Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.

  • 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 organism's survival and reproduction.

  • Over time, the proportion of individuals with advantageous characteristics may increase (and the proportion with disadvantageous characteristics may decrease) due to their likelihood of surviving and reproducing.

  • 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.

  • A hallmark of science is exposing ideas to testing.

  • Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data.

  • The real process of science is complex, iterative, and can take many different paths.

  • Science is a human endeavor.

  • 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.
