Level 1 Evolution Review Guide Organize your materials in the following order: 1. Notes packet containing the following: Evolution, fossil evidence Biogeographical evidence Anatomical evidence Biochemical evidence Charles Darwin & natural selection Adaptations v. variations Stabilizing, directional & disruptive selection Population genetics, gene pool, Hardy-Weinberg, conditions for H-W 2. 3. 4. 5. 6. Microevolution, coevolution, convergent evolution, divergent evolution Specie v. hybrids Process of speciation, allopatric, sympatric, adaptive radiation Pace of speciation Video questions (even if you were absent, you are still responsible for the information) Darwin article questions Hardy-Weinberg reading Worksheet – types of natural selection & evolution Allele frequency lab (popsicle sticks) Test questions will be based on the following main ideas: Identify and describe the 4 types of evidence used to describe how evolution has occurred. 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? 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 explain the process and identify examples of natural selection as seen in the video – describe the organism, the traits selected, and why. Know the background about Darwin’s voyage and why his ideas were so controversial in his time. Be familiar with how Malthus and Lyell influenced Darwin’s theory of natural selection, and what finally motivated Darwin to publish his book. 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? 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 would NOT apply (ex: genetic drift). Be able to identify the difference between coevolution, convergent evolution, and divergent evolution with examples of each. Be able to explain why two members of different species would be reproductively isolated from one another. Be able to compare allopatric speciation and sympatric speciation and give an example of each. Be able to compare the two hypotheses concerning the pace at which evolution occurs.
