Final answer:
Lewis Henry Morgan developed an evolutionary model that placed technology at the center of cultural evolution, suggesting that advancements in technology lead to new social and intellectual patterns, evolving societies toward greater complexity.
Step-by-step explanation:
Lewis Henry Morgan's Evolutionary Model
American anthropologist Lewis Henry Morgan developed an evolutionary model that is recognized for its subdivision of human progress into more elaborate stages beyond what his predecessor, E.B. Tylor, had proposed. Focusing on technology as a pivotal force for cultural evolution, Morgan suggested that new and improved ways of manufacturing not only result in advanced tools but also bring about new societal patterns and intellectual constructs. Advanced technology, in his view, was synonymous with an advanced civilization. Morgan proposed a mechanism for the transitioning between these stages, assuming that every society evolves from simplicity to complexity through the specific mechanisms of development in technology, social structures, and thought processes. This concept was contrary to the belief in the static and unchangeable nature of the universe prior to the 19th century. His contributions, detailed in his work 'Systems of Consanguinity and Affinity of the Human Family' (1871), have been influential in the field of anthropology.
