real life examples of evolution

📚 Quick Study Guide

• 🌱 Natural Selection: The process where organisms better adapted to their environment tend to survive and reproduce more successfully.
• 🦠 Antibiotic Resistance: Bacteria evolving to withstand antibiotics.
• 🦋 Industrial Melanism: The adaptation of moths to darker environments during the Industrial Revolution.
• 🐦 Darwin's Finches: A classic example of adaptive radiation, where finches on the Galapagos Islands evolved different beak shapes to exploit various food sources.
• 🧬 Mutation: A change in the DNA sequence that can introduce new traits.
• 🌍 Geographic Isolation: Populations separated by physical barriers can evolve differently, leading to new species.
• 💡 Adaptation: A trait that enhances an organism's survival and reproduction in its environment.
