How did life begin? How did chemical reactions on the early Earth create complex, self-replicating structures that developed into living things as we know them? According to one school of thought, before the current era of DNA-based life, there was a...
Depends. You’d have to have the right soup, and the right environmental conditions to make the the relevant reactions probable.
If those conditions exist currently, those proto-life fragments would probably need to be in niches devoid of life, as they wouldn’t be able to compete/survive with DNA based lifeforms around.
