Explanation:
Franz Boas and his students made significant contributions to the development of new theories about culture by challenging ethnocentrism and promoting cultural relativism. They emphasized the importance of understanding each culture within its own context without judgment.
Armchair anthropology involved studying cultures from a distance, relying on second-hand information, while participant-observer fieldwork required immersing oneself in the culture being studied. Bronislaw Malinowski revolutionized anthropological fieldwork by introducing participant-observation, living among the Trobriand Islanders to understand their culture firsthand.
Ethical issues in anthropological research can arise from issues such as informed consent, cultural sensitivity, protection of participants' identities, and the impact of the research on the studied communities.
