The human endogenous retrovirus K (HERV-K) was inherited million years ago by the genome of the human ancestors. [18] In 1999 Barbulescu, et al. showed that, of ten HERV-K proviruses cloned, eight were unique to humans, while one was shared with chimpanzees and bonobos , and one with chimpanzees, bonobos and gorillas . [ 19 ]
For example, viruses can cause evolution of their hosts, and the signatures of that evolution can be found and interpreted in the present day. [2] Also, some viral genetic fragments which were integrated into germline cells of an ancient organism have been passed down to our time as viral fossils , [ 2 ] or endogenous viral elements (EVEs).

Endogenosymbiosis is an evolutionary process, proposed by the evolutionary and environmental biologist Roberto Cazzolla Gatti, in which "gene carriers" (viruses, retroviruses and bacteriophages) and symbiotic prokaryotic cells (bacteria or archaea) could share parts or all of their genomes in an endogenous symbiotic relationship with their hosts.

A retrovirus is a type of virus that inserts a DNA copy of its RNA genome into the DNA of a host cell that it invades, thus changing the genome of that cell. [2] After invading a host cell's cytoplasm, the virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro (backward).
Human Endogenous Retrovirus-W (HERV-W) is a family of Human Endogenous Retroviruses (HERVs). HERVs are part of a superfamily of repetitive and transposable elements . Transposable elements are sequences of DNA that can move or "jump" around the genome, sometimes replicating and inserting themselves in different locations.
