- There is a fit between organisms and their environments, though not always a perfect fit.
- Evolution results from selection acting upon genetic variation within a population.
- Traits that confer an advantage may persist in the population and are called adaptations.
- Inherited characteristics affect the likelihood of an organism's survival and reproduction.
- The amount of genetic variation within a population may affect the likelihood of survival of the population; the less the available diversity, the less likely the population will be able to survive environmental change.
- Scientists test their ideas using multiple lines of evidence.
- Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data.
