Which of the following is NOT a focus of cultural anthropology?

The focus of cultural anthropology primarily revolves around understanding the cultural aspects of human life, including systems of meaning, social structures, and the various expressions of culture such as beliefs, practices, and social relationships. Ethnography is a key method within cultural anthropology, where anthropologists immerse themselves in cultures to gather data and gain insights into people's lives. Cultural patterns and social relationships are fundamental components that cultural anthropologists study, as they illustrate how societies organize themselves and interact based on shared beliefs and practices.

Human evolution, however, is not a primary focus of cultural anthropology; it is more closely related to biological anthropology. This discipline explores the biological and evolutionary aspects of humans, including physical development and genetic variation over time, which distinguishes it from cultural anthropology's emphasis on societal customs, beliefs, and practices. Thus, the study of human evolution falls outside the primary concerns of cultural anthropology.
