  • Vast amounts of debris, soot, and aerosols shot into the atmosphere when an asteroid slammed into Earth 66 million years ago, plunging the planet into darkness, cooling the climate, and acidifying the oceans.
  • Along with the dinosaurs on the land and giant reptiles in the ocean, the dominant species of marine algae were instantly wiped out — except for one rare type.
  • Only much later did the algae evolve, losing the ability to eat other creatures and re-establishing themselves to become one of the dominant species of algae in today’s ocean.
