A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic "junk", may actually play powerful roles in regulating gene expression. Focusing ...

Ancient viruses left a legacy in your DNA. And it turns out, that legacy may be helping shape who you are. A recent international study has shown that certain bits of ancient viral DNA, long dismissed ...

(CNN) — The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient ...

Around 8% of the human genome is made up of ancient viral sequences—endogenous retroviruses (ERVs) that integrated into our ancestors’ germline millions of years ago. Once thought to be inert genetic ...

Add Yahoo as a preferred source to see more of our stories on Google. HERVs, or human endogenous retroviruses, make up around 8% of the human genome, left behind as a result of infections that ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...
