Replicator ecosystem created in the lab

Via Wired

It's not life (which by definition, is composed of cells), but it certainly evokes the word.

Basically, researchers created RNA enzymes with the potential to replicate with each other. Then, they added nucleic bases to the mix and the enzymes started replicating, producing more enzymes than were initially there. From there, evolution took hold and three mutant strains ended up dominating the population which were better at replicating than the initial population.

Good ol' impossible evolution in action, and an excellent experiment providing insight into early life.

I wonder where the creationists are in times like these.
