Storyboard Text

  • Genetic Variation
  • I think i'm safe from that eagle, my skin color allows me to blend in.
  • I hope that eagle's eyesight is off, because he could totally see me
  • Poor green snake, he has no camouflage whatsoever
  • Overproduction and struggle to survive
  • Green snakes are the easiest to find! They can't hide or camouflage
  • Green snakes need to adapt to this gray cave or we will go extict!
  • Differential survival and reproduction
  • Us gray snakes will survive!
  • In this population of snakes, we see there are two types. The gray snakes, and the green snakes.
  • Changes in Gene Pool
  • Where did all the food go? Guess I have to find another cave
  • The snakes have lots of eggs, but only few survive to adulthood. The green snakes don't survive to reproduce and therefore being eaten by predators makes them prone to extinction.
  • Soon, the predators will kill off all the green snakes, leaving the gray snakes to reproduce and pass on those genes to the next generation.
  • The gray snakes survived due to being able to camouflage into the cave, the gene pool will change and have the gray fur trait to produce all gray mice.
