Scientists have discovered an ‘Underground Galapagos,’ which could be a clue to the origins of life on the Earth.
Whether it is tiny worms found wriggling in the depths of a South African mine or micro-organisms discovered six kilometers (3.7 miles) under the surface in China, subterranean life forms are found everywhere.
“We are making incredible discoveries about the nature and distribution of deep microbial life,” said Robert Hazen, executive director of the Carnegie Institution’s Deep Carbon Observatory geophysical laboratory…
“It’s an intriguing part of evolution,” said John Baross, a professor at the University of Washington in Seattle.
“The deep sub-surface may have acted as a natural laboratory for the origin of life in which multiple experiments could have been carried out in tandem,” he said.
“You have everything you need to make life including energy, water and carbon-rich molecules that could have made the underground rather than the surface of the planet, the cradle of the very first life on earth.
“We may find totally new kinds of life as we reach greater depths, higher temperatures and pressures. Quite possibly Earth’s deepest life doesn’t use DNA and proteins the way normal cells do.” Source
