Natural Selection Evolution Through Natural Selection “Survival of the fittest.” Physical Environment -climate -weather -soils Survivor Reproduction Genetic Diversity New Population Biological Environment -competition -predation -parasitization Model Agricultural Core Curriculum: Supplement University of California, Davis 231.T 1 Natural Selection Mutation and Natural Selection Change in Abilities or Appearance (Phenotype) Change in Genetic Material (Genotype) • Mutations are changes in the structure of the DNA due to copying errors in gamete formation or due to the effects of mutagenic substances. • Some mutations may cause the organism to fail to develop (lethal mutation). • Others may have little or no effect on an organisms success.
