- Natural selection and genetic drift act on the variation that exists in a population.
- Variation of a character within a population may be discrete or continuous.
- Organisms cannot intentionally produce adaptive mutations in response to environmental influences.
- 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.
- Natural selection is capable of acting at multiple hierarchical levels: on genes, on cells, on individuals, on populations, on species, and on larger clades.
- Scientists test their ideas using multiple lines of evidence.
- Scientists may explore many different hypotheses to explain their observations.
- Scientists use experimental evidence to study evolutionary processes.
