Storyboard Text

  • Natural Selection of Blue Oysters 
  • We are very concerned about our well-being as a species.
  • Step 1: Overproduction of offspring
  • A new island! Time to populate .
  • Step 2: Variation
  • Y'all don't have the new shells? They are stronger and more elusive. 
  • We can't all be like you, JOHN. 
  • The Asian Shore Crab is approaching, time to leave!
  • Step 3: Selection
  • When the oysters migrate to an island without predators the first thing the oysters do is cover the island with their offspring. 
  • Step 4: Adaptation
  • Of course y'all just HAD to change colors on us like that
  • After only 15 years of being terrorized by the crabs, the oysters developed harder shells and a darker color to protect themselves. 
  • Happy Ever After
  • After most of the oysters breed and produce more elusive offspring the crabs pick off any remaining white crabs. 
  • BTW you suck at hide and seek bro
  • The oysters have now changed colors and texture to blend in with the water and surrounding rocks, fooling the impending doom.
