example: MET and FET insufficient for MST

paraphrase

• Eukaryotic single-celled organisms appear in the fossil record by approx. 1.6 BYA (Knoll et al., 2006).
• Yet for a “boring billion” years of evolutionary history, they remain minor components in bacterial-dominated ecosystems
  • before explosively radiating as large, multicellular species in
    • an Ediacaran and
    • Cambrian MST.
• Eukaryotes are obviously essential for this MST, as all
  • animals,
  • plants and
  • fungi

• are eukaryotes.

• However, the initial appearance of eukaryotic cells seems insufficient for a MST
