Chemical Evolution of Self-Replicating Molecules Observed In a Lab (nature.com)
New submitter n0w4k writes: Researchers at the University of Groningen have developed a self-replicating system able to not only pass hereditary information from one generation to another, but also mutate (non-paywalled link to the paper). It is a crucial step towards Darwinian evolution of abiotic species and artificial life. According to the authors and perhaps somewhat counterintuitively, in order to fully reach this goal, a death mechanism needs to be implemented in the system. Otherwise new species can only form but not disappear.
Self-replicating chemical systems have been widely studied before; some were even able to mutate. However, this discovery provides the first example of mutating replicators which are fully artificial.
Full disclosure: I am one of the co-authors; you can ask me if you have some specific questions or suggestions — maybe they can be implemented in the lab!

Where is your god now?
Seven puppies were harmed during the making of this post.
It's like I am in the radio payola days all over again. Anand left and now, instead of hard-hitting facts, I get pussy-footed, PR-firm checked, chit. Colour me disgustipated.
