    Sheep need retroviruses for reproduction.

    These (endogenous) sheep retroviruses help their placenta to develop.

    Thought this was interesting in light of the fact that XMRV proliferates in humans in androgen and other sex hormone environments (according to recent US research).

    Interesting how retroviruses have become helpful to some mammals in certain instances.

    Great find, pictureofhealth! I like sciencedaily.com very much for its clear writing about science topics. Anyway, they write here:

    "Studies in cultured cells have shown that a protein of a human endogenous retrovirus might have a role in development of the human placenta."

    I had read that elsewhere, that some retroviruses, long held in our DNA, play a constructive role.

    Retroviruses are everywhere.

    I feel sorry for those creatures with ERVs though - Koalas, Mice etc.

    What I find most interesting about this article is that retroviruses were beneficial for sheep, rather than damaging. I think I was operating under the assumption that Retrovirus = Bad, whereas this is not the case here and in fact they are life promoting!
