(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.

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.

正如这届美国政府中一切与贸易有关的事项一样,韩美贸易协定(Korus)的未来也不可避免地引发了激烈辩论。本届政府内部强烈反对退出该协议的是特朗普安全团队,他们认为在一场地缘政治危机期间切断与重要盟友的贸易纽带很可能不是个好主意。美国企业也不支持退出。这两股力量都可能意味着美国政府至少在短期内不会发出任何威胁。但是话又说回来,首尔方面的政治局势也不稳定。韩国新政府是否可能行使自己退出协定的权利呢?
