Human genome has about 100, 000 known fragments of wiral genetic material - about 8%.
Ancient wiruses that housed into our DNA, millions of years ago, may be our puppetmasters.
"We are creatures controlled by wiruses," says Luis Villarreal, evolution scientist, University of California. His team showed that a viral gene is needed for formation of placenta.
"Genes borrowed from viruses give cells ability to grow into tissues and organs. Without these, animal life may have remained, to blobs of cells," says another New Scientist article.
Jan Carette, a Stanford virologist says, "We would not exist without viruses."
