It's likely an interpretation of species as families. As in, those that belong to the same species belong in the same family. As we know, Gaster is likely a font skeleton.

There's actually more evidence for this, but the fandom doesn't really present this more obscure evidence. MatPat did in his Gaster theory, but he reached a completely different conclusion.... Which ended up contradicting itself later on. (If Sans and Papyrus were two halves of Gaster, Gaster couldn't have spoken to Sans in Entry 17) ...Well, this is the same theorist who made the Sans is Ness theory, so, what should we expect from him?
