Proposing the Earth-Life interactive system gUltraH3 Linkage Hypothesish that supported the oldest ecosystem on Earth
We proposed the existence of "Ultramafics-Hydrothermalism-Hydrogenesis-HyperSLiME (UltraH3) linkage", assuming that the life was born in deep-sea hydrothermal fields and this linkage has spread to play the role of the very first and the sustainable ecosystem in deep-sea. We estimated that the HyperSliME has been existing only at the seabed hydrothermal fields until today where peridotite is exposed and Earth in its primitive condition is still represented. Furthermore, we brought forward a new theory for the first time that in Hadean eon (approximately four billion years ago from today), HyperSLiME seems to have generally existed in komatiite.
