Because all cells are similar in nature, it is generally thought that all cells came from a common ancestor cell termed the last universal common ancestor (LUCA). 1. Examples include sac fungi, club fungi, yeasts, and molds. This is based on evidence now available from chemical analysis. Some of the evidence behind this hypothesis is based on a “superphylum” of bacteria called PVC, members of which share some characteristics with both archaea and eukaryotes.

The three-domain system is a biological classification introduced by Carl Woese et al. The Three Domain System, proposed by Woese and others, is an evolutionary model of phylogeny based on differences in the sequences of nucleotides in the cell’s ribosomal RNAs (rRNA), as well as the cell’s membrane lipid structure and its sensitivity to antibiotics.
