I imagine the Protohumanoids seeded the Sargonians, and the Sargonians seeded the Vulcans per TOS episode. I’d forgotten about the line about Sargon’s people maybe seeding Vulcan and also thought Protohumanoids, but I think we can have both. Again, it doesn’t have to be Sargon’s people who originated or passed down the prophesy, but I’m trying to minimize the number of ancients we’re talking about, whether or not that’s necessary or right. How could the Mintakans fit into all of this? Were they a different kind of Sargonian seeding that’s taking longer? A Protohumanoid seeding? Did Sargonians look Vulcanoid? Or could they be the initial stock the Sargonians tweaked and deposited on Vulcan? I can’t remember from the episode how blasé they were about Vulcanoids evolving on their own on another planet. ...then again, plenty of humanoids do, so maybe mo tie is necesssry between the Mintakans and Vulcans.
