Evolution: Was the nuclear-to-cytoplasmic ratio a key factor in the origin of animal multicellularity?

The ichthyosporean Sphaeroforma arctica, a protist closely related to animals, displays coenocytic development followed by cellularization and cell release. A new study reveals that the nuclear-to -cytoplasmic ratio drives cellularization in these fascinating organisms.
