Evolution

• Evolution

  A change in the inherited characteristics of a population over time through natural selection which may lead to a new species
• The theory of evolution states that all species of living things evolved from simple life forms over 3 billion years
• How has the zebra evolved to run quicker? (4)

  • Variation among zebra population so some are faster
  • Zebras that run faster are more likely to survive
  • More likely to reproduce and pass on beneficial characteristics
  • Repeats over multiple generations
• Evidence for evolution

  • Evidence for Darwin’s theory is now available as it has been shown that characteristics are passed on to offspring in genes
  • There is further evidence in the Fossil Record and the knowledge of how resistance to antibiotics evolves in bacteria
