- An example of evolution is the theory started by Charles Darwin that theorizes about how humans came to be in their present form.
- an unfolding, opening out, or working out; process of development, as from a simple to a complex form, or of gradual, progressive change, as in a social and economic structure
- a result or product of this; thing evolved
- a movement that is part of a series or pattern
- a pattern produced, or seemingly produced, by such a series of movements: the evolutions of a fancy skater
