Is it possible that life originated multiple times on earth? The way you describe it, you make it sound so easya. It's a long distance to go from the first bit of prebiotic chemistry to, say, molecular machines like ribosomes. As soon as we introduce even random bits of information into into there,. I'm thinking about orona molecules, for example. Doesn't have to have any information. But if it's introduced into a system which is in any case, growing and doubling itself and reproducing itself then any changes in that sequence that allow it to do so better or worse are now selected by perfectly normal natural selection with the system.
