The Origin of Life: the Evolution of Viruses, the Simplest Bacteria and the Last Universal DNA Molecule

Abstract

Since viruses are the first form of life on Earth, it can be shown that it was viruses that formed and spread biological life on the planet. The evolutionary transition from giant viruses to the first protozoan bacteria is logical and can be considered proven. The genome of the organism is encoded in DNA and viruses are the first form of life, therefore, in the past, there should have been the last universal DNA molecule, which contained the genes of all possible living beings in our biosphere.
