I'd say that the answer to the last question, like so many, is very likely Tolkien.Looking again at the 32 (the 15 that have been in every edition, plus the 17 added if Basic D&D doesn't count)...
- Why were green and blue dragons considered too "advanced" for Holmes Basic? Was five just considered too many dragons, but three just right?
- What's made dryads a staple of the AD&D lineage? And not, say, nymphs (which were in most editions but have yet to appear in 5e).
- Why is the efreet the most essential genie, and not the more obvious djinn?
- Why do fire and hill giants stand above the other three classic giants? Hill giants seem like your standard mythical giant, so that's easy, but why fire? (Also, aren't they redundant with efreet?
- Do minotaurs fill a humanoid niche not filled in the original 15?
- Ghouls, mummies, and vampires have a horror-fiction lineage that explains their presence, but why wraiths?
