Target entity: Great Ordovician Biodiversification Event
Context triple: [Late Ordovician mass extinction, precededBy, Great Ordovician Biodiversification Event]
  • A. Great Ordovician Biodiversification Event chosen
    The Great Ordovician Biodiversification Event was a profound evolutionary radiation during the Ordovician Period that saw a dramatic increase in marine biodiversity and the establishment of many major animal groups in Paleozoic oceans.
  • B. Late Ordovician mass extinction
    The Late Ordovician mass extinction was one of Earth’s largest biodiversity crises, during which severe climate change and glaciation led to the rapid loss of a substantial portion of marine species.
  • C. Neoproterozoic Oxygenation Event
    The Neoproterozoic Oxygenation Event was a major rise in Earth’s atmospheric and oceanic oxygen levels during the Neoproterozoic Era, linked to profound climatic shifts and the emergence of complex multicellular life.
  • D. Phanerozoic mass extinctions
    Phanerozoic mass extinctions are the handful of catastrophic, globally disruptive biodiversity crises over the last ~540 million years that abruptly wiped out large proportions of Earth’s species and reshaped the course of evolution.
  • E. Cambrian explosion
    The Cambrian explosion was a relatively brief period around 541 million years ago when most major animal groups rapidly appeared in the fossil record, dramatically increasing the complexity and diversity of life on Earth.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
