"World's Oldest Fossils" Might Actually Be Simple Rocks,

Geologists Question 'Evidence Of Ancient Life' In 3.7
Billion-Year-Old Rocks, NPR, Heard on All Things Considered
[www.npr.org]

The paper is:

Abigail C. Allwood, Minik T. Rosing, David T. Flannery,
Joel A. Hurowitz and Christopher M. Heirwegh, 2018,
Reassessing evidence of life in 3,700-million-year-old
rocks of Greenland. Nature, Letter | Published: 17 October 2018
[www.nature.com]

Well-accepted stromatolites in Australia are 3.5 billion years
old. The 200 million years that the Greenland "stromatolites"
would extend the record of life does not seem that significant
in terms of theories about how easy it is for life to develope.
Whether the Greenland stromatolites are fossils or not does
not change ideas about the origin of life much.
