WebDNA most likely did NOT develop to become a protocell. The protocell almost certainly came first, and used something else as its genetic material. Eventually, either from the beginning or evolving from an even older precursor, the genetic material became RNA. WebProtocells. Now, I found a claim from someone on the r/DebateAnAtheist and he said those two statements below which are links to some papers. That protecells can spontaneously form in solutions. That these spontaneously forming protecells can replicate and grow naturally. Now I did a little digging and found that this website said that no ...
