  • Evolution results from natural selection acting upon genetic variation within a population.

  • Natural selection and genetic drift act on the variation that exists in a population.

  • Inherited characteristics affect the likelihood of an organismís survival and reproduction.

  • Traits that confer an advantage may persist in the population and are called adaptations.

  • Depending on environmental conditions, inherited characteristics may be advantageous, neutral, or detrimental.

  • As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health.
