Laboratory production of RNA-like Molecules

Researchers working with that hypothesis have achieved a significant advancement toward understanding the evolutionary mystery of how components of RNA and DNA formed from chemicals present on early Earth before life existed. In surprisingly simple reactions they have produced good candidates for their precursors that even spontaneously joined up to look like RNA.

The researchers at the NSF/NASA Center for Chemical Evolution formed proto-nucleotides using two molecules known as barbituric acid and melamine so strongly resembling two of RNA's nucleotides that it is tempting to speculate that they are indeed their ancestors.

The two ingredients would have been readily abundant for reactions on a prebiotic Earth, Hud said. "And they would have been well suited for primitive information coding," he added.

Because of the resemblances and properties, some scientists already have speculated on an ancestral role for melamine and barbituric acid.

But the CCE scientists are careful not to jump to that conclusion just yet.[...]"The question is: Can these self-assemblies make the transition into what makes up life today," Krishnamurthy said.

The researchers hope their work will help expand the scientific community's approach to chemical evolution.
Or you could believe that an invisible being, who knew nothing of biology or chemistry, used magic to make all living things of their kind out of mud and did it in 6 days.

Or you can believe that God kickstarted the natural laws of physics in place.

Another increment towards unraveling the mysteries of abiogenesis. An extremely young field as science goes, yet remarkable progress keeps being made.

Creationists often say that because a complete path from nonliving to living matter has yet to be shown, evolution is somehow disproven. Nevermind that the practical applications of evolutionary theory (vaccines, agronomy, genetics etc.) continue to somehow work and there remains no better explanation of all the evidence.

very cool.   of course theists will either make up a new god, going from the personal vengeful god to a vague one that just does physics, or shoving their old god into the gaps they try to pry open between the facts.
