Six hundred million years ago, the fossil record displays the sudden appearance of
intracellular detail and the 32 phyla. The “Cambrian Explosion” marks the onset of dominant
aerobic life. Fossil intracellular structures are so similar to extant organisms that they were
likely made with similar membrane lipids and proteins, which together provided for
organisation and specialisation. While amino acids could be synthesised over 4 billion years
ago, only oxidative metabolism allows for the synthesis of highly unsaturated fatty acids, thus …
