nichols argues, there is good reason to believe that in Europe, for example, Indo-European languages replaced pre-Indo-European languages on a massive scale, radically reducing the linguistic diversity of the region.

Of course, Dziebel also mentions the “mtDNA and Y-chromosome picture” — but it’s not clear to me how this is relevant to the utility of using linguistic diversity to estimate the age of a population, unless his following comment gives us a clue:

Linguistic diversity steadily increases with time, unless this process is checked by geography and reversed by population replacements.

So here it appears that Dziebel makes use of the concept of ‘population replacement’ to account for interruptions in the steady growth of linguist diverstiy. But of course, language shift need not co-occur with population replacement, entirely disrupting the tidy correspondence between linguistic diversity and the age of populations. In Europe, for example, Nichols argues that Indo-European *languages* replaced pre-Indo-European ones, not that *populations* were replaced. The result was a loss of linguistic diversity. And as the following comment shows, Dziebel seems perfectly aware of this fact:

Translated into the levels of linguistic diversity, Europe experienced periods of language replacement (now it’s dominated by Indo-European languages) but all these replacements originated from the same genetic pool.

But then he concludes:

However the factors of geography and population replacement are subordinate to the factor of spontaneous differentiation because differentiation occurs all the time and everywhere, while geographical constraints and population replacements are accidental events.

What Dziebel seems to be arguing here is that even though we know that language shift occurs — and on vast scales, as in Europe and Africa — at the end of the day, linguistic diversity is still a reliable measure of a population’s age. But this is clearly false — or maybe I am misunderstanding his point. The fact that large-scale language shift occurs, without necessarily significant changes in the *biological* population, means that linguistic diversity is good as a measure of the amount of time that has transpired *subsequent to* such large scale linguistic shifts. These shifts largely erase the linguistic history of an area, screening off the population’s age prior to that point from measures based on linguistic diversity.

The fact that such large scale shifts appear to have occurred in Africa and Europe means that measures of linguistic diversity simply cannot tell us very much about the ultimate ages of those populations. Consequently, the fact that the Americas display greater linguistic diversity than Africa tells us nothing about the relative ages of the populations of the two regions. The linguistic diversity evidence that Dziebel cites simply does not bear on the validity of OOAm.

Apart from the linguistic diversity evidence just discussed, Dziebel also cites typological evidence:

The distribution of grammatical features (such as head-marking vs. dependent-marking, numeral classifiers, etc.) again shows a cline from America and Australasia to Africa and Europe, and Nichols’s argued that our perspective on an early human language comes from America and Australasia and not Africa and Europe.

It is certainly true that Nichols (1990) observes certain typological features appear to cluster in certain geographical areas, and that intermediate areas show intermediate values for the parameters in question. Thus, as extremes, South America shows a very high proportion of head-marking languages, while Europe and Africa show a very high proportion of dependent-marking languages. Intermediate areas, such as Australasia, tend to show either mixed-marking or double-marking. However, the fact that one can identify typological parameters that exhibit a cline of values between the Americas, on the one hand, and Europe and Africa, on the other, tells us little about the locus of modern human origins. By themselves, these linguistic facts are consistent with both OOAm and OOAf scenarios. They simply do not speak to validity of one hypothesis over the other.

Dziebel also says, however, that “Nichols’s argued that our perspective on an early human language comes from America and Australasia and not Africa and Europe.” Well, if she does so in Nichols (1990), I can’t find it. The closest argument I can find in Nichols (1990) to the one that Dziebel attributes to her is an observation about the relationship between colonization and the preservation of linguistic features. To summarize, Nichols observes that when new areas are colonized, it is not unusual for linguistic features to survive in the colonized area that are subsequently lost in the areas from which the linguistic stocks originally spread. Note, of course, that the languages in the colonized area continue to change, as do all human languages, so it is misleading to characterize them as somehow reflecting “early human languages”. Rather, the languages in questions simply preserve some features that were present at the time of colonization, and which tend to get lost in the original area due to language shift. Note, btw, that *were* it possible to show that American languages retain certain features subsequently lost in other parts of the world, this would actually serve as evidence, following Nichols’ arguments, for the Americas having been colonized from the Old World, rather than the reverse, as Dziebel proposes.

Thus far, then, I can find no evidence in Nichols (1990) that supports the OOAm hypothesis. I now wish to briefly review evidence given in the paper that argues against the OOAm hypothesis.

First, linguistic diversity in the Americas tends to increase the further south one goes. Modulo issues of language shift, touched on above, this fact suggests that the older American populations are found in the south, and successively more recent populations are found in Meso-America and North America. These facts are easy to reconcile with a scenario in which populations entered the American in the north in stages, with subsequent populations pushing prior ones towards the south. It is not clear how these linguistic diversity facts fit with an OOAm scenario.

Second, Nichols argues that linguistic diversity is, in general, higher in areas that have been colonized than the centers from which colonization occurred (a point to which I alluded above). Nichols argues (p. 487) that this is due to the fact that centers are loci of large scale economies, which result in linguistic spreads that reduce linguistic diversity. The greater linguistic diversity of the Americas is, by this reasoning, supportive of the Americas being a colonized region, and not the OOAm hypothesis.

To summarize, Dziebel cited Nichols (1990) as a source of evidence and arguments that support the OOAm hypothesis. In particular, Dziebel cites linguistic evidence from this work for the antiquity of human settlement in the Americas and for the existence of a typological cline linking the Old World and New. However, neither piece of evidence supports an OOAm scenario over a OOAf scenario (or vice versa). However, other evidence and arguments presented in Nichols (1990) casts doubt on an OOAm scenario. In particular, the evidence regarding linguistic diversity within the Americas is consistent with a process of colonization of the New Word by multiple migrations from the north, but is not easy to reconcile with a an OOAm scenario. Additionally, Nichols makes arguments regarding the effects of colonization on linguistic diversity which are consistent with the Americas being the site of colonization, but not with the Americas being the point from which the Old World was colonized.

Regardless of the ultimate validity of the OOAm hypothesis, then, the linguistic arguments Dziebel presents in its favor are unconvincing to me. I wish to emphasize that I am restricting my attention to the linguistic arguments, and it is possible that the genetic arguments or those based on kinship terminology provide much better evidence for OOAm. At this point, however, I am led to conclude that the linguistic evidence that Dziebel has presented so far in favor of OOAm is weak.

Much to my surprise, I am still in Lima, still waiting to head off to the field. The logistical complications that have led to my prolonged stay in Lima have gotten me thinking about the concept of the ‘hollow frontier’ in Amazonia — for reasons that will become clear. The notion of the hollow frontier is an old one in Brazilian historiography, but I first came across it several years ago while reading William Fisher’s Rainforest Exchanges, a work on the interaction between extractive industry and community politics among the Xikrin Kayapo of central Brazil.

In this work, Fisher invokes the notion of the ‘hollow frontier’ as way of understanding important aspects of the history of Amazonia from the 18th century on. In particular, Fisher uses the concept to talk about the waves of extractive industry — among them the sarsparilla, rubber, and timber industries — that have swept through Amazonia. In North America, extractive industries frequently formed the leading edge of long-term colonization of areas previously inhabited and controlled by indigenous peoples. In much of Amazonia, in contrast, the successive waves of extractive activity have not served as the leading edge of substantial permanent settlement by non-indigenous peoples. Rather, as soon as the extractivist boom collapses, non-indigenous population in the extractive zones drops back off, as does the interest of the nation state, and most of the temporary infrastructure that supported the extractive industry evaporates. In Amazonia, then, the waves of extractive industry are not so much the leading edge of permanent non-indigenous colonization as short term extractivist booms that leave relatively little state influence or infrastructure in their wake.

My recent reflections on the hollow frontier have been triggered by the fact that my delay in Lima are in large part the consequence of the ongoing collapse of one of these hollow frontiers near one of my fieldsites, the town of Sepahua.

Sepahua is a small town on the banks of the lower Urubamba River, near the southern border of the departmento of Ucayali, that has for several decades effectively marked the edge of mestizo society in its area of the selva. The town began as a Dominican mission that was founded in 1948 to missionize the Amahuaca, Yine (Piro), and Asháninka living in the area, and a small mestizo settlement of traders and minor extractivists began to grow at the side of the mission not long after its foundation. At this time Sepahua was very difficult to get to from the main mestizo jungle urban centers like Pucallpa, requiring a river journey of roughly two weeks. One can get a sense of how remote mestizos and the Peruvian state considered Sepahua by the fact that Sepahua was a day’s travel beyond a penal colony founded in 1951 at the mouth of the Sepa River, a tributary of the Urubamba.

The town grew very slowly until the early 1980s, when rising prices for tropical hardwoods, especially mahogany, made logging in this remote region quite profitable. Another extractivist boom hit the region at about the same time: Shell began petrochemical exploration in the region. Shell built a significant airstrip in Sepahua and a variety of commercial businesses sprang up to supply the company and its workers — from bars and brothels to dry goods merchants. Shell left the region in the late 1980s, but many of the people drawn to Sepahua by Shell stayed and turned to logging to support themselves. Rising prices for mahogany and cedar drew even more people, and by the early 1990s, huge amounts of timber were being harvested from an ever-widening area around Sepahua.

The growth of Sepahua received some unusual help in 1991/2 when the town was attacked by a small group of Sendero Luminoso. The attack did little more than frighten the townsfolk, but the Fujimori government took no chances. To protect the airstrip and prevent the expansion of the SL into this new area, the government built a base and sent in a detachment of marines, which further stimulated commercial growth in Sepahua.

I first visited Sepahua in 1993, and even between then and the late 1990s, the town grew by leaps and bounds, reaching a population of about 4000. Sepahua was a real boom town. By the late 1990s, however, accessible timber was getting noticeably scarcer. The economic collapse of the region was fended off for a few more years by a modest amount of local economic activity linked to the Camisea natural gas project, but by the time this income dried up, logging in the region was in serious decline.

Airplane flights, which were weekly in the early 1990s and almost daily in the late 1990s and early 2000s, became monthly and then ceased altogether when the airstrip could no longer be maintained. Symptomatic of Sepahua’s decline, the military presence in the town was reduced to almost zero a few years ago. As of 2007, when I was last there, the only reliable way to get to Sepahua was by boat, a return to the early 1980s. But even here, things were no longer the same: the collapse of the hollow frontier in Sepahua meant that even river transport became relatively scarce.

Which bring us to me, sitting in Lima. If it were just a question of getting myself to Sepahua, there would not be much of an issue. The trip would be more circuitous and time-consuming than in years past, but I would be able to get from Lima to Sepahua in 4-5 days. The problem is that I also need to transport a sizable quantity of medical supplies to Sepahua, as part of an agreement with several indigenous communities in the region. And here the impact of the collapse of the hollow frontier in the Sepahua region is strongest: previously, there was a regular overland-and-river route from Lima to Sepahua run by numerous traders in Sepahua to supply manufactured goods to the town. However, with the collapse of logging in the Sepahua region, demand for goods has largely dried up, and now there is only one person doing the route — and very irregularly at that! The economic activity and infrastructure that I came to rely on over the course of the last decade has largely evaporated, a victim of the hollow frontier.

It has been close to two years since I was last in Sepahua, so it will be interesting to see how the town has fared. In the go-go early 2000s, Sepahua even had internet service, but when I was last there, it seemed to be on its last legs. If the internet connection is still working when I eventually get there, I will be sure to write a short post. The hollow frontier being what it is, though, I’m not counting on it.
