Archaeology offers insights into climate change strategies

Once again, humanity might be well served to take heed from a history lesson. When the climate changed, when crops failed and famine threatened, the peoples of ancient Asia responded. They moved. They started growing different crops. They created new trade networks and innovated their way to solutions in other ways too.

So suggests new research by former WSU anthropologist Jade d’Alpoim Guedes and Kyle Bocinsky, an alumnus (PhD ’14) and adjunct faculty member in the Department of Anthropology, a senior researcher with the Village Ecodynamics Project, and the William D. Lipe Chair in Research with the Crow Canyon Archaeological Center in Cortez, Colorado.

Their paper, published in the journal Science Advances, describes a computer model they developed that shows for the first time when and where in Asia staple crops would have thrived or fared poorly between 5,000 and 1,000 years ago.

When the climate cooled, people moved away or turned to pastoralism—herds can thrive in grassland where food grains can’t. And they turned to trade. These strategies eventually coalesced into the development of the Silk Road, d’Alpoim Guedes and Bocinsky argue. In some areas they also diversified the types of crops they planted.

With their new computer model, the researchers were able to examine in detail how changing climate transformed people’s ability to produce food in particular places, and that enabled them to get at the causes of cultural shift.

Molecular analysis turns up an unexpected twist in smoking habits of ancient tribes

Tobacco plays a big role in Native American history and culture, predating Christopher Columbus’ arrival by well more than a millennium. But what did ancient tribes smoke? And can history help modern-day tribes put tobacco in its proper place?

A newly published study by Washington State University researchers traces the smoking habits of indigenous peoples in southeastern Washington state over the course of centuries, based on a molecular analysis of residue extracted from smoking pipes found at archaeological sites.

“This is the longest continuous biomolecular record of ancient tobacco smoking from a single region anywhere in the world—initially during an era of pithouse development, through the late pre-contact equestrian era, and into the historic period,” the research team, led by WSU anthropologist Shannon Tushingham, reports in the Proceedings of the National Academy of Sciences.

Back when Columbus got his first taste of tobacco, Native Americans viewed smoking as a ceremonial and religious ritual, marking occasions that ranged from prayers to peace treaties.

Today’s dominant strain of commercial tobacco, known by the scientific name Nicotiana tabacum, was introduced to tribes in the western United States by European settlers in the 1800s. Before contact, Western tribes ranging from Alaska to California used instead wild strains of tobacco, such as N. quadrivalvis (Indian tobacco) and N. attenuata (coyote tobacco).

Some tribes also were known to smoke an entirely different kind of plant called kinnikinnick or bearberry (which is now a popular ornamental plant for Northwest gardens).

Vancouver junior, Cowlitz Tribe member awarded National Udall Scholarship

WSU Vancouver cultural anthropology major Emma R. Johnson has received a prestigious and nationally competitive Udall Undergraduate Scholarship in its tribal public policy category.

“The Udall (Scholarship) is incredibly important to me,” said Johnson. “Completing all the work to apply and then being successful, it’s a really huge deal. It is helping me complete my education.”

Johnson is WSU’s fifth Udall recipient since 2015. The Udall Foundation, a federal agency, works both to strengthen the appreciation and stewardship of the environment, public lands and natural resources, and to strengthen Native Nations to facilitate their self-determination, governance and human capital goals.

The scholarship funds Johnson’s college tuition and fees for 2018-19, moving her closer to her career goal of serving the Cowlitz Indian Tribe, of which she is an enrolled member.

“My culture degree will come into play a lot in my future career working with both cultural and natural resources,” she said.

The Maya Kept Jaguar Zoos for Centuries

Erin Thornton.“It’s absolutely solid work,” says Erin Thornton, an anthropologist at Washington State University who specializes in isotope analysis.

“With animal remains from Mesoamerica, it’s very hard to tell if you’re dealing with a captive animal from bones alone,” she said. “Stable isotopes are really the only way to tell if an animal was removed from the wild and put under human management.”

Science on Tap: WSUV professor to share Ebola experiences

The first social scientist to be invited by the World Health Organization to help Ebola control efforts works right here in Clark County.

Barry Hewlett, an anthropology professor at Washington State University Vancouver, visited Central Africa to help the WHO in 2000, and he has visited the continent about five times as part of response efforts.

Hewlett will share stories on his experience, and how he worked to develop trust between local communities and the international and national response teams, at 7 p.m. Wednesday for Science on Tap at Kiggins Theatre in Vancouver.

When Hewlett first arrived, there was some apprehension from locals when it came to dealing with those response teams.

“The number of cases was going up, even though they were doing everything they thought they needed to do,” Hewlett said. “People were essentially running away from the World Health Organization treatment centers, isolation units and the rest. So the thought is, ‘What’s going on here?’ ”
