Theories
The many models that have been proposed for inter-cultural diffusion are
- Hyperdiffusionism —the theory that all cultures originated from one culture.
- Culture circles diffusionism (Kulturkreise)—the theory that cultures originated from a small number of cultures.
- Evolutionary diffusionism—the theory that societies are influenced by others and that all humans share psychological traits that make them equally likely to innovate, resulting in development of similar innovations in isolation.
- Mallory's "Kulturkugel" (a German compound meaning "culture bullet", coined by Mallory himself), a term suggested by J. P. Mallory to model the scale of invasion vs. gradual migration vs. diffusion. According to this model, local continuity of material culture and social organization is stronger than linguistic continuity, so that cultural contact or limited migration regularly leads to linguistic changes without affecting material culture or social organization.
A concept that has often been mentioned in this regard, which may be framed in the evolutionary diffusionism model, is that of "an idea whose time has come" — whereby a new cultural item appears almost simultaneously and independently in several widely separated places, after certain prerequisite items have diffused across the respective communities. This concept has been invoked, for example, with regard to the development of calculus by Newton and Leibnitz, or the inventions of the airplane and of the electronic computer.

Famous quotes containing the word theories:
“It takes twenty or so years before a mother can know with any certainty how effective her theories have been—and even then there are surprises. The daily newspapers raise the most frightening questions of all for a mother of sons: Could my once sweet babes ever become violent men? Are my sons really who I think they are?”
—Mary Kay Blakely (20th century)
“The real trouble about women is that they must always go on trying to adapt themselves to men’s theories of women, as they always have done. When a woman is thoroughly herself, she is being what her type of man wants her to be. When a woman is hysterical it’s because she doesn’t quite know what to be, which pattern to follow, which man’s picture of woman to live up to.”
—D.H. (David Herbert)
“Our books of science, as they improve in accuracy, are in danger of losing the freshness and vigor and readiness to appreciate the real laws of Nature, which is a marked merit in the ofttimes false theories of the ancients.”
—Henry David Thoreau (1817–1862)
