Storyboard Description

A species of deer is overpopulated and has a variation of longer antlers allowing it to fight off its predators (wolves). The longer antler species survive to reproduce more allowing for them to become more common in the population.

Storyboard Text

  • Overpopulation
  • We must surpass our carrying capacity to increase our chance of survival against the wolves.
  • Variation
  • Run away! We are unable to fight them off!
  • Selection
  • Chance of survival:
  • Chance of reproduction:
  • Selection
  • This elk species with extremely small antlers is overpopulated. This is due to a massive increase of offspring, because of a surplus of food available within their environment. Their current population of 17 surpasses their current carrying capacity of 12, but they must produce more offspring to survive against their natural predators.
  • Chance of survival:
  • Chance of reproduction:
  • Adaptation
  • There was a multitude of mutations in the heritable "Antler Size Gene" within the DNA of some individuals in this elk population. This allowed some elk to grow longer antlers. This in return created a variation of antler sizes throughout the population.
  • This structural adaptation helps increase our chance of survival against those wolves.
  • 100 years later...
  • The natural predator of this elk species is the grey wolf. The elks with extremely small antlers are at a disadvantage because they are unable to fight off the grey wolves. This reduces their overall chances of survivability and reproduction of offspring significantly due to a simple process known as selection.
  • This long antler trait is now common throughout our population.
  •  We can finally maintain our population!
  • Adaptation/Result
  • On the other hand, the elk with the longer antlers are able to easily fight off and defend themselves from the grey wolves. This puts them at an advantage because their overall chances of survivability and reproduction of offspring are increased significantly due to a simple process known as selection.
  • Retreat! Their long antlers make them too strong!
  • The elk who grew longer antlers, due to mutations from the heritable "Antler Size Gene", have successfully adapted to their environment by harnessing their structural adaptation. Furthermore, this heritable structural adaptation allows for an increase in the chance of survival to themselves as well as their offspring and starts to become a more common trait throughout the population.
  • The heritable mutation of the"Antler Size Gene" has successfully passed down to generations. After 100 years, the elk have fully adapted to their environment, and the longer antler trait is common throughout the population allowing these elk to successfully grow and maintain their population. This was due to a cause of biodiversity known as "Natural Selection" which created a structural adaptation allowing this elk species to thrive in its environment.
