→Shared endogenous retroviruses: HTTP --> HTTPS #3, replaced: http://www.ncbi.nlm.nih.gov → https://www.ncbi.nlm.nih.gov (2)
A [[Retrovirus]] is a virus that incorporates itself into an host cell's DNA, and programs the host cell to produce copies of the virus. [[Endogenous retrovirus]]es (ERVs) are retroviruses that infected an organism's [[germ cell]]s, and were thus passed to the next generation, and incorporated into the organism's genetic line over time.

Researchers estimate that 1% of the human genome is occupied by ERVs, constituting approximately 30,000 different ERVs.<ref>Sverdlov, E. D. (2000) "Retroviruses and primate evolution."

From these facts, evolutionists argue that these ERVs are shared by humans and primates because they were inherited by a common ancestor.
