Why can some mutations be beneficial?

  • Occasionally, mutations can be beneficial.
  • For example, if a different protein is produced, then it could actually be an improvement on the old one.
  • This can give the organism a survival advantage over others in its population.
  • This can lead to natural selection and evolution over time.
  • Mutations can also cause resistance to some illnesses.
