No, the Serpent Crown serial only talks about how Lemurian blue-skinned water-breathers became green-skinned over time due to the influence of the Crown and their corrupt King Naga. It says nothing about where the water-breathers came from originally.

Uatu basically says "The Cataclysm happened, and Atlantis sank. Many years later, water-breathers moved into the ruins."
