Level 1 Evolution Review Guide

Organize your materials in the following  Microevolution, coevolution, order: convergent evolution, 1. Notes packet containing the divergent evolution following:  Specie v. hybrids  Evolution, fossil evidence  Process of speciation,  Biogeographical evidence allopatric, sympatric,  Anatomical evidence adaptive radiation  Biochemical evidence  Pace of speciation  Charles Darwin & natural 2. Video questions (even if you were selection absent, you are still responsible for  Adaptations v. variations the information)  Stabilizing, directional & 3. Darwin article questions disruptive selection 4. Hardy-Weinberg reading  Population genetics, gene 5. Worksheet – types of natural pool, Hardy-Weinberg, selection & evolution conditions for H-W 6. 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.
