Evolution: where did cyanobacteria come from? (Introduction)

David’s comment: Note my bold. It is a highly complex mechanism using quantum mechanics. The authors had to drag in horizontal transfer to fit Darwin. What is wrong with God's pre-planning for the Cambrian explosion and all of today's animals.

dhw: I do wish you wouldn’t keep dragging Darwin into it. If the authors are right, horizontal transfer could have been the method your God used. If he exists, I have no doubt his methods would have been scientific and not magical.

I nag on Darwin because I want lurkers and others to be reminded Darwin does not have any reliable answers to how evolution works.


I’d just like to draw attention to another paragraph in this important article:

"It was only with what is known as the Great Oxidation Event, roughly 2.3 billion years ago, that the element began accumulating in the Earth's primordial atmosphere to any major extent. This rise in oxygen stimulated the evolution of oxygen-breathing life, which in turn spurred the origins of the complex multicellular organisms that dominate the world now.”

dhw: You could hardly have a clearer statement that environmental change initiated/stimulated/triggered evolutionary change.

The is no word of yours that fits the Cambrian ( as the chief example of the explosion). The appearance of oxygen only allowed the explosion to happen. Your words imply causation, and we do not know the cause.
