A networking resource devoted to biological soil crusts and the researchers who study them. We will provide a means for international scientists to communicate, share their research, share important news and announcements, ask questions and find collaborators. We will also provide a space for informal writing on research, opinion, and ideas (now seeking posters!).

Ancient soils reveal clues to early life on Earth

Ancient soils reveal clues to early life on Earth

New Nature paper out yesterday suggests using geochemistry that oxygen was in the atmosphere and cyanobacteria were in existence 3 billion years ago. No hard fossil evidence of the cyanobacteria exist...the line of thinking rests on the assumption that cyanos were the first oxygenic photosynthesizers. Anyways, cool paper.
