@gwern @cinnamon_carter P atoms in universe limit random trials of RNA at 1e6/second in parallel to << 10^92 in 10e10 yrs.

@gwern@cinnamon_carter It's not a niche if no organism has chemical ability to exploit it.
@gwern @cinnamon_carter Niches that required photosynthesis, nitrogen fixing, and even many far simpler capabilities were unavailable.

@NickSzabo4@cinnamon_carter Nevertheless, early Earth would have a great variety of organic chemicals to harvest. That is a big opportunity -
@gwern@cinnamon_carter What kinds of organics? What 150 base pair ecosystem could exploit them? Be specific stop hand-waving. -
@NickSzabo4@cinnamon_carter It would use the amino acids and nuclear acids floating around, you know that. The usual abiogenesis proposals. -
@gwern@cinnamon_carter A 150 base pair ecosystem can't catch, much less put to use, most of the amino & nuclear acids floating around. -
@NickSzabo4@cinnamon_carter Why does it need to catch to grow or spread or evolve w/o competition? Does not catching prove panspermia? -
@gwern@cinnamon_carter Many far more likely places in universe to find stable amino+nucleic acid soup than bombardment-era Earth. -
@NickSzabo4@cinnamon_carter Be that as it may, what does that have to do with linearity of genomes as clocks and that paper's model? -
@gwern@cinnamon_carter Linearity is just a good initial way to avoid "and now a miracle occurred" assumptions that plague these debates. - 16 more replies
