  • Natural Selection of a Tiger
  • Hi. My name is Tyrone. I am a tiger and I love laying in this grass and playing at this tree . I think its reproducing season.
  • Step 1: Overproduction of Offspring
  • We have overproduced to make sure that some of the offspring survive. We had four offspring. The weaker offspring will sometimes be eaten by leopards. So we had a lot to make sure some survive. At max we can have seven offspring at a time.
  • Step 2: Genetic Variation
  • Only two of our offspring survived. Different traits of them are size(big or small), Fur(as camouflage and to keep warm), Teeth and jaw(size/sharpness), Legs and claws(size/sharpness), and eyesight(to hunt).
  • Step 3: Selection
  • Now we have to feed our cubs. The most important trait is the fur. Our fur is useful throughout our entire life. It is used to stay warm. Most important of all is to use it as camouflage. When we are little we can hide from leopards. Once we are grown it is used to hunt. It makes it very difficult for any prey to see us when we are sneaking up on them.
  • Step 4: Adaptation
  • Now it's time to show them how to hunt. Some other adaptations are our vision and our teeth/claws. Our vision is used when hunting. Our eyes allow us to see in the dark. This means we can hunt for food at night. Our claws/teeth are used for hunting as well. We are very easily able to tear apart and eat our food. Without these we wouldn't get food as well therefore we would die out.
  • Conclusion
  • Now that we have raised our cubs I think it is time to say goodbye. Now that they are leaving I think it is time to do it again.
  • Goodbye
