Coyne’ s has laid a great deal of importance on mutation in the third chapter. He says about the mutation witnesses of evolution including vestigial organisms (Coyne, 2009). Such poorly designed and useless features provide strong evidence that supports Coyne’ s theory. He further provides good evidence of laryngeal nerve which runs from the throat to the aorta and back again. This chapter also faces some critics. Coyne does not clearly show how evolution and mutation are linked and therefore I would question how vestigial organs come into being and what resulted in their disappearance.

Furthermore, mutation is not enough to convince one that evolution occurred. One can as well argue that mutation occurs due to climatic changes in the world and not as a result of evolution (Shubin, 2008). In fact, as he defined evolution, he did not mention anything related to mutation and the presence of poorly designed and useless features. Creationists claim that the creator created people in His own image and likeness then these organs come from one (Coyne, 2009). Does this mean that if we resemble our creator, then why would he not tell us that creator also evolved?

Therefore, his arguments were vague. The next three chapters including 5, 6 and 7 provide the strength of the book and talk about NE ontological arguments from genetics and speciation theory. He discusses how sex brings about evolution (Shute, 1961). This is a discussion that surprises anyone. It was discovered that sexual combination played a vital role in genetic variability and speciation. According to me, this statement just raises controversies and does not talk about evolution. The first critic is that it is not clear how sex brings about evolution.

Though it may result in genetic transfer, evolutionary genes are not transferred. Hence evolutionary genes may not be transferred to another person or organism. This discussion is shallow and cannot really influence my own understanding that sex is a driver of evolution (Shubin, 2008).
