Evolution: where did cyanobacteria come from? (Introduction)

DAVID: No one knows. The oxygen producing type appear suddenly in the evolutionary record:

QUOTE: "'It took a substantial unfolding of evolutionary time before oxygenic photosynthesis developed, perhaps because, as we know, it was a very challenging biochemistry to develop," Fischer said. (David’s bold)

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.

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. But your bold provides powerful support for design, and this is the sort of complexity that makes it impossible for me to embrace atheism. (I have already explained many times why I also find it impossible to embrace theism.)

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.”

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