- Evolution results from selection acting upon genetic variation within a population. (LS4.B)
- Mutations are random.
- Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)
- Inherited characteristics affect the likelihood of an organism's survival and reproduction. (LS4.B, LS4.C)
- 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)
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
- There is variation within a population. (LS3.B)
