Evidence of ancient life discovered in mantle rocks deep below the seafloor — ScienceDaily

Ancient rocks harbored microbial life deep below the seafloor, reports scientists. This first-time evidence was contained in drilled rock samples of Earth’s mantle — thrust by tectonic forces to the seafloor during the Early Cretaceous period. The discovery confirms a long-standing hypothesis that interactions between mantle rocks and seawater can create potential for life even . . . → Read More: Evidence of ancient life discovered in mantle rocks deep below the seafloor — ScienceDaily

Oxygen oasis in Antarctic lake reflects Earth in distant past — ScienceDaily

At the bottom of a frigid Antarctic lake, a thin layer of green slime is generating a little oasis of oxygen, a team of researchers has found. It’s the first modern replica discovered of conditions on Earth two and a half billion years ago, before oxygen became common in the atmosphere.

Oldest fossils on Earth discovered

Earth’s oldest fossils have been found in Australia by a team from the University of Western Australia and Oxford University. The microscopic fossils show convincing evidence for cells and bacteria living in an oxygen-free world over 3.4 billion years ago.
