Scientific methods make archaeology interdisciplinary

Since the late 20th century, new theories and technologies have led to a series of significant developments in archaeology. Archaeobotanists have been tackling much broader questions about humans’ relationship to and use of their environment while at the same time determining much more precise facts. What changes have Chinese and Western archaeology gone through? What should scholars do in the fields of archaeobotany and public archaeology? CSST talked with Professor Gary W. Crawford about these issues.
CSST: The theoretical traditions of Chinese archaeology and Western archeology are completely different, with Western archaeology more closely aligned with anthropology while Chinese archeology has grown out of history. How does this affect archeologists’ output in China versus the West?
Crawford: We certainly have an overlap, because we both have history slightly in different way. Western archaeologists, especially North American archaeologists, still have to understand history. Understanding human society, culture, belief systems, choices people are making, and how they interact with their environment is important for us to find out what is happening. But this is just the beginning. So after that, we deal with other issues or problems. North American archaeologists spend a lot of time thinking about theories, models and explanations, and we have lots of discussions about theoretical models and new approaches to think about the past. Sometimes, we spend too little time discussing the facts. So there are many different theoretical perspectives coming from anthropological thinking and ecological thinking, and we try to use them more.
CSST: How did the New Archaeology Movement in the 1960s (also called “Processual Archeology”) influence the global development of archaeology?
Crawford: It is really the application of scientific methods to archaeology rather than historical methods. Archaeology became quite an interdisciplinary area that time. In some ways, it began to separate from anthropology too. In the late 1950s, there was the famous saying “American archaeology is anthropology or it is nothing.” It was a reaction against history, perhaps a little bit against science as well, but it was pushing people to think about things. Lots of debates began in the 1960s.
CSST: Besides new theories that emerged from this movement, how did new methods like technologies in the natural sciences and in archaeology itself change the discipline?
Crawford: In my field, there was a real push to recover the technical data from sites. In the 1960s, people were really thinking about origins of agriculture and how you can solve these problems. The University of Chicago, University of Michigan and other schools began to train people in methods, starting to feel the world is interdisciplinary. So instead of one archaeologist going to a site with a group of people and an excavator, they put a team together. One is for plant remains and one is for animals or soil. We even got people working on insects, or treating archaeological sites as a crime scene. We used every technique we could and schools began to train people in those fields. Partly what was going on was that in the 1950s and 1960s, there was a sense that science was going to solve all the world’s problems. So there was the really modern movement to popularize science. In North America, the Space Race to get to the moon first between Russia and the United States was really prominent. If you could use science to get to the moon, you could use science to do anything—cure cancer, and also solve archaeological problems. I was a science student, and I was really interested in science. In high school and as an undergraduate, I was encouraged to take science programs along with archaeology. There was a sense of getting new data and understanding the scientific side of things would cause revolutions in archaeology. And in fact, it did. And it still does.
One of the biggest developments in the 1950s was radiocarbon dating. Before radiocarbon dating, we were just guessing how old material was. When we finally were able to get facts—to get something dated—we were able to put better models about what is happening and how it’s happening. Then later on—I don’t know whether it was late 1960s or early 1970s—scientists figured out how to calibrate radiocarbon dating. That changed the impression even more. For example, in the Mediterranean, archaeologist thought all developments came out of Egypt. Development in Europe was supposed to be younger than Egypt. But it turned out that the development of Huge Stones and complex society were actually older than Egypt. That really surprised everybody. Calibrating radiocarbon dating was another revolution in archaeology because it changed the whole perspective of how things happened.
CSST: What have you been working on recently? What areas is your research covering and what kinds of achievements does your research gain?
Crawford: I think for me one of the biggest changes has been, what we can call “the Flotation Revolution” coming to China. I remember in the mid-1990s teaching two archaeologists how to do flotation in my kitchen in Canada. They were working on projects in China but no one was doing much flotation. I shipped one machine that we built in Toronto to China and when the data started to come out, there were so many remarkable results, especially very exciting results coming out of a couple projects related to the Longshan period (c. 3000-2000 BCE). We were amazed at the quality of data. To me, it was incredibly satisfying to see these wonderful results coming out. That’s one major development.
Being able to document the details behind plant use in the late Neolithic period of China and achieve the richness of a whole database is really unusual. But it leads to other questions. The data is so comprehensive. We know not just the crops, but also the weeds and other plants. We get a big picture for what’s going on and this is giving us an opportunity to look at how people are interacting with the environment. So my approach to all of these issues is what we call “anthropogenic interference” in English—the interaction of humans with the environment. How are people working with the environment? How does the environment change and impact people? So there are many big questions to ask. And China is an incredible laboratory in which to do that.
CSST: Archeology is undoubtedly something that has become more interesting and approachable for ordinary people over time. What do you think about public archaeology?
Crawford: Public archaeology acknowledges that knowledge gained from investigating the archaeological past has value to people beyond specialist archaeologists. There are plenty of different stakeholders. In other words, archaeology is relevant to our lives today and the relevance may be specific to different sectors of the public depending on their backgrounds and interests. For example archaeology has political relevance, and is relevant to tourism of course, land development, land entitlement and even relevant to who has access to museum collections and under what circumstances.
We might also consider a concept that we call “multiple narratives.” I know that sounds rather profound but it has a straightforward meaning. From the perspective of professional archaeologists in the West, a Chinese issue can help inform a broader problem such as urbanism or the origins of agriculture. The story or narrative that we tell about the Chinese situation has comparative relevance. For example, does urbanization start earlier or later in one area; do the same environmental circumstances apply; is urbanization linked to kinship-based groups or non-kin-based groups, or religious developments? The Chinese specialists may be concerned mainly with the local situation and they may not be particularly concerned about telling a story that links to international developments. Local people may be concerned about how to tell a story about a site that relates to or encourages local tourism and economic development. The facts may be the same but the emphases might be different. Each group may offer complementary insights or even different opinions. Public archaeology can involve a variety of voices of the different stakeholders.
