working on a paper I'll throw up here when done looking at the assorted ways creative imaginative-types (artists, authors, etc) generate other races and/or cultures. I'll basically be exploring major archetypes and wanted to give you guys the chance for recommending or providing further examples. There's nothing that says a race or creature is bound by a single archetype. Will post the large swaths I have:
Humanoid - self explanatory
Cultural/Regional Appropriation - various combination of assorted and selected traits or cultures
Anthropomorphic - Creatures ranging from Humanoid to Beastial
Synthetic - including Robots
Pop Culture Appropriation
Not sure where I'll take the discussion if I build something like a flow chart of just a pool of similar types. May look into possible real-world ways breeds/species evolve and change.
