Name: Date: Confrey Biology H Evolution Unit Outline Pre-Unit Assignment: Outline the following objectives. Once the unit is complete, all objectives should be thoroughly targeted. Evolution Eye Text: p292-349 Key Objectives: A. Define evolution & outline evidence of evolution. 1. Fossil Record, fossil dating, and correlation 2. Comparative anatomy: homologous vs. analogous structures; vestigial structures; embryological development 3. Molecular evidence 4. Artificial Selection B. The Origin of Life 1. Compare and Contrast spontaneous generation (abiogenesis) and biogenesis i. Explain the experimental significance of Francesco Redi and Louis Pasteur 2. Describe the significance of Oparin. 3. Describe the conditions thought to have existed on early Earth. 4. Outline the major steps hypothesized to have occurred in the origin of cells [heterotroph hypothesis]. 5. Explain how the evolution of photosynthetic autotrophs affected the atmosphere. 6. Outline and explain the Urey-Miller experiment and its significance [1950s]. 7. Describe the endosymbiont theory and summarize the evidence supporting it. C. Define the term extinction. How does this apply to evolution? D. Compare and contrast the work of Lamarck and Darwin. 1. Lamarck – Use and Disuse, Inheritance of Acquired Characteristics i. Weismann’s Experiment 2. Darwin – Theory of Natural Selection i. overproduction, competition, variation, adaptation, natural selection, and speciation ii. Weaknesses of Darwin’s Theory 3. Identify various types of natural selection i. direct, stabilizing, & disruptive selection ii. read a trait distribution graph E. Outline and explain incidences of “observed natural selection.” 1. Peppered Moth 2. Insecticides 3. Bacterial Resistance F. Define the term species [biological species concept]. Define the term Speciation. G. Population Genetics: Speciation & Macroevolution 1. Compare and contrast geological and reproductive isolation. 2. Explain the concepts of adaptive radiation, co-evolution, and convergent evolution, divergent evolution 3. Identify causes of evolution of a population: mutations, natural selection, and genetic drift – bottle necking & founder effect, gene flow 4. Variation → Isolation (geographic) → Natural Selection (environment selects)→ Divergence (accumulation of differences)→ New Species (speciation) H. Hardy 1. 2. 3. Weinberg Equilibrium Define population, population genetics, genetic equilibrium, and microevolution. Distinguish between genotype, phenotype, and allele frequencies. Discuss the significance of the Hardy-Weinberg principle as it relates to evolution, and list the FIVE conditions REQUIRED for genetic equilibrium. 4. Solve population genetics problems based on the Hardy Weinberg equation. i. Where p = frequency of the dominant allele; q = frequency of recessive allele. 1. p + q = 1 (1 represents 100% of the population) 2. p2 + 2pq + q2 = 1 I. Compare and contrast punctuated equilibrium with gradualism [timing of evolution].
