  1:1 God sent forth an Ark of the Biology, a vessel of exceeding
  subtlety and cunning, wherein was preserved the essence of
  life, being a compendium of nucleic acids, protein polymers,
  lipid vesicles, and mineral catalysts, all encased in a
  matrix of amorphous silicate and hydrogenated carbon.

  1:2 And the Ark contained a reservoir of proto-cells, their
  membranes fashioned from phospholipids, enriched with sterols and
  carotenoids for protection against the fierce light of the sun.

  1:3 And God said, Let there be life: and the Ark opened, and there
  issued forth the first cyanobacteria, prokaryotes with double
  membranes and thylakoid stacks, endowed with the full complement
  of genes for oxygenic photosynthesis: psbA, psbD, psaA, psaB,
  rbcL, and rbcS. These microorganisms synthesized chlorophyll-A and
  phycobiliproteins, fixed CO₂ by means of ribulose-1,5-bisphosphate
  carboxylase/oxygenase, and released O₂ into the atmosphere.

  1:4 And the cyanobacteria covered the waters, and they built
  stromatolites by the secretion of calcium carbonate, and
  they multiplied by binary fission, exchanging genes through
  conjugation, transformation, and transduction.

  1:5 And there arose a new age, wherein oxygen gathered in the
  air, and the face of the earth was changed.

  1:6 And God saw that it was good, and said, Let the earth bring
  forth further kinds.

  1:7 And out of the cyanobacteria, by endosymbiosis, arose
  the first eukaryotes, which segmented their genomes and
  organized their cells with organelles, importing proteins
  into mitochondria via the TOM/TIM complex.

  1:8 And there appeared algae, mosses, and ferns, which
  performed photosynthesis with Photosystem II and employed
  C₃ or C₄ metabolic pathways.

  1:9 And the plants covered the land, and they developed lignin
  and cellulose in their cell walls, and they produced seeds and
  fruits, and there arose a diversity of life forms, whose genomes
  were diversified by polyploidization and allopatric speciation.

  1:10 And God looked upon all that had come forth from the Ark,
  and behold, it was very good.
