In Anthropology and The Social Sciences
Diffusion studies explore the spread of ideas from culture to culture. Some anthropological theories hold that all cultures imitate ideas from one or a few original cultures, the Adam of the Bible or several cultural circles that overlap. Evolutionary diffusion theory holds that cultures are influenced by one another, but that similar ideas can be developed in isolation.
In mid-20th century, social scientists began to study how and why ideas spread from one person or culture to another. Everett Rogers pioneered diffusion of innovations studies, using research to prove factors in adoption and profiles of adopters of ideas. In 1976, in his book The Selfish Gene, Richard Dawkins suggested applying biological evolutionary theories to the spread of ideas. He coined the term meme to dibe an abstract unit of selection, equivalent to the gene in evolutionary biology.
