Bio 1 Evolution Study Guide Test questions will be based on the following main ideas: Know the three people and their theories that Darwin used in his evidence (Cuvier, Hutton, and Lyell). Know the background behind Darwin’s theory and the voyage and why his ideas were so controversial in his time. Identify and describe the 4 types of evidence used to describe how evolution has occurred (anatomical, comparative embryology, biogeography, and biochemical). Explain what each type of evidence for evolution can tell us about organisms, and give an example to support each. Several examples: By looking at the fossil remains, or those found nearby, what do scientists know about the organism? Think relative dating versus absolute dating. What do homologous, analogous, and vestigial organs tell us about the organisms they come from? What can we tell about organisms by comparing their embryos? What can we learn by comparing life forms from various geographical regions? What is learned by comparing biochemical data from various organisms (proteins, DNA, etc.)? Be able to construct a cladogram from DNA data provided from BLAST. Be able to contrast Darwin’s explanations for organism change to that of Lamarck. Be able to explain the difference between an adaptation and variations in a population. Where do variations come from? What are some different types of adaptations and examples of each? (Variations lead to adaptations) Be able to identify and describe 3 ways that natural selection can act on a population – stabilizing, directional, and disruptive selection – be able to give an example of each. Be able to explain the Hardy-Weinberg Law, apply the math if given some information about a population, and identify and describe situations in which the law MUST apply. Also be able to predict how the allelic frequency should change as some situations change (ex: genetic drift). Explain the 5 agents of evolution and how the combination of these agents leads to evolution. Be able to identify the difference between coevolution, convergent evolution, and divergent evolution with examples of each. Be able to explain the several reasons how two members of different species could be reproductively isolated from one another. Be able to compare allopatric speciation and sympatric speciation and give an example of each.
