2. How did the discovery of genetics support Darwin's idea.

  • Religion finally corresponded with the idea.
  • It provided an explanation of how organisms born with beneficial characteristics can pass them on.
  • The idea of MRSA suggested that evolution can occur due to mutations.
  • Showed how genetic mutation can result in natural selection.

3. Describe how evolution can occur due to mutations.

  • A mutation is a change in an organisms DNA, occasionally they can be beneficial by producing a useful characteristic. this characteristic may give the organism a better chance of surviving and reproducing.
  • A mutation is a broken DNA, occasionally they can be beneficial by producing a useful characteristic. this characteristic may give the organism a better chance of surviving and reproducing.
