Natural Selection in a Nutshell:

  • living things produce more offspring than the finite resources available to them can support
  • thus living things face a constant struggle for existence
  • the individuals in a population vary in their phenotypes - this variation is a result of sexual reproduction
  • some of this variation is heritable - it is a reflection of variation in genotypes (DNA)
  • those variants best adapted to the conditions of their life are most likely to survive and reproduce themselves - survival of the fittest
  • to the extent that their adaptations are heritable, they will be passed on to their offspring
