Apoptosis is a complex biochemical mechanism whereby a specific cell destroys itself under certain conditions, without injury to the cells around it. A literature review reveals that neo-Darwinists have been unable to explain how the mechanism for apoptosis could have evolved in a step-by-step process. The mechanism of apoptosis regulates cell life for the advantage of the organism as a whole and not for the mere advantage to the genes, as Dawkins proposed. Apoptosis supports the concepts of irreducible complexity and intelligent design.
