Storyboard Text

  • A group of giraffes live in the savannas of Africa where they roam freely among the open plains. 
  • Some giraffes had long necks while others had short necks.
  • Minerals within the ground went around and infected all the bushes, so eventually all the infected bushes died off.
  • With the short neck giraffes not being able to reach the tall trees some started to die off while others were effected by the minerals.
  • The only mutation the minerals had on the short neck giraffes was growth. The short neck giraffes affected grew a long neck and longer legs.
  • After generations and generations there were no more short neck giraffes.
