  • Giraffes and Natural Selection
  • Overproduction of Offspring
  • Variation of the Population
  • In the safari of Africa there was an  perfect, open spaces for species to begin. Throughout the safari and the story the giraffes are going to change and adapted and only some will survive. 
  • Adaptions 
  • The giraffes produced lots of offspring and the offspring then make more offspring and so on. This is in hopes that most of the giraffes will survive to create a growing population.
  • Inherited Characteristics 
  • The new population of giraffes varied in size. Some of the giraffes had long necks that could touch the sky. Other giraffes had short necks. Both variations of the giraffe lived together for a little bit.
  • The Constantly Changing Safari
  • Sadly the giraffes with the small necks died out. There was not enough plants on the ground to sustain them with there short necks and they were unable to adapt. The giraffes with the long necks survived because they could easily reach the top of the trees. The long neck giraffes went from tree to tree eating. 
  • The safari was still filled giraffes, but the safari looked different than it did before. Before there were giraffes with long and short necks, but now there is only giraffes who have long necks.  The giraffes being born today have long neck; long necks is now an inherited characteristic and now apart of the gene pool. The long neck giraffes will live a good life for a couple million of years.
  • The safari became full of long necked giraffes eating all the trees they could. The safari went from giraffes of all sizes to tall giraffes only. The tall giraffes survived, but they are now faced with a new problem of changing weather. Since the Earth is constantly changing they will have to adapt and change there way or they will not survive.
