Evolver

Evolver is a term used in various disciplines to denote an agent or mechanism capable of undergoing or driving evolutionary change. There is no single, universal definition, and usage tends to be contextual, drawing on the root idea of evolution—change over time through heritable variation and selection.

In biology and education, evolver is sometimes used informally to refer to a lineage, population, or organism that has experienced evolution, or to an instrument for illustrating evolutionary processes. It is not a formal taxonomic or scientific designation.

In computing and artificial life, an evolver is more precisely defined as a component or program that maintains a population of candidate solutions and applies variation and selection to drive improvement. Evolvers are central to evolutionary algorithms, genetic programming, and related methods used for optimization, automated design, and machine learning.

In popular culture, evolver is often used as a fictional device, character, or concept associated with mutation, transformation, or adaptive change. When used, it is typically a metaphor or plot element rather than a technical term.
