The first component is evolution that means a change that occurs in a period of time, speciation, gradualism, natural selection, common ancestry and the evolution change mechanisms that are non-selective (Coyne, 2009). Presently, people have come into agreement that there are different organisms in the planet earth that have existed over time, a large number of these organisms have inhabited the earth at different periods of time. Various scientists have come into consensus stating that natural selection is a major contributor to the evolution process. The scientific community has finally decided that they would never deviate from these particular viewpoints (Richards, 2001).
Significance of Fossils.
Chapter two of Coyne's book illustrates the significance of the fossil records in justifying the evidence of evolution; however, fossil records do not provide any factual basis when it comes to creationism. Creationists argue that organic groups lack transitional forms and this has led to various challenges regarding the diversity of life. Despite this fact, Jerry Coyne vehemently states that transitional forms are present. The importance of fossils is that, they provide evidential materials with the characteristics and features of missing links found in different organisms. Jerry Coyne refers to various findings in his effort to show the reliability of fossils in the evolution process. A good example is that fossils are evidential in supporting the view that fish ancestors emerged from amphibians and that dinosaurs have a close connection to birds. They might have emerged from the dinosaurs (Coyne, 2009).
Jerry Coyne strongly disapproves a common viewpoint of Darwinism that states, natural selection has led to significant development of biological innovations and argues the hypothesis needs the illustration of intermediate stages of the adaptive advantages (Coyne, 2009). A great demonstration that disapproves the Darwinian Theory in regard to its concept on evolution, Jerry Coyne provides an example of wings and illustrates how 20% of one wing is beneficial to an organism.
