What Conditions Does Life Need?

  • Exhibition Text

    • LIFE as we know it REQUIRES:

      Life on Earth’s surface derives its energy from the Sun. Another realm of life thrives around seafloor hot springs and in fluid-filled cracks deep below the surface, utilizing the chemical energy of those environments. The chemistry that builds and sustains life requires a fluid medium in which atoms and molecules can react. For all known forms of life, liquid water provides that environment. Carbon atoms are ideally suited to form complex molecules. Carbon is the structural backbone of all the building blocks and material for life, including proteins and DNA.
