Using genetics alone, sure. But maybe there’s fossil or geochemical evidence of early organisms not belonging to any of the three surviving domains—or maybe we could estimate it just from statistics.
Maybe but I don’t think fossil evidence has enough information to confirm something isn’t from the main branch of the tree of life.
especially when some of that stuff took a while for us to realize it's even part of the same organism, or an organism at all.
