Question

How does a universal genetic code relate to the hypotheses about the origin of life on Earth?

Answer 1

all organisms on Earth have one genetic code (except
mitochondrias that
probably changed it for some reasons).& In fact,
universal genetic code is
fundamental evidence that all organisms
(viruses, bacterias, eucariotes)
evolved from one common ancestor,
because otherwise organisms should have
different genetic codes.
Furthermore, according to hypothesis of RNA world,
all modern organisms
came from one ancestor that was composed only from
nucleic acids. This
ancestor had RNA as a carrier of genetic information,
and used same
genetic code as now-living organisms.
