Its genetic code is roughly twice the size of the record-holding Megavirus. And it seems almost completely unlike anything else on the planet. Only 6 percent of its genes resembled the genes other organisms. Claverie says he thinks the Pandoraviruses may come from a different origin – perhaps radically different. "We believe that those new Pandoraviruses have emerged from a new ancestral cellular type that no longer exists," he says. That life could have even come from another planet, like Mars. "At this point we cannot actually disprove or disregard this type of extreme scenario," he says.
