Animals and fungi predominantly use two completely different modes of cell division — known as open and closed mitosis, respectively. A brand new research has proven that completely different species of Ichthyosporea — marine protists which can be shut kin of each animals and fungi — use both open and closed mitosis, intently correlated as to whether the species has multinucleate life cycle phases. The research demonstrates the way in which animals do cell division might need developed lengthy earlier than animals themselves did and the way that is linked to an organism’s life cycle.
