Evolution

 
I use evolution in a loosely, orderly and developmental sense of milestones and mainly in a psychological sense, but also in a wider species context.

The content of the picture usually demonstrates two stages of evolution where the one metamorphoses into another; perhaps a next or higher stage. Some works in this grouping tend to a linear categorization; while others depict a more intuitive way of transcendence.

The word evolution carries the seed of a “solution” in it, which points to some sort of integration!
