  • The theory of evolution is based on the idea that all species are related and gradually change over time.
  • Evolution relies on there being genetic variation in a population which affects the physical characteristics (phenotype) of an organism.
  • Some of these characteristics may give the individual an advantage over other individuals which they can then pass on to their offspring.

  • Charles Darwin’s theory of evolution states that evolution happens by natural selection.
  • Individuals with characteristics best suited to their environment are more likely to survive, finding food, avoiding predators and resisting disease. These individuals are more likely to reproduce and pass their genes on to their children.
  • Individuals that are poorly adapted to their environment are less likely to survive and reproduce. Therefore their genes are less likely to be passed on to the next generation.

  • When the same adaptations evolve independently, under similar selection pressures.
  • For example, flying insects, birds and bats have all evolved the ability to fly, but independently of each other.

  • When two species or groups of species have evolved alongside each other where one adapts to changes in the other.
  • For example, flowering plants and pollinating insects such as bees.

    • When a species splits into a number of new forms when a change in the environment makes new resources available or creates new environmental challenges.
    • For example, finches on the Galapagos Islands have developed different shaped beaks to take advantage of the different kinds of food available on different islands.
