At Gizmodo: “it now seems possible that more than one evolutionary pathway led to the first multicellular lifeforms.” That’s dangerously close to saying that all life didn’t begin with a single cell. But weren’t we all ordered to believe that because the origin of life is so fantastically unlikely that it could only have happened once?

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.
Researchers: Earth’s transition to stable oxygen levels took 100 million years longer than believed
Of course, one outcome of a shorter period during which oxygen is stable enough for complex life is — the obvious one — that all that bewildering complexity of life had to just sort of fall into place in a shorter period of time. If that’s unlikely, it’s an argument for underlying design.
Can a computer simulation show that helium compounds exist on Earth?
That could impact our understanding of early Earth. Helium is the second most abundant element in the universe but finding it on Earth is tricky. So researchers resorted to a computer simulation and found a promising possible compound: Helium-bearing compounds have, until very recently, been considered unlikely to exist under the physical conditions on or Read More…
Researchers: Earth’s oxygen rose and fell several times before the Great Oxidation Event 2.2 bya
According to the latest research, we learn from ScienceDaily: Earth’s oxygen levels rose and fell more than once hundreds of millions of years before the planetwide success of the Great Oxidation Event about 2.4 billion years ago, new research from the University of Washington shows. The evidence comes from a new study that indicates a Read More…
