3.1 Natural Selection, Adaptation and survival

Natural Selection, Adaptation, and Survival: How Life Changes Over Time

You will discover how natural selection shapes the traits of populations over generations, and how adaptations help organisms survive in their environments.

What You'll Learn

You learn how natural selection favors helpful inherited traits over generations.

You explore structural, behavioral, and physiological adaptations in living organisms.

You discover how variation within populations drives evolutionary change over time.

You connect natural selection to real examples like moths and antibiotic resistance.

What You'll Practice

You will analyze peppered moths and antibiotic resistance as natural selection examples.

You will match key terms like adaptation, fitness, and inherited trait definitions.

You will identify correct explanations for how populations change through natural selection.

Why This Matters

Understanding natural selection and adaptation helps you explain how and why life on Earth changes over time, connecting biology to real-world issues like disease resistance and species extinction.
