Natural Selection

• Darwin's finches are an example of how natural selection can lead to adaptations that allow individuals with certain traits to survive and reproduce more successfully.
• Natural selection is the process by which organisms better adapted to their environment tend to survive and reproduce more than those less well-adapted.
• The Galapagos Islands were formed by volcanic activity, which created different habitats such as rocky cliffs, sandy beaches, and grasslands.
• Different species of Darwin's finches have evolved specialized beaks adapted to their specific diets.
• Each habitat had its own unique set of challenges and resources, leading to the evolution of distinct populations of birds on each island.
• Survival of the Fittest

  Natural selection or “Survival of the Fittest” is a process by which an organism is best fit for the environment and is most likely to survive and reproduce. 
• Does "fittest" mean strongest?

  "Fittest" DOES NOT mean the strongest. For natural selection it means the animal most FIT for its environment.
• Natural selection and genetics

  Due to environmental factors these finches experienced natural selection. After many generations,the traits that enhanced survival became more widespread than those traits that did not. Over time, this has caused an adaptation in the species.
• How does natural selection work?

  Natural selection works by giving certain traits an advantage over others within a certain environment. / Survival of the Fittest
