Evolution

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.

2. Why didn't everyone agree with Darwin?

  • Because it was against ancestral beliefs, Darwin couldn't explain himself, There wasn't enough evidence.
  • Because it was against common religious beliefs, Lamarck couldn't explain himself, There wasn't enough evidence.
  • Because it was against common religious beliefs, Darwin couldn't explain himself, There wasn't enough evidence.
  • Because it was against common religious beliefs, Darwin couldn't prove with an experiment, There wasn't enough data/information

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

4. What is the theory of evolution?

  • More than 3 Billion years ago, life on earth began as complex organisms evolved, rather than just randomly existing
  • More than 3 Billion years ago, life on earth began as simple organisms from which all the more complex organisms evolved, rather than just randomly existing
  • More than 3 Billion years ago, life on earth began as simple organisms from which all the less complex organisms evolved, rather than just randomly existing
  • More than 3 Million years ago, life on earth began as simple organisms from which all the more complex organisms evolved, rather than just randomly existing

5. 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.
