Final answer:
The specific anthropologist who studied labor practices among the !Kung bushmen wasn't provided, but the field of anthropology includes extensive fieldwork and various areas of study ranging from cultural and psychological aspects to political systems as demonstrated by historical figures like Malinowski, Benedict, Mead, Evans-Pritchard, and Fortes.
Step-by-step explanation:
The anthropologist who studied labor practices among the !Kung bushmen was not mentioned in the provided reference material. However, cultural anthropologists like John Marshall conducted fieldwork among the !Kung people, and his work resulted in films such as 'N/um Tchai: The Ceremonial Dance of the !Kung Bushmen.' Anthropology involves living within the community and adopting local practices to better understand the culture, a method employed by pioneers like Bronislaw Malinowski and his study on the Trobriand peoples. The field also includes psychological aspects, as seen in the work of anthropologists such as Ruth Benedict, Margaret Mead, and Edward Sapir, and even encompasses the examination of political systems, highlighted by E. E. Evans-Pritchard and Meyer Fortes in their work on African political systems.
