Progenotes
Progenotes both composed FUCA and descended from FUCA. FUCA is thought to have organized the transition from initial biological systems to mature progenotes. Progenotes were the dominant forms during the Progenote age, when biological systems first originated and assembled. The Progenote age would have happened after the pre-biotic RNA-world and Peptide-world ages, but before the emergence and presence of organisms and mature biological systems like viruses, bacteria and archaea.
