The nuclear genome of eukaryotes comprising the genes from both the Bacteria and Achaeans supports the position of eukaryotes at the convergence of the ring of life.
The genomes incorporate within them the data of the evolution of life on Earth. It has been shown that the eukaryotic genome originated from an amalgamation of two different prokaryotic genomes, and thus, at the deepest levels associating both the eukaryotes and prokaryotes and therefore, one can say that the tree of life is in a real sense a ring of life.
One of the partners taking part in the process of fusion branches from deep within an ancient photosynthetic clade and the other is associated with the Archaeal prokaryotes.
