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. How did the discovery of genetics support Darwin's 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.
  • Religion finally corresponded with the idea.
  • Showed how genetic mutation can result in natural selection.

3. What do evolutionary trees show?

  • Types of organisms and relationships between them.
  • Common ancestors and relationships between organisms. The more recent the common an
  • Whether there are any common ancestors.
  • How trees evolved over 3 Billion years.

4. 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.

5. What is the theory of evolution?

  • 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 Million 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
