The initial chapter of this book reveals how Coyne critically defines each keyword essential in the evolutionary theory. A fascinating finding is the author simply defines evolution as change over time. This approach is diverse from the manner other writers have given different meanings to the term ‘evolution. Looking at several articles, various writers have defined evolution as change in allele frequency over time, sufficiency of neo-Darwinian mechanism i.e. mutation, drift, and selection, and the universal common ancestry. With the way Coyne has explained the term ‘evolution, readers can understand clearly the term, this is in contrast to the manner other writers who have tackled the evolution have confused readers. This does not mean that the author disputes the fact that allele frequency change over a given time frame, in addition,, he does not disagree on the concept of natural selection in the evolution process. According to my own understanding, Coyne has embraced the concept of common ancestry, thus this out-rules any controversial issue (Coyne, 2009).
In this chapter, the key points revolve around the truth of gradualism and natural selection, as well as mutations to account for the diversity in life. In this chapter, Coyne goes on to defend common ancestry as a foundation of evolution.
This chapter deals with fossil evidence as a component of common ancestry. In the initial part of this chapter, the author outlines the process of fossilization. He also provides an introduction to radioisotope dating techniques; useful in approximating the time of life of rocks. The author goes on to say that fossil data simply shows a trend of simpler living beings preceding more complex ones. This is a perfect evidence of common ancestry (Coyne, 2009).
This chapter covers three evolutionary transitions that were documented by the fossil record. They are the evolution of

Life came from a molecule and from this molecule evolved different life forms. This is truth supported by evidence, according to evolutionists. But life is the result of “intelligent design,” a deity who breathed life into the “nostrils” of man. And that needs no evidence.
Charles Darwin’s theory of natural selection stipulates that evolutionary changes occur through production of different genotypes and differential survival of individuals with different combinations of
The writer states that life on earth has evolved gradually and it began with only one primitive species as a self-replicating molecule that existed 3.5 billion years ago. The paper describes the evolution fact, how genetics have changed overtime, the whole idea of gradualism and the many generations in which evolution has undergone.
This paper provides a critical reflection on every chapter of the book in an attempt to get deeper understanding of evolution.
This is the introductory part of the book. In my view, the book covers key
The essay shall firstly review every chapter as a demonstration of the scientific concepts of evolution. As a summary, at the end of the essay, other concepts of evolution based on Philosophy, Theology and
On the other hand, disruptive selection occurs when extreme traits are chosen over intermediate traits whereas stabilizing selection is when intermediate traits are selected over extreme traits.
8. Genetic drift and mutation can lead to
According to the paper, life on earth was; as a result, of the creation by a divine force. Most religions believe in a common concept of creation by a Supernatural Being. A commonly accepted account of this theory is found in the Bible, which is inscribed that God created the earth and all its content in five days.
For a lengthy period of time, a number of controversial issues between evolution and religion have been identified. In itself, evolution has been factored in as an issue of debate. However, the effort channeled to see to it that instructional approaches address the inherent controversy between religion and evolution- as theories on the existence of the world and its inhabitants- is quite minimal.
