• [History of life: Grades 13-16] Evolutionary change can sometimes happen rapidly.
• [Evidence of evolution: Grades 13-16] Artificial selection provides a model for natural selection.
• [Mechanisms of evolution: Grades 13-16] Evolution results from natural selection acting upon genetic variation within a population.
• [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] Natural selection may favor individuals with one extreme value for a trait, shifting the average value of that trait in one direction over the course of many generations.
• [Studying evolution: Grades 13-16] Scientists use experimental evidence to study evolutionary processes.
• [Studying evolution: Grades 13-16] Scientists use artificial selection as a model to learn about natural selection.
• [Studying evolution: Grades 13-16] As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health.
