Socio-political: Gradualism is the belief in progression to a goal by incremental steps, a series of gradual improvements, etc. This is essentially a cumulative process, in strategic terms, planning for a series of steps over time. This principle is applied in terms of social change, inferring the development of social constitutions and changes over a period. It may also be applied to political changes.
Biological: The gradual change of organisms through a progressive accumulation of modifications, often over long periods of time. This is a highly debated concept in biology, where evolutionary trends have also been seen to be rapid, but is a baseline concept in terms of general evolutionary theory.
