Turtle process of natural selection by Gianna Mazur

Turtle process of natural selection by Gianna Mazur

Storyboard Text

  • Overproduction
  • Variation
  • Environment
  • Sea Turtles produce more offspring than that will survive. Some may not make it to adulthood because of being eaten, not having enough food, etc.
  • Struggle
  • The variation of the Sea Turtles is hard and soft shells. One variation will be selected by nature and one will be selected against in the process called natural selection.
  • Selection
  • The Sea Turtles preditor are sharks, which are in the same environment as the Sea Turtles. Sharks will hunt these turtles so, the turtles will see them as a threat.
  • Differential Reproduction
  • These Sea Turtles are always in a never-ending competition to get food, shelter, mates, to not get eaten, etc.
  • The variations are selected for and against through the natural selection process. Organisms with help with adaptation like, hard-shell turtles which are more likely to survive. The hard shell allows them to protect themselves, unlike the soft turtle shells.
  • Over many years, evolution and natural selection occur and they work together to form a population of successful Sea Turtles. Since nature selected against the soft shell turtles, there will be few to no turtles with the soft shells, and they will eventually die out.
