Which you can argue for, but doesn't stem from them being all almost twins.

I can say Humans are 99.6% genetically identical, and I can say nations are kinda like independent organisms (more sketchy a statement than for ants), but I definitely can't say Humans are 99.6% genetically identical, and thus nations are kinda like independent organisms.

"Ants are almost twins" is not the cause of "Ants are not really autonomous individuals"
