Answer: Cultural Evolutionism.
Cultural evolution is the theory that cultures change over time, similar to the evolution seen in biological organisms. It is based on the idea that cultures evolve and adapt to their environment and circumstances. An example is a transition from hunting-gathering society to an agricultural one based on the available land resources.
The view that cultures, like organisms, change over time is called cultural evolution. This theory posits that societal changes and developments happen gradually over time, analogously to the evolutionary changes seen in biological organisms. The concept of cultural evolution originates from 19th-century anthropology and was heavily influenced by Charles Darwin’s theory of natural selection. While there are debates and variations within this theory, at its base, it suggests that cultures evolve and adapt to their environment and circumstances, with these changes advantaging certain societies and helping them to succeed and prosper.
For instance, a culture that originally practiced hunting and gathering may evolve into an agricultural society when it encounters a fertile and productive land. This evolution of culture and society is not linear or inevitable, but dependent on a multitude of factors, including environmental, economic, and social conditions.
