    1. Life as a problem solved through evolution
    2. Structure and function vary in organisms

    Mini Lecture:  Evolution 1

    1. Fitness as a concept for natural selection
    2. Speciation as a result of genetic isolation
    3. Neutral drift as an evolutionary process
    4. Revolutionary innovations

    Game: Genome Evolution Game 2 

    Key Concepts From This Class:

    1. Multiple evolutionary forces
    2. Divergence of “species” requires genetic isolation
    3. Neutral drift of function/genes with low selection provides diversity

    Scaffolding from this lecture:

    1. Selection depends on function
    2. Dependence of organisms on ecology
