- Reposted by Lauren QueissArchaea may not be well known, nor well studied, but these microorganisms can live in the most extreme environments, but also right on our skin. They’re everywhere. EMBL researchers are now exploring their unique ecosystem adaptability and link to evolution. www.embl.org/news/science...
