Final answer:
Dendrochronology is NOT an important aspect of fieldwork in Cultural Anthropology as it pertains to environmental studies and does not align with the qualitative methods like ethnography, observation, and rapport-building used in this field.
Step-by-step explanation:
To answer the question of which is NOT an important aspect of doing fieldwork in Cultural Anthropology, it's essential to understand the core practices involved in this discipline. For instance, ethnography is a fundamental aspect of cultural anthropology that involves the immersive study of people and cultures from within their socio-cultural contexts. Ethnography, therefore, heavily relies on observation and building rapport with the community being studied to gain deep insights. On the other hand, dendrochronology is the scientific method of dating tree rings to the exact year they were formed and is typically used in the context of environmental studies, archaeology, and physical geography, rather than in cultural anthropology's fieldwork. Hence, dendrochronology is not an important aspect of fieldwork for cultural anthropologists.
Cultural Anthropology fieldwork's pivotal elements include understanding cultural practices, social roles, and relationships. It is less about hypothesis testing or establishing causality, as is often the goal in other scientific fields, and more about the correlation of behaviors and cultural patterns, utilizing qualitative methodologies such as participant observation.
