πŸ“š 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.
  • πŸ¦‹ 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.
  • πŸ’‘ Adaptation: A trait that enhances an organism's survival and reproduction in its environment.
