UC Davis researchers uncover earliest tobacco use in the Pacific Northwest

(Phys.org)—Native American hunter-gatherers living more than a thousand years ago in what is now northwestern California ate salmon, acorns and other foods, and now we know they also smoked tobacco—the earliest known usage in the Pacific Northwest, according to a new University of California, Davis, study.

"The study demonstrates that was part of the northwestern California culture very early ... shortly after the earliest documented Pacific Northwest Coast plank house villages," said the study, published in the .

Testing organic residues extracted from pipes, researchers from the UC Davis Department of Anthropology and the Fiehn Metabolomics Laboratory of the UC Davis Genome Center confirmed was smoked, and likely grown in the region, by at least A.D. 860.

Perhaps more importantly, the researchers say that additional studies may help them better understand the origins of and the human management, geographic range extension and cultivation of tobacco. Indeed, as part of a second study, the authors have recently detected nicotine in ancient pipes from an 800-year-old site in the modern city of Pleasanton, Calif.

The price of U.S. benchmark West Texas Intermediate crude, which is traded on the New York Mercantile Exchange, has been kept lower by problems transporting the oil to markets. Those troubles have eased recently, but Sabine Schels, head of fundamental commodity research at Bank of America Merrill Lynch, doubts the problems will disappear.

Prior to this recent testing, which used sensitive gas chromatography/mass spectrometry, researchers were unsure of the historical use of tobacco on the Coast. It was unclear, for example, whether European traders had brought tobacco to the area much later, or if some other plant had been smoked in the pipes, Tushingham said.

近几十年来,很少有年份像2014年那样一开始就充满那么多的悲观情绪。对2014年的预测贯穿了一个主题,即这一年看起来与1914年相似得让人害怕。大多数学者的预测都是悲观和令人沮丧的,尤其是对于东亚。然而,虽然发生了许多可怕的事件——从马航MH17航班在乌克兰坠落,到尼日利亚数百女学生被绑架,以及“伊拉克和黎凡特伊斯兰国”(Isis)的崛起——但我们避免了全面的世界大战。现在,2014年已结束,没有重现1914年的悲剧。探究为什么这些学者预测错了(特别是他们认为亚洲存在冲突可能性的想法)或许是明智的。

But many foresee an economic collapse, arguing that a prolonged eurozone crisis coupled with a property bubble could render vast swaths of Chinese industry unprofitable. This would reveal hidden financial vulnerabilities and feed a downward spiral. Others believe that Beijing has ample resources to avoid a crisis, but argue that, with a growth model based on infrastructure and land sales, and with exchange and interest rates rigidly controlled, it may not have all the necessary tools at its disposal.
