Domestication

  1. agriculture
    the production of goods through the growing of plants, animals and other life forms


    
  2. Domestication
    the genetic alteration of plants or animals as a result of human control of reproduction
  3. Artificial Selection
    selective pressures applied by humans (rather than natural environment)
  4. Characteristics chosen to domesticate plants
    • fast growth rate (e.g., annuals)
    • easily stored
    • easy to grow
    • plentiful
    • generally high nutritional quality
  5. Common genetic changes in Domesticates (direct effects)
    • increased yield (more seeds, larger size)
    • more effective
    • harvesting/processing
    • loss of seed-dispersal mechanisms
    • consistent & short-ripening time
    • easier processing
    • better taste
    • greater docility (animals)
  6. Common genetic changes in Domesticates (indirect effects)
    • loss of defense mechanisms / competitive abilities
    • less genetic diversity
