The evolution scientific theory was first postulated by Charles Darwin who argued that beings and new species came into being through a process called natural selection. The theory of natural selection is based on the notion of ‘survival for the fittest’ as forwarded by Darwin. According to Darwin, in order for species to survive, they produced more offspring to increase their probability of survival with varying traits among individuals. These traits infer upon species varying rates of reproduction and survival. Traits that infer these characteristics on individuals are inheritable from one generation to another with minute improvements or declines. Evolution is a process that occurs over time with some aspects being rapid while others take years to manifest. There exist criticism and resistance towards the acceptance of evolutionary theory by some quarters of society, and it is this paper’s aim to dispel some of these reservations and prove that evolution is real.
Neil Shubin’s book is meant to address the various instances in history that evidence has been gathered up to support the theory of evolution, and the notion of common ancestry. The book seeks to dispel any doubts that may exist in the minds of his readers that evolution exists and it is still taking place in the world around us. The primary goal of Shubin’s book is to shed light on the evolutionary process and how the common man can visualize the intricacies involved in the process. The first chapter of the book dwells on this by drawing an example from a zoo to describe the nested hierarchy of living things (Shubin, 2009). The author uses the example of the common limb ancestry of all land animals characterized by five fingers, a wrist, one major bone, and two lower bones. This strengthens the author’s argument that all living things are descendants of a common ancestor. Chapter one uses a hypothesis postulating that since land animals descended from a common ancestor with similar limb structure. then this evidence should be available. The transition from one stage of evolution to another and from a lower species to a higher one is recognized through the study of intermediates. Chapter one illustrates the evidence of these intermediates through a fish intermediate called Tiktallik (Shubin, 2009). This was an intermediate between a fish an amphibian indicating the movement from sea living to land-living animals (Shubin, 2009). The most compelling evidence from this fossil was the presence of a neck and the common bone and limb structure.
