What is one way this culture has been changed or affected by cultural diffusion?

Cultural diffusion has allowed different traditions or cultures to spread and merge with other traditions or cultures. This is what happened in the US. As more people come to the US the more the Western culture is changed and affected by other cultures and traditions. An example of this would be if there was an area where it was all Native Americans and they had their Native american culture. Now let's say a group just as big of Native Africans moved to the exact same area, over time, the two cultures would start to mix. The US has been strongly effected by cultural diffusion, and in history they referred to it as the melting pot of cultures.
