  • Editing with intent to disrupt, demean, or gain unfair advantage is against University Honor Code and subject to disciplinary action.
  • Conduct violations may result in severe sanctions.
  • Document is not anonymous; editing is tracked.
  • Final exam is comprehensive; emphasizes concepts over specific details.
  • New material between Midterm III and Final Exam is heavily emphasized.

Exam Content Overview

Midterm I

  1. Major Topics
    • Skills: Interpreting phylogenies.
    • Competency: Defending/clarifying misconceptions about evolution.
    • Understanding patterns providing evidence of common ancestry.
    • Theme: "The Danger of the Single Story" - scaling from single stories to many stories.
      • Examples: One gene -> many genes, Populations -> species, etc.
      • Refuting logical mistakes (e.g., single gene causing trait like “gay gene”).
    • Patterns of evolution: Molecular and morphological data.
    • Historical evolutionary patterns: Testable through examples like Tiktaalik.
    • Phylogeny: Representation and testing.
    • Earth's timeline: Multicellular life, major extinction events.
    • Darwin’s four postulates: Core of evolutionary process.
    • Misconceptions: Evolutionary theories vs. laws, human evolution from chimpanzees, teleology.

Midterm II

  1. Modern Synthesis
    • Post-Darwin understanding of evolution.
    • Blending vs. Mendelian inheritance.
    • Genetic variation and its translation into phenotypes.
    • Hardy-Weinberg Equilibrium: Allele/genotype frequencies, assumptions, deviations.
    • Genetic drift: Random sampling, role in evolution, connection to neutral theory.
    • Studying natural selection in the wild.
    • Flavors of Natural Selection: Identifying and organizing different types.
    • Polygenic/quantitative traits: Genetic correlations, constraints.
    • The Breeder’s Equation: Heritability and natural selection.

Material Between Midterm II and Final Exam

  1. Hardy-Weinberg and Human Evolution

    • Fisher’s geometric model: Evolutionary solution finding.
  2. Kin Selection and Levels of Selection

    • Inclusive fitness theory: Altruism evolution.
    • George Price and multi-level selection.
    • Major transitions: Group selection overpowering individual selection.
  3. Game Theory in Evolution

    • Evolutionary stable strategies (ESS): Frequency-dependent selection.
    • Evolution of cooperation and sex.

Kin Selection and Levels of Selection

  • Glossary: Inclusive fitness, Hamilton’s rule, altruism, group selection, etc.
  • History: Cooperation vs. conflict.
  • Naive group selection: Issues and arguments against.
  • Hamilton’s rule and inclusive-fitness theory: Coefficient of relatedness.
  • Multi-level selection: George R. Price's contributions.
  • Major transitions: Group selection, cancer in group selection.

Game Theory and Social Behavior

  • Terminology: Hawk-Dove game, ESS, payoff matrix.
  • Game theory: Frequency-dependent selection.
  • Hawk-Dove game and prisoner’s dilemma: Outcomes and strategies.
  • Iterated prisoner’s dilemma: Mixed strategies and winning characteristics.

Sexual Selection and Evolution

  • Terminology: Anisogamy, sexual dimorphism, Bateman gradients, etc.
  • Evolution of sex: Costs and benefits.
  • Sexual dimorphism: Evolutionary challenges and mechanisms.
  • Bateman gradients and mating systems: Implications for sexual selection.
  • Flavors of sexual selection: Direct/indirect benefits, runaway selection.

Evo-Devo: Adaptation and Evolutionary Novelty

  • Terms: Cis-regulatory elements, HOX genes, heterochrony, neoteny.
  • Transcription factors: Role in body patterning and evolution of new body plans.
  • Canalization and heterochrony: Importance in evolution.

Macroevolution and Human Evolution

  • Diversification vs. divergence: Macroevolutionary time studies.
  • Adaptive radiations vs. living fossils: Ecological opportunity, key innovations.
  • Extinction: Macroevolutionary Red Queen, background vs. mass extinction.
  • Human evolution: Major events, regional continuity vs. replacement hypotheses.

Additional Topics

  • Life History Evolution and Trade-offs: Resource allocation and optimality theory.
  • Coevolution: Reciprocal selection, species interactions.
  • Practice Problems: Various evolutionary concepts and scenarios.

Study Recommendations

  • Analyze payoff matrices for ESS.
  • Review graphs for each type of selection.
