Skills
- analyze (how natural selection produces change in populations and not in individuals) #dok3
- evaluate (the effects of natural selection at the population and individual level) #dok3
- distinguish (between changes occurring in populations versus individuals due to natural selection) #dok2
Learning Targets
- I can describe the process of natural selection. #dok1
- I can identify the levels at which natural selection operates. #dok1
- I can distinguish between changes in populations and changes in individuals as a result of natural selection. #dok2
- I can analyze examples of how natural selection leads to population-level changes over time. #dok3
- I can evaluate case studies to determine whether natural selection is acting at the individual or population level. #dok3
Big Ideas
- Natural selection acts on genetic variation within populations, leading to evolutionary change over time.
- Evolution occurs at the population level, not at the level of individual organisms.
Essential Questions
- How does natural selection cause changes in populations but not in individual organisms?
- What evidence supports that natural selection operates at the population level?
- Why do individual organisms not evolve during their lifetimes, but populations do over generations?
- How can studying populations over time reveal the effects of natural selection?
- In what ways does natural selection contribute to the diversity of life?
