This nets out as a Gaia notion for those that seek to assign consciousness.
Should one go all Hari Seldon on it, one could imagine other Gaia's, they fundamentally distinct, and a time and a place where they meet.

Until we meet another Gaia, we are one, when we meet, there will be two, the alleles of Luca, and the alleles of another.
