Natural Selection in Giraffes

Storyboard Text

  • A long time ago, giraffes with long and short necks lived with each other. They like to eat leaves and twigs from trees.
  • As the shorter trees began to disappear, only the giraffes with long necks could reach the tall trees. Since the trees are hard to reach for other animals and short-necked giraffes, the long-necked giraffes have less competition.
  • The giraffes with longer necks have the advantage, which meant that the giraffes with the shorter necks began to disappear.
  • Overtime, the giraffes with long necks reproduce offspring that will also have long necks. These are the giraffes we see living today.
