Project: Discovery of Living Microorganisms Inside 2 Billion Year Old Rocks

The University of Tokyo has released the results of the Astrobiology Center’s Call for Projects (Proposal No. AB0606)!

A microbial paradise that has lasted for 2 billion years (from University of Tokyo press release)
Presentation Points
  • A team has succeeded in collecting living microorganisms from a 2-billion-year-old stratum beneath South Africa.
  • This is an achievement that takes the record of the oldest strata in which living microorganisms have been found all the way back from 100 million years ago to 2 billion years ago.
  • If microorganisms have not evolved inside stable rocks for 2 billion years, it is expected to provide insight into the origin and early evolution of life on Earth.
