  • Scaffold This Builds On: 

    1. Definition(s) of life
    2. Patterns in life

    Mini Lecture:  Domains of life and lateral gene transfer

    Discussion: Evolutionary processes

    Game: Genome Evolution Game

    Key Concepts From This Class:

    1. Life can be classified in many ways (e.g. by morphology, function, genomes, etc.)
    2. Genomic classifications focus on evolutionary history, e.g. phylogeny
      1. Results do not give an unique branching tree
      2. Exchange of genes has strongly shaped evolution
    3. The Tree of Life is still being explored

    Scaffold for Future:

    1. Multiple paths of life
    2. Life solves evolutionary problems through different modes of evolution
