Several organisms, primarily protists, have what are called intermediate mitotic organisation. What is the most probable hypothesis about these intermediate forms of cell division?
A) They represent a form of cell reproduction that must have evolved completely separately from those of other organisms.
B) They rely on totally different proteins for the processes they undergo.
C) They may be more closely related to plant forms that also have unusual mitosis.
D) They show some but not all of the evolutionary steps toward complete mitosis.

Question

Quizplus · Accepted Answer

Intermediate mitotic organisation suggests that these organisms are undergoing some but not all of the evolutionary steps toward complete mitosis. This implies that they are related to organisms that undergo complete mitosis, but have not yet fully evolved the necessary components for it. This also suggests that they may share some components with other organisms, but have distinct differences in their mitotic machinery.
