Document Summary
Redi"s experiment to test spontaneous generations of maggots (meat covered and uncovered) Pasteur"s experiment to test spontaneous generation of bacteria. Both tested the same null hypothesis, both had appropriate controls. Chemical gradients can be used to store energy (ex//neurons have ions that go across the plasma membrane to communicate and store energy) Links a phenotype to the same space as the genotype that encodes it. Defn-form of natural selection where humans drive the course of evolution. Repeating this process over generations results in changes in the characteristics of a domesticated population over time. Happens by selecting individuals of extremes (chihuahua, corn, cows,) Broccoli, cabbage, kale came from brassica oleracea: before artificial selection most plants have a small stalk, after one cross of wide-stalked individuals, the average stalk width of progeny is slightly larger, eventually average phenotype is dramatically shifted. Its not the individual changing, it"s the population changing over time.
