source: Terra Daily | Jul 24, 06 | submitted by Ryan

Los Angeles, CA - Ten years ago, an international team of scientists reported evidence, in a controversial cover story in the journal Nature, that life on Earth began more than 3.8 billion years ago--400 million years earlier than previously thought.

A UCLA professor who was not part of that team and two of the original authors will report in late July that the evidence is stronger than ever.

"It became clear that these rocks that hosted life line up into two beautiful, coherent layers. They are not randomly distributed, as you might expect if the alternative interpretation is right. I'm very confident about that. I went to Greenland with some skepticism, but I became more and more confident as time went on that the original interpretation was right."- Craig E. Manning, lead author of the new study and a professor of geology and geochemistry in the UCLA Department of Earth and Space Sciences
