• [Mechanisms of evolution: Grades 9-12] Evolution results from selection acting upon genetic variation within a population. (LS4.B)
• [Mechanisms of evolution: Grades 9-12] Natural selection acts on the variation that exists in a population. (LS4.B, LS4.C)
• [Mechanisms of evolution: Grades 9-12] Inherited characteristics affect the likelihood of an organism's survival and reproduction. (LS4.B, LS4.C)
• [Mechanisms of evolution: Grades 9-12] Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)
• [Mechanisms of evolution: Grades 9-12] Natural selection is dependent on environmental conditions.
• [Mechanisms of evolution: Grades 9-12] Over time, the proportion of individuals with advantageous characteristics may increase due to their likelihood of surviving and reproducing. (LS4.B, LS4.C)
• [Mechanisms of evolution: Grades 13-16] Evolution results from natural selection acting upon genetic variation within a population.
• [Mechanisms of evolution: Grades 13-16] Natural selection and genetic drift act on the variation that exists in a population.
• [Mechanisms of evolution: Grades 13-16] Inherited characteristics affect the likelihood of an organism's survival and reproduction.
• [Mechanisms of evolution: Grades 13-16] Over time, the proportion of individuals with advantageous traits may increase (and the proportion with disadvantageous traits may decrease) due to their chances of surviving and reproducing.
• [Mechanisms of evolution: Grades 13-16] Traits that confer an advantage may persist in the population and are called adaptations.
• [Nature of science: Grades 9-12] Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence. (P4, P6, NOS3)
