  • Inheritance: the process by which genetic information is passed on from parent to child.
  • Overproduction: each generation has more offspring than can be supported by the environment.
  • Differential Reproduction: comparing successful reproduction rates between groups in a given generation of a species—in other words, how many offspring each group of individuals is able to leave behind.
  • Survival of the fittest: the continued existence of organisms which are best adapted to their environment, with the extinction of others
  • Variation
  • Overproduction
  • Survival of the Fittest
  • There are white seals, and dark seals
  • Reproduction/ Inheritance
  • the limiting factors of my population are that the light seals stand out in the dark water for predators.
  • Adaption
  • Trait selected: BlueTrait selected against: WhiteType of adaptation: Physical Environmental change: Predator
  • Variation leads to differential survival in this situation because the light seals stand out to predators more than the dark seals do.
  • The dark seals blend in with the environment, and this led to the survival of the dark seals over the light colored ones.
