🌿 Key Concepts Covered
• Natural selection
• Heritable traits
• Variation within populations
• Environmental pressures
• Survival and reproduction
• Adaptation
• Evolution over time
• Trait frequency changes in populations
• Evidence-based scientific reasoning
• Relationships between organisms and their environments
Students learn that populations contain natural variation and that some inherited characteristics can improve an organism’s chances of survival and reproduction. Over many generations, these advantageous traits may become more common within the population, resulting in adaptation.
