Complex Creatures Thrive Deep Underground
South African gold mine reveals worms buried for 10,000 years
Now, a new study by a team, including Dr. Barbara Sherwood-Lollar, a geochemist in the Department of Earth Sciences at the University of Toronto, has found that even more complex organisms can survive, sealed up deep underground. They found nematode worms and other multicellular organisms in a South African gold mine, more than 1.4 km deep.
The organisms had been carried deep into the Earth in water that percolated underground through cracks and fissures, more that ten thousand years ago, and had survived ever since, sealed up in the deep Earth.
