This new evidence of Archaea having epigenetics indicates that it is not as relatively ‘new’ thing to the Earth. It also raises the question whether the shared common ancestor of Archaea and Eukaryotes had this mechanism, or did each evolve epigenetics independently through coevolution. This also raises the question if epigenetics is the reason why no known archaea cause disease or are antibiotic like bacteria. This finding could accelerate the study of epigenetics in Humans. The differentiation of eukaryotic cells and the occurrences of cancer makes it difficult to study in eukaryotes, but the simplicity of archaea and the structural similarity to eukaryotes make it easier to study. Using archaea to study epigenetics is also faster and cheaper. This may finally help scientists determine how to reverse epigenetics and learn how to switch it on and off.
