After the Earth had formed, the atmosphere was very different from the present one, and contained no free oxygen, but hydrogen and hydrogenated compounds such as methane and ammonia. Sunlight, rays and heat sources such as volcanoes and radioactive materials could have reacted these compounds, producing more complex ones, which dissolved with minerals in primitive oceans, would have given rise to colloidal drops rich in polymers - such as proteins and nucleic acids - and later to the first living beings. In these aggregates is transcendent the presence of a membrane that separates an inner content from an outside environment. Metabolism, growth and reproduction would have been developed after the probiote acquired the ability to absorb and incorporate molecules into its structure.
