    1. Genetics & Evolution Chapter 19-25

    2. Evolution Creationism is a religion Cannot be disproven via testable experiments Intelligent Design (a bridge? Not really) Cannot be disproven with experiments either Evolution Changes regularly to maintain agreement with experiments Makes predictions about future and past that may be tested and thus disproven

    3. Darwin Finches Galapagos islands Usually 2-3 species of finch per island Each species very well adapted to eat specific seeds (depening on shape and size of beak) Climate changes produce hybrid breeding sometimes and changes in species populations 13 species that are distinct but from an evolutionary point of view very similar

    4. Micro versus Macroevolution Micro used to describe shifts in genotypes within a population Macro implies new species Finch work (and others) in Galapagos indicates there is little or no difference between these two.

    5. Natural Selection Survival of the Fittest? Success at adaptation and filling ecological niches Pepper moth of Britain during industrial revolution
