Natural selection vocabulary quiz

📚 Quick Study Guide

• 🌍 Natural Selection Definition: The process where organisms with favorable traits are more likely to survive and reproduce.
• 🌱 Variation: Individuals within a population show differences in their traits.
• 🧬 Inheritance: Traits are passed from parents to offspring.
• 💪 Differential Survival and Reproduction: Individuals with certain traits are more likely to survive and reproduce than others.
• ⏰ Time: Natural selection occurs over many generations.
• 💡 Adaptation: Over time, the population becomes better suited to its environment.
• 🧪 Key Scientists: Charles Darwin and Alfred Russel Wallace are the main guys.
