100 million years old microbe are still alive in the most uninhabitable places like beneath the surface of sea floor. When those microbe brought back to lab and fed they start multiplying. Microbes live on oxygen somehow exist on what little of the gas diffuses from the deep ocean surface.
Microbes often find a way to survive. Life can survive in place biologist once thought uninhabitable. If life survive beneath the ocean bed it might be possible that life will be sustaining elsewhere in the universe. If the surface of the planet does not look promising for life it may be holding life out the subsurface. Microbes are known to live very hot or toxic environment. They can also live in place where there is very little food. To find out some scientist mounted a drilling expedition in the South Pacific Gyre, a site of intersecting ocean currents east of Australia that is considered the deadest part of the world’s oceans, almost completely lacking the nutrients needed for survival. When they extracted cores of clay and other sediments from as deep as 5700 meters below sea level, they confirmed the samples did indeed contain some oxygen, a sign that there was very little organic material for bacteria to eat.
