Methane-belching bugs inspire a new theory of the origin of life on Earth

s, they evolved to fix carbon. These ideas suggest a totally new perspective. It's truly a quantum leap--a milestone."

The paper also proposes mechanisms by which Ferry and House's mineral-bound protocell could have evolved into a free-living cell, and how the metabolism of acetate to methane could have evolved based on the pathways they discovered. The genomic and proteomic analyses of carbon monoxide conversion to methane and acetate, carried out in collaboration with Northeastern's Karger, will appear later this year. The Department of Energy and the NASA Astrobiology Institute sponsored the research.
