- There is a fit between organisms and their environments, though not always a perfect fit. (LS4.C)
- Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)
- A hallmark of science is exposing ideas to testing. (P3, P4, P6, P7)
- Scientists test their ideas using multiple lines of evidence. (P6, NOS2)
- Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data. (P2, P3, P4, NOS1)
- Scientists use experimental evidence to study evolutionary processes.
