Museums are buildings where objects of historical, artistic, scientific, or cultural interest are displayed. The Smithsonian’s National Museum of the American Indian has one of the world’s largest collections of Native artifacts, including many two- and three-dimensional objects such as baskets, pottery, and preserved specimens representative of the lives of Native populations from all areas of the country. Figure 3.5 This basket, woven by Kucadikadi (Mono Lake Paiute) artist Lucy Telles, is an excellent example of the art of basket weaving. Telles, whose work was done in the early part of the twentieth century, is widely admired for her use of color and innovative designs.

Early human ancestors learned how to make sharp blades useful for processing meat. They shared their knowledge of toolmaking in groups, passing those skills down to younger generations. Objects that are made and used by humans in group contexts are called material culture. All of the tools developed by early hominins (blades, arrows, axes, etc.) are examples of material culture. All of the artifacts discovered by archaeologists (buildings, pottery, beads, etc.) are examples of material culture. The specialized knowledge and skills used for making material culture are called technology. Today, the word technology is often used to refer to electronic devices such as smartphones and computers. For anthropologists, both smartphones and obsidian blades are forms of material culture produced through specialized technologies. That is, technology refers to the knowledge and skills required to make blades, phones, and other objects of material culture. Material culture is not just found in museums, of course. Material culture is all around. All of the furniture, appliances, books, dishes, and pictures on the walls in a typical American home are elements of material culture, and they reveal a great deal about the whole way of life of a society. Consider the toothbrush. It would be possible for people to clean their teeth with a found object such as a twig or leaf, or even with a finger. Ancient peoples often used a special chew stick, a twig with a frayed end. The bristled toothbrush was invented in 15th-century China and spread across Europe and into the United States, where it began to be mass produced in the late 19th century. Drugstores now feature many styles of toothbrush with an array of special features. Specialized teams design, manufacture, and market this wide variety of toothbrushes to consumers. Parents buy toothbrushes for their children and teach them the conventional techniques for brushing their teeth (little circles, two minutes, etc.). As adults, people often isolate themselves in a special room to brush their teeth in privacy. Even so, toothbrushing is a profoundly social act, relying on shared knowledge and observance of social norms for hygiene and health. Trees, rocks, microbes, and planets are all material objects, but they are not material culture unless they are made and used by humans in group contexts. For instance, a tree growing in a natural forest is not an object of material culture. However, an apple tree can be material culture if it is planted by a farmer in an orchard designed to produce fruit for human consumption. A microbe can be material culture if it is manufactured to improve human digestion or genetically engineered to fight cancer. Figure 3.6 This rock is on display in the British Museum. While a rock is not in and of itself material culture, this rock, which carries special meaning for those who view it, is. (credit: Archaeomoonwalker/Wikimedia Commons, CC BY 3.0) On display in the Cleveland Museum of Natural History is a gray rock. This rock was simply found by humans and never shaped for any particular use. Sitting there in the museum, it has no specific purpose other than to serve as an object of popular contemplation. Though it is a fairly unremarkable lump of basalt, thousands of people stop to gaze at this rock, reading the sign that describes how it was obtained, marveling at its presence there in the museum. Why? What’s so interesting about a rock? This particular rock was collected by astronauts on the Apollo 12 mission to the moon. The rock serves as evidence of this magnificent feat of scientific engineering and a source of great pride to the culture that accomplished such a mission. We go to museums to view the items on display there, but clearly, the human activities surrounding those objects are what make them interesting to us. That is, culture is not just material objects—it’s also what we do and what we think.
