Ethnology, a branch of anthropology, investigates the traits and connections among human groups through comparative cultural analysis. While ethnography concentrates on specific societies, ethnology integrates findings to uncover patterns, such as cultural universals like the incest taboo. Scholars such as Thomas Huxley examined environmental impacts on human development, whereas Jesse Walter Fewkes prioritized the study of racial and intellectual characteristics.
William Henry Flower described ethnology as encompassing the physical, social, and linguistic dimensions of human populations. E. W. Burgess emphasized common behavioral tendencies across varied cultures. By combining empirical observation with theoretical models, ethnology aims to balance external influences with internal human factors, exposing both commonalities and differences within humanity.
