Final answer:

During the Late Precambrian era, Earth experienced significant changes including glaciations, climatic shifts, and evolutionary impacts that set the stage for the Cambrian explosion.


Explanation:

The Late Precambrian period witnessed significant alterations in Earth's subsystems:

  • Geologic Changes: The Earth underwent glaciations covering large parts, leading to the 'Snowball Earth' phenomenon.
  • Climatic Changes: Dramatic shifts occurred with the introduction of oxygen and the formation of a protective ozone layer.
  • Evolutionary Impact: The subsequent melting due to global warming opened up new ecological niches, possibly driving the explosive evolution seen in the Cambrian explosion.
