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.
