| I speculate that ProCells arose on Inner Ort comets, minor planets, mini Theias and ProtoEarth . They transformed into Precells after collisions OF Titan-like mini Theias and hydrophobic Late Heavy Bombardment period comets. The physiochemistry of Hadean Earth allowed Precells to evolve into Prokaryocytes (Archaea followed by Eubacteria). Subsequent infection of Prokaryocytes by NCLD Viruses created Eukaryocytes AROUND 2.0 billion years ago (AN EXAMPLE OF THE PRINCIPLE OF INFECTIOUS SPECIATION).The Archaea evolved from Methane producers while Eubacteria evolved from Acetate producers. Lipid membranes changed due to evolution in different redox, temperature, hydrophobic, and Cobalt concentration environments. However, transcription, translation , and the genetic code have a common inheritance. The first Eubacteria were CPR like cells that used Carbon Monoxide, Carbon Dioxide, and Hydrogen. The Autotrophs diversified into various electron donor and acceptor types (chemo-inorganic/litho, chemo-organic, and phototrophic). Subsequently, Heterotrophs evolved from Chemo-organic Autotrophs and created predation based ecosystems. Predation resulted in symbiotic events marked by turning points in evolution. ( Such as monoderm to diderm transitions, evolution of cyanobacteria, and viral endosymbiotic events.) Archaic Heterotrophs subsequently evolved into Proterozoic Autotrophs through DNA transpositions and secondary/ tertiary symbiotic events. Prokaryotic evolution was impacted by bacteriophage based elements and prokaryote-prokaryote symbioses.
Mobile genetic elements were responsible for the origin and evolution of higher complexity. Natural Selection from temperature, humidity, and radiation fluctuations interacted with mobile genetic element based radiations to evolve new elements and cells. The Archaic time period was marked by dramatic changes in the Methane, Sulfur-Sulfide-Sulfate, Oxygen, Carbon Monoxide-Dioxide, Nitrogen-Nitrate, and Metal (Mn, Zn, Fe, Co, Cu, Ca, Mg, Mo, Strontium, Tungsten, Ag, Au, Hg ) levels of the atmosphere and oceans. Prokaryotic evolution matches the earth’s historic mineral and gas patterns with the Microbiome at that time period. Examining the evolutionary presence of metabolic operons will assist model development. horizontal transfer of these operons is mediated by viral elements and potentially ORIGINATING from cosmic sources.
LACA Stands for the Last Archaeal Common ancestor is believed to be sister to LBCA (The Last bacterial common ancestor) and is a descendent of LUCA ( Last universal Common Ancestor). |
