Evidence of Evolution

  • Darwin’s voyage and descent with modification
  • Evidence of evolution: fossil record, biogeography, comparative anatomy (homologous and analogous structures), comparative embryology, molecular biology

Darwin’s Theory and the Modern Synthesis

  • Natural selection and artificial selection
  • Modern synthesis and population genetics
  • Microevolution
  • Hardy-Weinberg Principle (population size, isolation, mutations, random mating, natural selection
  • Genetic drift: bottleneck effect, founder effect
  • Gene flow
  • mutation

Variation and Natural Selection

  • Polymorphic populations, clines, heterozygote advantage, neutral variation
  • Darwinian fitness
  • Types of natural selection: stabilizing selection, directional selection, diversifying selection
  • Sexual dimorphism
  • Limits of natural selection

Concept of Species

  • Biological species concept, ring species
  • Other species concept: morphological species, genealogical species, ecological species
  • Reproductive barriers: prezygotic barriers (temporal, habitat, behavioral, mechanical, gametic), postzygotic barriers (hybrid inviability, hybrid sterility, hybrid breakdown)

Mechanisms of Speciation

  • Geographic isolation and allopatric speciation
  • Adaptive radiation
  • Sympatric speciation and polyploidy
  • Gradualism vs. punctuated equillibrium

Earth History and Macroevolution

  • Macroevolution and the geologic time scale
  • Radiometric dating
  • Continental drift: Pangea, Laurasia, Gondwana, plate tectonics
  • Mass extinctions
  • Exaptation
  • Evo-Devo and paedomorphosis
  • Phylogenetic trees and cladistics

Systematics and Phylogenetic Biology

  • Systematic classification
  • Convergent evolution: homology vs. analogy
  • Molecular comparisons: protein comparisons, DNA and RNA comparisons, molecular clocks
  • Cladistic analysis

The Domains of Life

  • Three domain system

Early Earth and the Origin of Life

  • Early Earth environment
  • Origins of life, Miller-Urey
  • Ribozymes and RNA world
  • Molecular cooperatives

Animal Evolution and Diversity

  • Characteristics of animals
  • Origins of the animal kingdom

Invertebrates

  • Porifera: radial symmetry, body plan, nutrition and digestion
  • Cnidaria: radial symmetry, body plan, life cycle, nutrition and digestion, development
  • Platyhelminthes: bilateral symmetry, nutrition and digestion, flukes, tapeworms, body cavities, disease
  • Nematoda: body plan, nutrition and digestion, C. elegans, diseases
  • Mollusca: body plan, gastropods, bivalves, cephalopods
  • Annelida: segmentation, earthworms, polychetes, leeches
  • Arthropoda: body plan, horseshoe crab, arachnids, crustaceans, centipedes and millipedes, insects (types of metamorphosis)
  • Echinodermata: radial symmetry, body plan, water vascular system

Vertebrates

  • Features of Chordates: nerve chord, notochord, pharengeal gill slits, post-anal tail
  • Tunicates and Lancelets
  • Vertebrates characteristics: skull and backbone, hinged jaws
  • Chondricthyes and Osteichthyes
  • Amphibians
  • Reptiles and amniotic eggs
  • Birds
  • Mammals: monotremes, marsupials, eutherials

Phylogeny of the Animal Kingdom

  • Evolutionary trends: tissues, symmetry, body cavity, coelom
