Fig. 1From: Emergence of life: Physical chemistry changes the paradigmEarth’s physicochemical evolution from 4.5 bya (billion years ago): the continuity of chemistry and biology. Earth’s chemistry evolved in atmosphere, hydrosphere and lithosphere with rampant phase separations of microspaces (0.1 - 1000 μm) driven by diurnal cycles of solar radiation, temperature and water activityBack to article page
