  5. All organisms have a predisposition to mutate, although the rate at which they do so varies depending on physiological and environmental factors.
  6. The outcome of mutations is unknown. It could be useful or harmful to mutants.
  7. Because the mutations are unclear, they could affect members of the same species in different ways, leading to the simultaneous birth of numerous related new species from the same ancestral species.
