Life Origin on Earth, Knowledge Development

Abstract

An enigmatic and important feature of life origin on Earth is embodied with a number of different hypotheses and knowledge based on experimental data and biomedical principles. These hypotheses and understanding generally contain some small-scale experimental simulation, chemical structure comparisons and a series of guesswork from existing biological knowledge and principles. So far, there is no widely agreement of single hypothesis without significant arguments and conflicts between researchers of different disciplines and individual biological characters. Thus, it needs more heated debates, cooperation and circulation for life origin topics academically and in large media to all human population. These debates and publication may invite interests of non-academic careers and solve this enigma from widest human professions.
