Few years back, it was so belived that spontaneous synthesis of complex RNA molecules was highly improbable.
Recently I've heard about some recent experiments which could possibly be the likely mechanism to natural RNA synthesis. Do these hypothesis substantially increase the likelihood of the natural RNA synthesis (although we might never come to know about exact mechanism that took place) or we are still far from anything significant?
