“Dr Cardona also suggests that this might mean oxygenic photosynthesis was not the product of a billion years of evolution from anoxygenic photosynthesis, but could have been a trait that evolved much sooner, if not first.” So when did the billions of years of Darwinian evolution that “gradually evolved” photosynthesis happen?

Researcher: Origin of photosynthesis founded on “incorrect assumptions”
Cardona: I shall attempt to demonstrate that these three ideas are often grounded in incorrect assumptions built on more assumptions with no experimental or observational support.
Researchers build public “library” to help understand photosynthesis
From ScienceDaily: It isn’t easy being green. It takes thousands of genes to build the photosynthetic machinery that plants need to harness sunlight for growth. And yet, researchers don’t know exactly how these genes work. Now a team led by Princeton University researchers has constructed a public “library” to help researchers to find out what Read More…
Many plankton behave like both plants and animals, challenging biological concepts
Tales from the Tree Bundle of Seedlings, or maybe best called Web of Life: Traditionally, marine microplankton had been divided similarly to species on land. You had plant-like phytoplankton, such as algae, and animal-like zooplankton that ate the phytoplankton. What Stoecker found was that some of these organisms were somewhere in the middle: They could Read More…
