Archaeology expands beyond traditional scope into other sciences


April 30, 2012

The popular perception of archaeology is a team of dusty individuals in wide-brimmed hats unearthing treasures from a pharaoh’s tomb or an ancient collection of Native American artifacts.

Archaeology is that, but it is also a social science that utilizes information from other disciplines to inform and enhance archaeological data and to provide input to other sciences. Michael Smith, ASU anthropology professor, explores the broadened scope of archaeology in the paper “Archaeology as a Social Science” published this week in Proceedings of the National Academy of Sciences. Gary M. Feinman of The Field Museum in Chicago, Robert D. Drennan of University of Pittsburgh, Timothy Earle of Northwestern University and Ian Morris of Stanford University are co-authors of the paper.  Michael Smith Download Full Image

“A lot of people’s perceptions are based on classical archaeology (such as the study of ancient Greece or Rome), or on the latest tomb discovered or the biggest palace,” says Smith, of ASU’s School of Human Evolution and Social Change. “Viewing archaeology as a social science advances how we interpret sites and how we do research.”

Archaeology has greatly advanced during recent years. The discipline has expanded beyond anthropology, which studies the societies and cultures of the world, to include data and perspectives from other social sciences such as sociology.

“Looking at sociology and disciplines such as political science gives us more to draw from,” Smith said.

And archaeologists are able to reach beyond the time of written records to provide data that can be utilized in other sciences. For example, data on patterns of inequality and social stratification among ancient peoples can be utilized by sociologists.

Archaeologists also offer evidence that at times contradicts commonly held views of societies, for example, that of political scientists who may believe that life is chaotic outside of a state system with rulers and laws.  This belief doesn’t hold up when one examines the lives of Native American societies such as the Hohokam that lived peacefully in tribal settlements, Smith says.

Archaeology provides a full range of the human experience, including societies that are unlike any that exist in modern times. It provides records from all levels of society, including peasants and slaves, who often are left out of historical accounts, the archaeologists write in the paper.

Archaeological findings also provide a long-term perspective on change, documenting the origins of agriculture, the Urban Revolution, and other transformational social changes. Indeed, archaeology is crucial to a renewed interest in what is now called “Deep History.”

Practices that may be thought of as new phenomena may be traced through archaeological data. Urban farming is often thought of as an emerging trend in cities, but it was practiced by the ancient Mayan people 2,000 years ago.

“The whole notion of farming within cities is a pattern that has a lot of history,” Smith says.

Likewise, urban neighborhoods can universally be traced back thousands of years, indicating that neighborhoods are crucial in the ways that cities work.

“We look at the past and see lessons for the future,” he says.

This theme is the basis for a series of research projects within the School of Human Evolution and Social Change called “Late Lessons from Early History.” Funded by the Intellectual Fusion Investment Fund at ASU, these projects are built around cutting-edge transdisciplinary research in anthropology. Smith is working on a project that is focused on urban neighborhoods in ancient and modern cities.

While items like broken pieces of pots and stone tools might not seem ideal for analyzing past social systems, economic processes or political dynamics,  “analytical advances, including increasingly sophisticated applications of methods from chemistry and physics, now permit many past economic phenomena to be reconstructed with considerable detail,” the social scientists write.

Among additional recent advances in the science are the ability to pinpoint the places of origin of many raw materials and objects, reconstructing ancient technology and manufacturing, and new computing power that allow archaeologists to find and compare patterns in small finds from sites, the social scientists write.

Archaeologists increasingly are utilizing techniques such as radiocarbon dating of charcoal and a variety of instrumental methods from physics, chemistry and biology to contribute to their studies. Smith’s archaeological studies in Central Mexico take into account obsidian, used to make tools, that occurs naturally in 20 places throughout the region. Each obsidian source contains different trace elements.

“We can trace exactly where the rocks came from,” Smith said.

Archaeological data from many regions are now available, allowing comparative analyses of changes and social patterns. Furthermore, archaeology can contribute a new perspective because many of the societies they reconstruct are independent of the western cultural tradition that has been the focus of analysis by most of the social sciences.

Baseball takes two out of three in WSU series


April 30, 2012

The 23rd-ranked Arizona State baseball team rallied to tie the game in the top of the ninth inning, but Washington State hit a walk-off single in the bottom of the frame to win the series finale, 7-6, on Sunday at Bailey-Brayton Field in Pullman, Wash.

Abe Ruiz led off the ninth inning with a solo home run to bring the Sun Devils (26-17, 11-10) within one, 6-5. Kasey Coffman then singled with two outs and stole second before Nathaniel Causey came through with a pinch-hit, two-out RBI single to tie the game at six runs apiece. Download Full Image

Taylor Ard hit a two-out walk-off single off right-hander Jake Barrett (1-4) in the bottom of the ninth to give the Cougars (22-18, 8-9) a one-run victory. Barrett took the loss after allowing one run on a pair of hits in 1 1/3 innings.

The Cougars scored four runs on five hits in the first inning to take their first lead of the series, 4-0. ASU starting right-hander Darin Gillies was replaced with two outs in the frame by left-hander Matt Dunbar, who induced a groundout to end the inning.

ASU responded with two runs in the top of the third inning on an RBI groundout by Joey DeMichele and an RBI single by Ruiz. Trever Allen singled for the Devils' first base hit of the game, Andrew Aplin walked and a fielding error by the Cougars' third baseman on a Deven Marrero grounder loaded the bases with one out.

Adam Nelubowich and Ard hit a solo home run in the bottom of the third and fifth innings, respectively, to extend Washington State's lead, 6-2.

Aplin led off the seventh inning with a double to right field and Marrero followed with an RBI single as the Sun Devils cut their deficit to two, 6-4. DeMichele added a single in the next at-bat and James McDonald secured an RBI groundout two batters later.

The Devils loaded the bases in the eighth inning on two walks and a single, but a ground out by DeMichele with two outs kept ASU off the board.

WSU right-hander Anthony Drobnick (3-2) earned the win despite giving up two runs on three hits in the ninth inning. Starting left-hander Joe Pistorese allowed three runs, including one earned, on seven hits in six innings.

Dunbar gave up one run on four hits and struck out two in 3 1/3 innings before right-hander Joseph Lopez took the mound in the fifth frame. Lopez recorded six consecutive outs after giving up a home run to the first batter he faced.

The Sun Devils return to Packard Stadium to host Utah for a three-game Pac-12 series May 4-6. All three games will be broadcast live by Sun Devil Sports Network on The Fan AM 1060 and will also be webcast by FoxSportsArizona.com. The games on May 4 and May 5 are slated for a 6:30 p.m. start, while the contest on May 6 will begin at 12:30 p.m.

Game notes: Attendance was 525...right-hander Robert Ravago gave up two hits in 1 1/3 scoreless innings of relief...game time was 3 hours, 3 minutes.
