New Understanding In How Life Formed On Earth

Straight from Dvorak Uncensored: “In follow-up work to Miller and Urey’s groundbreaking study look at the synthesis of organic compounds in a primordial environment, it was shown that RNA monomeric bases could form under conditions similar to those of a prehistoric Earth. More recent work has shown how such individual bases, floating in a water environment, could link together into chains. [...] A critical question that remained unanswered, though, was how the ancient RNA enzymes could survive.

Now researchers at the MRC Laboratory of Molecular Biology in the United Kingdom think they have cracked that puzzle. By placing RNA inside liquid pockets of water encased inside cooling ice, they found that RNA enzymes could function and at the same time escape degradation.

Thus the origin of life on Earth might not have been in a deep-sea vent or open ocean, but in a cold muddy puddle in the icy north or south, which contained a mix of water and organic byproducts of freed carbon from the Earth’s crust.

Over time this life form could have built up an arsenal of useful chemicals — evolution at its most basic microscopic form. The most critical developments would have been the creation of a protective phospholipid bilayer, the creation of protein enzymes to offer faster catalysis, and last, but not least, the switch to the more chemically stable DNA. Once a self-replicating RNA-lifeform gained these adaptations, it would at last have been ready to venture into warmer climates and begin to survive and reproduce, capturing the sun’s power to fix energy in carbon-based molecules.

From there a long evolutionary road lay ahead, eventually reaching man and our zoological peers in the modern world.”
