Phrase: Cambrian explosion | Statement: [Evolving Planet, hasSection, Cambrian explosion]

Target entity: Cambrian explosion
Context triple: [Evolving Planet, hasSection, Cambrian explosion]

• A. Ediacaran biota
  The Ediacaran biota comprises some of the earliest known complex multicellular organisms, featuring soft-bodied, enigmatic life forms that lived in the oceans before the Cambrian explosion.
• B. Permian–Triassic mass extinction
  The Permian–Triassic mass extinction was the most severe biodiversity crisis in Earth's history, wiping out the majority of marine and terrestrial species around 252 million years ago and marking the boundary between the Paleozoic and Mesozoic eras.
• C. Phanerozoic Eon
  The Phanerozoic Eon is the current and most recent major division of Earth's history, marked by abundant fossil evidence and the evolution and diversification of complex life forms, including plants, animals, and eventually humans.
• D. Neoproterozoic Era
  The Neoproterozoic Era was the final era of the Proterozoic Eon, marked by global “Snowball Earth” glaciations and the emergence of early multicellular life leading up to the Cambrian explosion.
• E. Cretaceous–Paleogene boundary
  The Cretaceous–Paleogene boundary marks the geological transition 66 million years ago associated with a mass extinction event that wiped out non-avian dinosaurs and many other species, likely triggered by a large asteroid impact.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Cambrian explosion
Triple: [Evolving Planet, hasSection, 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.
