It is believed that all organisms have arisen from a single distant ancestor. The strongest evidence for this would be:

1. DNA stores genetic information in all organisms.
2. The genetic code is universally a triplet code.
3. The amino acids specified by particular triplets are almost always identical between any two organisms.
4. The genetic code is degenerate but unambiguous.
