EVOLUTION

any process of formation or growth; development. —Scientology 0-8 Glossary (app 11.7.90)

there are four evolutionary tracks, evidently. Organism evolution, through natural selection, accident and (evidence suggests) outright planning. Mest evolution, brought about through the agency of life organisms. Theta evolution, a postulated process of learning in theta as a whole or as entities. And present time ladder-of-support evolution, in which less complicated organisms support more complicated organisms. (SOS Gloss)
