Video Learning Notes
Natural selection causes some traits in populations to increase or decrease over generations based on their impact on survival and reproduction. Using mathematical tools like ratios and graphs helps students analyze and explain these changes with evidence. Understanding this process reveals how species adapt to their environments over time.
Learning Goals
- Use mathematical representations to explain how natural selection leads to increases or decreases of specific traits in populations over time.
- Analyze data patterns related to trait frequency changes in populations.
- Construct scientific explanations supported by evidence about natural selection and adaptation.
