HideShow resource information

1. Why do species with similar characteristics often have similar genes?

  • Because they share a recent common ancestor, so they're closely related.
  • Because they all come from the same father/mother figure
  • Because they have mutations with their bacterium.

3. Describe how evolution can occur due to mutations.

  • MRSA is an example. A mutation which has accumulated in a population.
  • 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.

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

  • Showed how genetic mutation can result in natural selection.
  • It provided an explanation of how organisms born with beneficial characteristics can pass them on.
