Evolution

HideShow resource information

1. 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.
  • Showed how genetic mutation can result in natural selection.
  • The idea of MRSA suggested that evolution can occur due to mutations.
  • Religion finally corresponded with the idea.

2. 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. What is the theory of evolution?

  • 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

4. 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. 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.
