Greenland Stromatolites and Faux Fossils

An old joke which showed up periodically during my college graduate work said, “Be sure your data conforms to your conclusions.” Because grants and scholarships depended on having success in your scientific research, it was tempting to cherry-pick data to support whatever you were claiming about your topic. That problem is still with us, and it has shown its head in reports of Greenland stromatolites.

Stromatolites are fossil deposits made by algae. (The picture shows a stromatolite fossil.) We see them not only in some shallow marine environments today, but we also find them in some of the oldest rocks on Earth. The Gunflint Chert along Lake Superior in Ontario contains some of the earliest stromatolites, but the rocks in Greenland are even older. Because many theories of the development of life on Earth depend upon finding marine life forms in Earth’s oldest rocks, there have been several premature news reports of Greenland stromatolites.

Abigail Allwood is recognized as an expert on stromatolites and has studied the oldest known stromatolites in Australia. She went to Greenland to examine the Greenland stromatolites. She concludes that they are not fossils, but only rocks that have experienced a great deal of tectonic activity. Ms. Allwood collected rocks just a few feet from the claimed stromatolites and found significant evidence of diastrophism, a type of plate tectonics which deforms Earth’s crust. She found no evidence of real fossils.

Naturally, the authors of the original paper on the Greenland stromatolites disagree with Allwood, but that is the way science works. Scientific testing answers the questions of authenticity and eventually reveals the truth. Unfortunately, false religious theories are frequently untestable and stay in existence for a very long time.

In science and faith, we should follow the evidence wherever it leads. It appears that in the case of the Greenland stromatolites, we have faux fossils and not the real thing.
