Page "Common descent" Paragraph 11

All known forms of life are based on the same fundamental biochemical organisation: genetic information encoded in DNA, transcribed into RNA, through the effect of protein-and RNA-enzymes, then translated into proteins by ( highly similar ) ribosomes, with ATP, NADH and others as energy sources, etc.

Furthermore, the genetic code ( the " translation table " according to which DNA information is translated into proteins ) is nearly identical for all known lifeforms, from bacteria to humans.

The universality of this code is generally regarded by biologists as definitive evidence in favor of the theory of universal common descent.

Analysis of the small differences in the genetic code has also provided support for universal common descent.

A statistical comparison of various alternative hypotheses has shown that universal common ancestry is significantly more probable than models involving multiple origins.
