This general problem has led archaeologists (for example, London [2000]) to argue that anthropological work is not adequate for answering archaeological problems, and that archaeologists should therefore undertake ethnoarchaeological work to answer these problems. These studies have focused far more on the manufacture, use and discard of tools and other artifacts and have sought to answer such questions as what kinds of objects used in a living settlement are deposited in middens or other places where they may be preserved, and how likely an object is to be discarded near to the place where it was used.
