What is the origin of ethnology?

Context: Sociocultural anthropology/ethnology:
This field can trace its roots to processes of European colonization and globalization, when European trade with other parts of the world and eventual political control of overseas territories offered scholars access to different cultures. Anthropology was the scientific discipline that searches to understand human diversity, both culturally and biologically. Originally anthropology focused on understanding groups of people then considered "primitive" or "simple" whereas sociology focused on modern urban societies in Europe and North America although more recently cultural anthropology looks at all cultures around the world, including those in developed countries. Over the years, sociocultural anthropology has influenced other disciplines like urban studies, gender studies, ethnic studies and has developed a number of sub-disciplines like medical anthropology, political anthropology, environmental anthropology, applied anthropology, psychological anthropology, economic anthropology and others have developed.

Answer: Ethnology can trace its roots to European colonization and globalization.
