Modern society is filled with references to the speed at which change happens—mainstream music moves from rock, to pop, to rap, seemingly overnight; dress hemlines go up or down with the seasons. But some of that might be an illusion, the researchers with this new effort contend, because of the way we view change.

Rate - Culture - Changes - Rates - Evolution

To compare the rate at which human culture changes to rates of biological evolution, the researchers assigned variables to characteristics of several cultural artifacts—whether or not guitars were the major instrument in the average song, for example, or how car features such as...
