Transition 1 : Evolution of Cells (ie. LUCA, LBCA, LACA) and Viruses
Current biochemical theories for the evolution of Cells and Viruses need to be made congruent with the timing of the astrophysical evolution of molecular clouds, proplyds, stars and planets.
Molecular species at different time points can be graphed in a pathway towards the origin of Ancient Viruses and Cells (ie. LUCA).
Methylthioacetate are the early building blocks that combined with energy from light and radioactivity to emerge into FUCA (First Universal Cellular Ancestor) and Viruses.
Theory 1 : LUCA was a progenote/protocell without a complete universal genetic code that generated LACA and LBCA from separate progenote pathways.
Theory 2 : LUCA was DNA based and the direct ancestor of LACA and LABA .
Theory 3 : LUCA evolved into LABA and then LABA via planctomycetes into LACA.
Four pre-LUCA stages associated with the evolution of the universal genetic code include:
1. Vesicle stage : Polymerizations + self-assembly of metalpeptides ( ie.Hemolithin ) and Polycyclic Aromatic Hydrocarbons formed ProCellular Vesicles during the protoplanetary stage of life. Protoplanetary objects like Ganymede, Enceladus, Europa, and Ceres may contain examples of Procellular Vesicles within Ocean-Mud Worlds. Pre-ribosomal protein synthesis via aminonitrile reactions and cysteine catalyzed peptide ligation.
2. Procell to Early Protocell stage:
a. Evolution of the proto-tRNA replicators within Procells on planetismals rotating in front of the young Sun and creating a heating / cooling cycle about every 40 minutes.
4. Late Protocell/Progenote Stage : Protocell Consortia transitioned into LUCA or LBCA + LACA during Planetary Formation and after the Theia + Proto Earth Collision.
