I want to know the answer to the following question:
What four fields make up American anthropology which play a vital role on its research of culture?
All the background I'm provided with is that "Although anthropologists worldwide refer to Tylor's definition of culture, in the 20th century "culture" emerged as the central and unifying concept of American anthropology, where it most commonly refers to the universal human capacity to classify and encode human experiences symbolically, and to communicate symbolically encoded experiences socially.[citation needed]". Is that enough to answer the question?
Answer: no
