- There is a fit between organisms and their environments, though not always a perfect fit. (LS4.C)
- Evolution results from selection acting upon genetic variation within a population. (LS4.B)
- Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)
- Scientists test their ideas using multiple lines of evidence. (P6, NOS2)
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence. (P4, P6, NOS3)
- Scientists use experimental evidence to study evolutionary processes.
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
- Fitness is reproductive success - the number of viable offspring produced by an individual in comparison to other individuals in a population/species.
