• EVOLUTION:

  describe as the change in species over time.
• EVOLUTION:

  also change in the allelic frequency in a population of species.

• SELECTION:

  some individuals leave behind more offspring than others.
• NATURAL SELECTION:

  environmental conditions
• ARTIFICIAL SELECTION:

  breeder selects for desired characteristics
• NATURAL SELECTION:

  1. Selection to avoid predators
  2. Selection for pesticide resistance
  3. Selection to match climatic condition
• ARTIFICAL SELECTION:

  1. Laboratory Experiments
  2. Agriculture
  3. Domestication
• LAMARCK'S THEORIES OF EVOLUTION:

  1. Theory of Need
  2. Theory of Use and Disuse
  3. Theory of Acquired Traits
• LABORATORY EXPERIMENTS:

  Experimental populations lie outside the range of initial population.
• AGRICULTURE:

  Generations of selection for desirable traits.
• DOMESTICATION:

  The process of domesticating animals and plants, which involves the process of selective breeding.
