Review Sheet Evolution (chapters 15, 17 (17.1) Key Words Natural Selection Speciation Population Allelic frequency Geographic Isolation Reproductive Isolation Temporal Isolation Behavioral isolation Gene pool Vestigial Structures Homologous Structures genetic drift gene flow stabilizing selection directional selection disruptive selection Objectives 1) Understand the basic components of Darwin’s theory and how it accounts for evolutionary change 2) Explain how natural selection applies to numerous situations, from antibiotic resistant bacteria and to Darwin’s finches 3) Explain the difference between mimicry and camouflage and give an example of each. 4) Understand how the fossil record, homologous/vestigial structures, embryological similarities, and molecular comparisons (DNA, RNA, and protein) provide evidence for evolution 5) Describe the different types of natural selection (directional, stabilizing, and disruptive) and give an example that illustrates each (use pg. 408 of your book for help) 6) Explain why an individual cannot evolve but a population can. Use an example to illustrate your reasoning. 7) Explain which factors cause changes to the gene pool of a population 8) Be able to explain what the process of speciation is how the different types of isolation (geographic, temporal, and behavioral) cause this to happen 9) Explain what is meant by reproductive isolation 10) Understand the taxonomic system for classifying organisms and be able recognize how closely related two organisms are based on their taxonomic similarities.
