A science class uses a simplified geologic time framework to organize Earth's long-term history by order and relative duration (not exact dates). The timeline is divided into three segments whose drawn lengths are not equal, to emphasize that Earth's history is vast:
  • Segment 1: Early Earth history (longest segment)
  • Segment 2: Middle Earth history (medium segment)
  • Segment 3: Recent Earth history (shortest segment)
Three events are placed in order from left to right on the timeline: (A) first oceans form, (B) many kinds of animals become common in oceans, (C) humans appear. Based on this framework, which event happened latest in Earth's history?
