- 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.
- 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.
