Retroviral infection results in a provirus integration into the host genome. An infection of a germline cell could lead to the provirus potentially being inherited by the offspring of the infected individual. Once in the genome, the provirus becomes subject to evolutionary processes and can become either lost or fixed in a population, remaining as “fossils” long after the exogenous retrovirus has gone extinct23. Notably, 8% of the human genome consists of ERVs30. Human Endogenous Retrovirus Type K (HERV-K)(HML-2) family is of particular interest. HERV-K integrations are as old as 30-35 million years, endogenizing before the separation of humans and Old World Monkeys.
