Objectives for Evolution Test (Ch. 7) OBJECTIVE (The Student Will Be Able To…) # 1 Explain how genetic variation and environmental factors can together lead to evolution by natural selection. 2 List and describe evidence, collected by Charles Darwin, which led to his theory of natural selection. 3 Describe each of the independent lines of evidence supporting evolution: homologous structures, vestigial structures, embryological development, molecular structures (DNA/protein sequences), and fossils. 4 Compare Gradualism and Punctuated Equilibrium. 5 Explain why species may become extinct; explain what can cause a mass extinction event (such as the K/T extinction 65 mya) 6 Explain what a species is and how new species can form; how can a population be split in two (what can isolate populations?) 7 Construct a simple branching diagram to classify living groups of organisms by shared derived characteristics and expand the diagram to include fossil organisms. 8 Relate the worm/bird simulation (“color” and “beak size”) to natural selection. 9 Vocabulary: Identify the following terms or match to their definitions: species, fossil, adaptation, evolution, theory, natural STUDY Reading, workbook and notes, all activities and videos P224-231, bird beak adaptations, Wallace video P234-240, Evolution notes, Fossil Record Activity Great Transformations Video Dogs and More Dogs P240 P245-246, Extinction Video notes P 243 Grant video, Bird song activity P255-257; “What did T. rex taste like?” activity Lab notes Chapter 7, P.221 Vocab quiz selection, variation, comparative anatomy, homologous structures, vestigial structures, mold, cast, petrified fossil, trace fossil, gradualism, punctuated equilibrium, habitat, extinct, classification, prokaryote, eukaryote STANDARDS 3. Biological evolution accounts for the diversity of species developed through gradual processes over many generations. As a basis for understanding this concept: a. Students know both genetic variation and environmental factors are causes of evolution and diversity of organisms. b. Students know the reasoning used by Charles Darwin in reaching his conclusion that natural selection is the mechanism of evolution. c. Students know how independent lines of evidence from geology, fossils, and comparative anatomy provide the bases for the theory of evolution. d. Students know how to construct a simple branching diagram to classify living groups of organisms by shared derived characteristics and how to expand the diagram to include fossil organisms. e. Students know that extinction of a species occurs when the environment changes and the adaptive characteristics of a species are insufficient for its survival.
