Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- There is a fit between organisms and their environments, though not always a perfect fit.
- Evolution results from natural selection acting upon genetic variation within a population.
- Traits that confer an advantage may persist in the population and are called adaptations.
- An individual’s fitness (or relative fitness) is the contribution that individual makes to the gene pool of the next generation relative to other individuals in the population.
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.
- Scientists test their ideas using multiple lines of evidence.
- 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.
