Abiogenesis, the development of living things from non living matter, is not something we know much about, since it happened about 4 billion of years before we were around and haven't reproduced it in the lab. My guess is that it's not easy. However, the Miller-Urey experiment and others have told us something about abiogenic production of organic compounds. ...

Abiogenisis, where imperfect micelles (spheres) of hydrophobic carbon chain formatiions leads to potentials for capturing and mixing elements and molecules forming peptides, polypeptides and protiens that can then catalyze enzymes to patterns to the micelle to a cell of sorts. Was it inside a terrestrial micelle that life formed or Did amazing spiraling ...

There are two questions here: Why does life only generate life? Why doesn't life continue to be generated on Earth? The first one is easy. We don't only generate life. If that were true, it might be illegal to flush toilets. Life forms of some kind would occupy all the space in our atmosphere. Babies - or some living things - would rise up from our ...

After considering this question some more, I think a key feature for this hypothesis to work is that the original function must be so integrated and vital for the biology of the organism that it must be mimicked/echoed to some extent. In terms of your RNA-example, it was not enought to evolve the ability to synthesize any complex molecule that could function ...

See this more as a comment than an answer, since it became too long for a comment. However, I think some of the examples should be relevant to refine your question. One thing that I find vague in this question is what exactly constitutes a "process"/"function"? To me, this can be almost anything. You seem to be focusing on molecular biology and biological ...

The E. coli long term evolution experiment showed that E. coli had evolved a function (the metabolism of citrate) which was not required in the ancestral environment, but which evolved naturally and was selected for in this new artificial environment. AFAIK, this is the only example of a function that has been observed naturally evolving under controlled ...

It was getting long for a comment: A species that was originally parasitic, but then evolved to survive independently of its host by independently evolving the same metabolic functions A predator that originally relied on its prey to synthesise some vital metabolite, but later evolved the ability to produce the missing metabolite for ...
