Understanding the principle of how the Earth could become a rare planet of life has been one of the biggest and fundamental subjects of Liberal Arts, as crystals of intellectual curiosity for human beings. If we could solve this mystery, even a piece, it will open a major breakthrough leading to find the possibility of life in the Universe, including the Solar System, as well as their conditions to exist.
What we already know of is that the interactive system between Earth and Life had occurred at the moment of the Earthfs birth and played a primary role in the co-evolution. The mantle, crust, ocean, continent, atmosphere, and all organisms that inhabit them, have all developed, functioned and evolved as a whole interactive system entity.
The primary evolution of the primitive Earth-Life system is the history of dramatic interactions, where the metabolic system, or the energy acquisition system took place, which supported changes and lives of primitive Earthfs environment. In conventional Earth Science researches, they usually turned the spotlight on Earth-Life interactive system of the past six hundred million years, which is provable by visible geological records and fossils, such as of Cambrian Explosion and mass extinction. And this is the period of time when the multicellular organisms appeared on this planet and is called Phanerozoic eon. However, the major mechanisms of Earth-Life interactive systems seem to have been already established long before six hundred million years ago from today, which is called Precambrian age.
The evolution of these mechanisms should be the major cause of how the Earth could become the rare planet of life, and this evolution should be called gPrecambrian Explosionh; the remarkable event in earthfs history.
The purpose of Precambrian Ecosystem Laboratory is to elucidate this Precambrian Explosion: the primary evolution of primitive, Earth-Life interactive systems. Our project goal is to get a larger, if not whole, picture of how the Ultra-H3 linkage, began at the limited areas in the ocean, evolved and propagated to planet-scale ocean environment, by going through the process of photosynthesis development and diversification of energy metabolisms. It is our mission to connect the history of Precambrian and Cambrian eons.
