Engine Of Evolution Chapter Summary

477 Words2 Pages

Very similar to previous chapters, is the process of natural selection, so the Engine of Evolution gives a look at the various forms of evolution and explains the possibilities. Seems like evolution contains many separate subjects that all explain a very complicated theory, however, by learning more, we prepare ourselves with knowledge about the truth. Evolution represents the scientific community’s version of our origins, and the best supporting evidence are natural selection and adaptation. Since, Jerry Coyne used chapter 1 to explain the basic concept of evolution, like the six point evolutionary theory; however, he uses chapter 5 for more detail on the concepts like: the process of evolutionary change through natural selection & adaptation, and laboratory evolution. Because, Jerry Coyne, covered this idea of evolutionary change earlier in the book, his focus is on the genetic drift and natural selection being the cause for evolution, during this chapter. Therefore, pileated woodpecker are an example of an animal with adaptations that are beneficial, like the reinforced skull, and a beak that is re-enforced by cartilage. Another, factor at work creating genetic variations are …show more content…

New studies and experiments like laboratory adaptations are far more complex, than natural ones. In like manner, Jerry Coyne describes the relation between the natural selection, and the evolution process of bacteria. In other words, those diseases and bacteria also evolve and become resistant to antibiotics, and the diseases and viruses also evolve to resist certain medications. The HIV virus is a good example of viruses becoming resistant to medication, because it became resistant to azido thymidine. This reality is scary for future generations of humans trying to survive through more resistant and dangerous diseases and
