Thanasis Dinos examines "errors" of evolution from the cellular to the systemic level, focusing on brain functions.

Among the questions he raises are the following: Why does the digestive system intersect with the respiratory system, causing us to often choke when we eat? Why did humans stand upright and what problems arise from the upright posture? Why is there a blind spot in the human eye's retina? Why did the Boskop people, with their large brains, disappear? Why don't brain cells regenerate? Why are perception and memory imperfect functions? Is forgetfulness a biologically useful mechanism? Is love a bittersweet "error" of evolution? The author examines these and many other evolutionary problems, posing the tough question: Is there an all-knowing and all-powerful yet clumsy designer, or is man the product of a natural process, as supported by Darwin's Theory of Evolution?

After many years of laboratory experience, Thanasis Dinos argues that humans now have the scientific knowledge and social intelligence that will allow them to overcome the Darwinian inability to comprehend the concepts of evolution and natural selection. With humor and composure, the author argues that we too are products of the same process that gave rise to every other form of life, a realization of crucial significance for the uncertain future of the planet and our survival as a species.
