[LINK] "Greenland's viking settlers gorged on seals"

Via Will Baird at The Dragon's Tales comes a report from a Danish-Canadian team suggesting that the Norse settlers of medieval Greenland actually had a much more diverse diet, drawing heavily on local seals, than previously assumed. This fleibility in dietary matters, greater than expected, hints at a less catastrophic end to Greenlandic Norse society than expected--no sudden breakage or collapse, instead a story of rudimentary adaptation to the environment coupled with a quiet enough decline.

"Our analysis shows that the Norse in Greenland ate lots of food from the sea, especially seals," says Jan Heinemeier, Institute of Physics and Astronomy, Aarhus University.

"Even though the Norse are traditionally thought of as farmers, they adapted quickly to the Arctic environment and the unique hunting opportunities. During the period they were in Greenland, the Norse ate gradually more seals. By the 14th century, seals made up between 50 and 80 per cent of their diet."

The Danish and Canadian researchers are studying the 80 Norse skeletons kept at the University of Copenhagen's Laboratory of Biological Anthropology in order to determine their dietary habits. From studying the ratio of the isotopes carbon-13 and carbon-15, the researchers determined that a large proportion of the Greenlandic Norse diet came from the sea, particularly from seals. Heinemeier measured the levels of carbon isotopes in the skeletons, Erle Nelson of Simon Fraser University, in Vancouver, Canada, analysed the isotopes, while Niels Lynnerup of the University of Copenhagen, examined the skeletons.

"Nothing suggests that the Norse disappeared as a result of a natural disaster. If anything they might have become bored with eating seals out on the edge of the world. The skeletal evidence shows signs that they slowly left Greenland. For example, young women are underrepresented in the graves in the period toward the end of the Norse settlement. This indicates that the young in particular were leaving Greenland, and when the numbers of fertile women drops, the population cannot support itself," Lynnerup explains.

The findings challenge the prevailing view of the Norse as farmers that would have stubbornly stuck to agriculture until they lost the battle with Greenland's environment. These new results shake-up the traditional view of the Norse as farmers and have given archaeologists reason to rethink those theories.

"The Norse thought of themselves as farmers that cultivated the land and kept animals. But the archaeological evidence shows that they kept fewer and fewer animals, such as goats and sheep. So the farming identity was actually more a mental self-image, held in place by an over-class that maintained power through agriculture and land ownership, than it was a reality for ordinary people that were hardly picky eaters," Jette Arneborg, archaeologist and curator at the National Museum of Denmark, says.
