  • The Giant viruses dating back 1.5 billion years were found in Yellowstone's geothermal springs.
  • The viruses are labelled as 'giant' because they have extremely large genomes compared to regular viruses and pose no risk to humans.
  • But it could explain what the conditions on Earth were like when single-cell organisms formed.
  • Yellowstone's hot springs formed at least 15,000 years ago after the last glaciers in the region melted, allowing the geysers to spring up.
  • The Yellowstone National Park of USA is the first national park in the world, which was opened in 1872.
