Here is a new take on the origins of life, which postulates a much earlier, and from diverse locations of the combination of elements floating around the universe just waiting for suitable worlds to evolve – Deskarati
Life originated in a nebular cloud, over 10 billion years ago, but may have had multiple origins in multiple locations, including in galaxies older than the Milky Way according to Rudolf Schild of Harvard-Smithsonian Center for Astrophysics and Rhawn Joseph of the Brain Research Laboratory. Multiple origins, they believe, could account for the different domains of life: archae, bacteria, eukaryotes.
The first steps toward life may have been achieved when self-replicating nano-particles initially comprised of a mixture of carbon, calcium, oxygen, hydrogen, phosphorus, sugars, and other elements and gasses were combined and radiated, forming a nucleus around which a lipid-like permeable membrane was established, and within which DNA-bases were laddered together with phosphates and sugars; a process which may have taken billions of years.
DNA-based life, they propose, may be a “cosmic imperative” such that life can only achieve life upon acquiring a DNA genome. Alternatively, the “Universal Genetic Code” may have won out over inferior codes through natural selection. When the first microbe evolved, it immediately began multiplying and spreading throughout the cosmos via panspermia carried by solar winds, Bolide impact, comets, ejection of living planets prior to supernova which are then captured by a newly forming solar system, galactic collisions and following the exchange of stars between galaxies.
