ERV-Fc
endogenous retrovirus
ERV-Fc was an endogenous retrovirus (ERV), or a genus or family of them, related to the modern murine leukemia virus. It was active and infectious among many species of mammals in several orders, jumping species more than 20 times between about 33 million and about 15 million years ago, in the Oligocene and early Miocene, in all large areas of the world except for Australia and Antarctica. After about 15 million years ago, it became extinct as an active infectious virus, perhaps due to its hosts developing inherited resistance to it, but inactive damaged copies and partial copies and fragments of its DNA survive as inclusions in the hereditary nuclear DNA of many species of mammals, some in different orders, including humans and other great apes. That has let interspecies jump routes of the spreading virus be tracked, and timed by the molecular clock in their extant descendants, but with gaps where trails were lost by passing through infected animals who left no extant descendants or by loss of the integrated sequence in some lineages.

This brief starts where responsible research should: with the source description of “ERV-Fc” as endogenous retrovirus. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as endogenous retrovirus. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 10, 2025. The linked authority identifier is Q105473832. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
