Timothy Standish: I couldn’t help but notice that the time photosynthesis is supposed to have evolved doesn’t line up with either the time when oxygen is supposed to have become an important element in the atmosphere, half a billion years later, or the time that fixed carbon begins showing up in the fossil record, which is much earlier, possibly over half a billion years.

Researchers say they have a “precise estimate” for the time of origin of photosynthesis
Botanist Margaret Helder writes to comment “The point to reflect on is what all those heterotrophs did for food prior to the appearance of the autotrophs. Any organic molecules in the environment would be quickly digested if there were only organisms around with no capacity to reduce carbon.”
Researchers: Cyanobacteria were an important part of marine ecosystems 1400 million years ago
Well then, how did a complex process like photosynthesis get the time to “evolve” by natural selection acting on random mutations (Darwinism)? Researchers (wisely, for now) state such findings without making any obvious inferences. But the number of these situations is building.
If photosynthesis could really be as old as life itself…
Well, that’s good news for the hope of finding life on other planets! But researchers hoping to rush in and save Darwinism should know that if the earliest organisms could photosynthesize, an intelligent origin of life is virtually certain.
Researchers: We switched the direction of electrons in photosynthesis
Actually, it’s not clear from the release whether we are any closer to understanding why plants always choose the other direction, left to themselves. Something more is going on, probably. Nice find though.
Researchers: Photosynthesis may be a billion years older than thought … But WAIT!
“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…
