(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.

5. 地缘政治事件。不久之前,石油供应稍有差池,油价就会飙升。比如说2014年初,利比亚内乱造成该国石油出口中断,油价应声上涨。在伊拉克, 极端组织ISIS领了部分地区,石油供应中断的顾虑也造成油价急剧攀升。然而,自此之后,地缘政治事件对油价的影响大为减弱。2014年最后几周,利比亚再现战事。但市场仅在油价短暂上扬后便把这一问题抛诸脑后。不过,历史一再证明,地缘政治危机是对油价影响最大的短期因素之一。(财富中文网)

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.
