Final answer:
Leslie White argued that the driving force of cultural evolution was technology.
Step-by-step explanation:
Leslie White argued that the driving force of cultural evolution was technology. He believed that new and better ways of making things resulted in new patterns of social practice and thought, leading to advanced civilization. White's viewpoint was influenced by previous theories of unilinear cultural evolution, which proposed that societies progress linearly through stages of savagery, barbarism, and civilization. However, it is important to note that this theory has been largely abandoned, as modern anthropologists recognize that cultures change according to their own unique historical trajectories.
