1. Background
   1. Plant life occurs everywhere on the earth
   2. Each organism adapted to living in its own niche
   3. Without adaptation-Extinction
   4. Adaptation is the result of Natural Selection
2. The Process of Evolutionary Adaptaion
   1. Genetic Variation
      1. mutation
      2. sexual reproduction
      3. migration
   2. Competition to reproduce
   3. Natural Selection
3. Two unique examples of adaptation
   1. Coevolution
      1. Plants and their pollinators
   2. Symbiosis
      1. lichens-algae/clam
      2. clam/algae
      3. soybean/nitrogen fixing bacteria
