The core life elements (H), C, O, N were produced by the first generation of stars. A rocky planet surface is almost all just silica on the other hand.
- adastra22 4y agoI don't think that post is very interesting from an origin of life perspective. The factors which limit genome growth would not have been in play at the origin of life. If the RNA origin theory of life is correct, then our oldest ancestors were replicating pieces of RNA in some sort of primordial soup. In that environment there would have been pieces of RNA everywhere whizzing about, combing, recombining, and replicating. There would have been explosive growth in "genome" size in very short amount of time, because changes would be spontaneously happening without the need for slow cycles of mutation and natural selection, which would come to dominate later.
