(n.) That series of changes under natural law which involves continuous progress from the homogeneous to the heterogeneous in structure, and from the single and simple to the diverse and manifold in quality or function.

It is also applied to explain the existence and growth of institutions, manners, language, civilization, and every product of human activity.
