Lost world

University of Birmingham researchers are heralding "stunning" findings as they map the "best-preserved prehistoric landscape in Europe".

This large plain disappeared below the water more than 8,000 years ago.

The Birmingham researchers have been using oil exploration technology to build a map of the once-inhabited area that now lies below the North Sea - stretching from the east coast of Britain up to the Shetland Islands and across to Scandinavia.

'Terrifying'

"It's like finding another country," says Professor Vince Gaffney, chair in Landscape Archaeology and Geomatics.

It also serves as a warning for the scale of impact that climate change can cause, he says.

Human communities would have lost their homelands as the rising water began to encroach upon the wide, low-lying plains.

"At times this change would have been insidious and slow - but at times, it could have been terrifyingly fast. It would have been very traumatic for these people," he says.

"It would be a mistake to think that these people were unsophisticated or without culture... they would have had names for the rivers and hills and spiritual associations - it would have been a catastrophic loss," says Professor Gaffney.

As the temperature rose and glaciers retreated and water levels rose, the inhabitants would have been pushed off their hunting grounds and forced towards higher land - including to what is now modern-day Britain.

"In 10,000 BC, hunter-gatherers were living on the land in the middle of the North Sea. By 6,000 BC, Britain was an island. The area we have mapped was wiped out in the space of 4,000 years," explains Professor Gaffney.

So far, the team has examined a 23,000-sq-km area of the sea bed - mapping out coastlines, rivers, hills, sandbanks and salt marshes as they would have appeared about 12,000 years ago.

And once the physical features have been established, Professor Gaffney says it will be possible to narrow the search for sites that could yield more evidence of how these prehistoric people lived.

These inhabitants would have lived in family groups in huts and hunted animals such as deer.

The mapping of this landscape could also raise questions about its preservation, says Professor Gaffney - and how it can be protected from activities such as pipe-laying and the building of wind farms.

Linguists doubt exception to universal grammar

Controversies in the field of linguistics seldom make headlines, which is why the current imbroglio over an alleged counterexample to Universal Grammar (UG), made famous in the 1960s by Noam Chomsky, MIT professor of linguistics, is so unusual.On one side is Daniel L. Everett, a linguist at Illinois State University, who has spent several decades studying Pirahã, a language spoken by roughly 350 indigenous hunter-gatherers in the Amazon rainforest. On the other are a number of linguists, including MIT linguistics professor David Pesetsky, who have thrown doubt upon many of Everett's claims, both cultural and linguistic, about the Pirahã.In a telephone interview, Pesetsky said, "What we tried to do in our response was to highlight the ways in which we are trying to unravel the system that unites all the languages in the world," including Pirahã. The attributes that Everett claims are unique to that language are in fact extant in other well-documented languages, such as Bengali and even German.Linguistics began to focus attention on UG several decades ago in an attempt to move their study from the particularization of philology--the detailed description of individual languages and language families, with which the field was preoccupied for centuries--to an understanding of the remarkable wealth of features that all languages share, and thence to an understanding of the human mind.
The current contretemps began with Everett's 2005 paper in Cultural Anthropology, "Cultural Constraints on Grammar and Cognition in Pirahã: Another Look at the Design Features of Human Language," which described a number of "gaps" in Pirahã morphosyntax (the relationships between words and how their elements convey meaning).
As a culture, says Everett, Pirahã speakers lack any sense of the past beyond what living individuals have personally experienced, and they have no creation myths or fiction, no sense of numbers or counting, and no art. Constraints of culture, Everett believes, in turn impoverish the language, which has no tenses, no names for colors and other allegedly unique paucities.
The language constraints, he claims, indicate "some of the components of so-called core grammar are subject to cultural constraints, something that is predicted not to occur" by Chomsky's universal-grammar model.
Everett's article and his colorful field career have been taken up by the popular press, with stories in the Independent, Der Spiegel and, most recently, the New Yorker, among other publications.
His critics--Pesetsky, Andrew Nevins of Harvard and Cilene Rodrigues of the Universidade Estadual de Campinas in Brazil--fired back in March of this year with a paper entitled "Pirahã Exceptionality: A Reassessment," taking issue with virtually every claim to Pirahã's uniqueness that Everett advanced. Everett hastily answered (also in March), with "Cultural Constraints on Grammar in Pirahã: A Reply to Nevins, Pesetsky, and Rodrigues (2007)." (Those two papers may be viewed at the LingBuzz linguistics archive site, ling.auf.net/lingbuzz, where they head the "Top Recent Downloads" list.)
Pesetsky marvels at the interest this debate has sparked, not only within the field but in the world at large. As of April 12, he noted in an e-mail, "Our paper has been downloaded 1,300 times and (Everett's) reply has been downloaded 910 times--astonishing figures for the site and for a field like linguistics."
While linguists at MIT pay a lot of attention to theoretical questions, such as the universal properties of sound systems, speech perception and speech production, field linguistics is far from moribund here. Linguistics grad student Seth Cable is heading off soon to Alaska on an National Science Foundation dissertation grant, to study the syntax and semantics of questions in Tlingit, a language spoken by an indigenous people of the Pacific Northwest. And one of the great figures in field linguistics, the late Kenneth Hale, was an esteemed member of the MIT faculty until his retirement in 1999; in his long career, he worked on languages as diverse as Hopi, Tohono O'odham (of the Sonoran desert region) and Warlpiri. His fluency in the latter, an indigenous language of Australia, was such that he was able to keep his sons, Ezra and Caleb, fluent in the language even after they had moved back to the United States. "He was a linguist's linguist," as Pesetsky put it.
