Cultures change in a number of ways. The only way new cultural traits emerge is through the process of discovery and invention. Someone perceives a need and invents something to meet that need. Seems a simple enough concept; however, it often takes a long time for a new invention to be fully integrated into a culture. Why? Because often other elements of the culture have to change to meet or maintain the needs of the new invention. This is referred to as culture lag. The automobile is a good example of discovery and invention and culture lag. The auto was invented as a mode of more efficient transportation. Many things had to change in order for the automobile to become a fixture in a culture. People had to be persuaded that the automobile was a better form of transportation. Roads had to be constructed; a way to procure fuel needed to be developed; mechanics were needed to fix cars; efficient production of cars had to be developed to meet supply demands; safety concerns, rules of the road, insurance, and numerous other elements of culture had to catch up with the invention of the automobile.
Another way cultures change is through diffusion. Diffusion is simply the borrowing of traits. There is a long laundry list of things in US culture that were borrowed from other cultures. Pajamas made their way to the US from India. Spaghetti was borrowed from China by way of Italy, and corn came from Mesoamerica. Ralph Linton, a noted anthropologist, wrote a short article entitled “One Hundred Percent American” in which he outlines numerous things that U.S. culture borrowed from other cultures.

Yet another way cultures change is through the process of acculturation. Acculturation is also the borrowing of traits; however, there is a superordinate, or dominant, and subordinate, or minority, relationship between cultures. The dominant culture picks and chooses those traits from the subordinate culture that it deems useful, i.e., diffusion. The subordinate culture is pressured to adopt the traits of the dominant culture. It is the element of pressure that differentiates acculturation from diffusion.
Acculturation manifests itself in multiple ways. One way is called the Melting Pot. The melting pot refers to a blending of cultures. This primarily occurs through intermarriage of people from the two cultures. What frequently happens is that one of the two cultures is dominant and the other subordinate within the relationship so that only some of its traits are practiced.
Another form of acculturation is called the Salad Bowl, or cultural pluralism. This occurs when people immigrate and keep as many original cultural traits as possible. Chinatown in San Francisco is a good example of the salad bowl. The different types of acculturation are not necessarily mutually exclusive. Even in the case of cultural pluralism people must adopt certain traits of the host country; i.e., the laws, in order to thrive, but they do keep as many traditions as possible.
Host conformity occurs when an individual has fully assimilated into the host culture.
