For many years the textbooks in paleontology classes have said the stromatolite was the first life form to appear on Earth and that its formation was the product of chance biochemical reactions. Now there are some challenges to this model.
There were several reasons for promoting the stromatolite as the oldest life-form. One reason was that it fit evolutionary models and made sense as far as the production of atmospheric oxygen is concerned. The other reason was that a primitive plant which is a form of algae leaves a conical formation of calcium carbonate in the ocean today. Those formations are similar to the stromatolite formations found in ancient rocks. Scientists found those formations in such diverse locations as the Gunflint Chert in Canada, the Isua Belt in Greenland, and the Ediacaran formation in Australia. I have seen the formations in Australia and Canada, and they are very similar and easy to recognize.
It turns out that the formations appear to be volcanic and not biologic in origin. If the conical formations organically originated they should all have the point of the cone pointing up. In at least one recent find, the top of the cone was pointing down. Dissection of the cones shows they are an elongated ridge and not really a symmetrical cone. Biological cones are almost always very symmetrical. Rocks around the structures have been metamorphosed by heat and pressure. The recent conclusion of scientists studying stromatolites is that they are the product of metamorphic activity on volcanic material and are not biologic.
Not all of the experts in paleontology are willing to buy into the idea that a stromatolite results from tectonics and not biology. One of the reasons is that this would require an overhaul of the theoretical model for the development of life on planet Earth. The Bible simply says that the first life-forms God created were plants. The biblical sequence of plant formation in Genesis 1:12-13 was:
“deshe” meaning grass
Translated “grass” in KJV and “vegetation” in some newer translations.
“eseb” meaning naked seed or gymnosperm
Translated “herb” in the KJV and “plants bearing seed” in some newer translations.
“ets” meaning flowering tree or angiosperm
Translated “fruit tree” in KJV and “trees bearing fruit” in newer translations.
It will be interesting to see where the newest scientific controversy leads. But the lesson of history is that when science makes new discoveries and verifies them, they always support the biblical record if we take it literally. This appears to be one more example of that.
