On first glance it seems that this worm was brought back to life with scientific intervention exclusively. But with the disappearence of permafrost these worms will thaw on their own and will resume living and procreating. What I want to say is, that many species of these ice-aged worms may be alive already without anyone noticing, trough permafrost has been thawed away. Who knows what impact these worms will have on our recent fauna and flora?
