One of the most incredible features of cellular life is the capability of self-replication. And built into the remarkable process of cell division are several checkpoints that ensure the success of this life or death cellular practice. But can a Darwinian mechanism take the credit for this elegant cellular system? On this ID The Future, host Andrew McDiarmid continues his four-part conversation with Dr. Jonathan McLatchie on the intelligent design and irreducible complexity of eukaryotic cell division. In this segment, Dr. McLatchie describes each checkpoint and the role it plays in successful self-replication. This is Part 3 of a four-part series.
