- Geological change and biological evolution are linked.
- 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.
- Variation of a character within a population may be discrete or continuous.
- 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.
