Comment: HERVs are ancestral (Score 2, Informative) 478

The posted summary is somewhat misleading. Human endogenous retroviruses (HERVs) are responsible for ~8% of the human genome sequence, but these things haven't been active for a long time in terms of human history - so the 8% that's in your genome now did come from your parents, and their parents etc. until you get back to the time many thousands of years ago when HERVs were actively creating new insertions. The linked summary is a summary of a new finding in which the 'endogenization' of a new class of virus known as a Bornavirus is reported (which exists in only a few copies in humans)
