| development | 1.

The elaboration of a theme or subject; the unfolding of a musical idea; the evolution of a whole piece or movement from a leading theme or motive. <biology> Development theory, the doctrine that animals and plants possess the power of passing by slow and successive stages from a lower to a higher state of organization, and that all the higher forms of life now in existence were thus developed by uniform laws from lower forms, and are not the result of special creative acts.
