- Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)
- Natural selection acts on the variation that exists in a population. (LS4.B, LS4.C)
- 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. (LS4.B, LS4.C)
- Scientists test their ideas using multiple lines of evidence. (P6, NOS2)
- Scientists use experimental evidence to study evolutionary processes.
- Scientists may explore many different hypotheses to explain their observations. (P7)
