Topic 7.2: Natural Selection
Learning Objective: 7.2.A
Describe the importance of phenotypic variation in a population.
Essential Knowledge: 7.2.A.1
Natural selection acts on phenotypic variations in populations.
Essential Knowledge: 7.2.A.2
Environments change and apply selective pressures to populations. Illustrative examples: Flowering time in relation to global climate change.
Essential Knowledge: 7.2.A.3
Some phenotypic variations can increase or decrease the fitness of an organism in particular environments. Illustrative examples: Sickle cell anemia; DDT resistance in insects.
Learning Objective: 7.2.B
Explain how variation in molecules within cells connects to the fitness of an organism.
Essential Knowledge: 7.2.B.1
Variation in the number and types of molecules within cells can provide populations a greater ability to survive and reproduce in different environments.
