Hitting Rock Bottom
New study shows abundant life feeding on Earth's oceanic crust that may hold clues to origins of life
Once thought to be mostly barren, the ocean floor is teeming
with life, according to new research. Vast communities of
tiny bacteria and other microbes that have existed for more
than 3 billion years thrive on deep-sea rocks, yet
scientists, including those at Scripps Institution of
Oceanography at UC San Diego, are just beginning to
understand their self-sufficient lifestyle and link to early
life on Earth.
