It does. It uses Maildir.

Yes, and that's the issue. It's the configuration and indexing
databases that evolve.

Evolution doesn't store messages in a database.

Every installation of Evolution has, or should have, the internal help
files installed. That has sections not only on Backup/Restore and
syncing data, but also a section on storage locations.  For local "On
this Computer" mail, then look in ~/.local/share/evolution/mail/local/
 
Please, though, don't go modifying or playing with Evolution's internal
files. It will confuse things and will likely lead to data loss.
