Nice fairy story, but that's all it is. The only molecule I saw named was Phosphoramidate DNA.
I found a paper by Szostak et al Synthesis of N3′-P5′-linked
Phosphoramidate
DNA by Nonenzymatic Template-Directed Primer Extension - PMC where in the discussion they say
quote: I.e it is a step towards but not an example of a self replicating molecule. Neither is it spontaneous polermization as the video claimed since it required a carefully constructed template. The paper didn't discuss the experimental set up but I suspect as in other cases a carefully controlled laboratory environment and carefully selected reagents is required to get favourable results. Since I asked for your best example and that has failed I need look no further.

Artificial molecule evolves in the lab , 08 January 2009 by Ewen Callaway "Joyce’s team created its own molecule from scratch, called R3C. It performed a single function: stitching two shorter RNA molecules together to create a clone of itself." In other words they started with 3 carefully constructed RNA strings and achieved ligation of the two short strings in a carefully controlled laboratory environment. Nothing like these 3 RNA strands will appear naturally. There are a lot of problems with obtaining RNA by blind undirected chemistry, but it's amazing what can be achieved by an intelligent designer. Self-replicating? Sort of. But not one that is likely to occur naturally.

What is the difference between Porsche making a 'family' of sports cars and a nested hierarchy? Or what about a nested of heirachy of vehicles in general? Would that prove that one evolved from another? (Beware Berra's Blunder) Edited by CRR, : No reason given.

You had 2 chances to give your best example. That's it.

A chiroselective peptide replicator (paywall)
The origin of biological homochirality (requires MyJSTOR account.) A cross-chiral RNA polymerase ribozyme (paywall) The eightfold path to non-enzymatic RNA replication (open access)And Jack W Szostak sums it up pretty well. "Although several RNA polymerase ribozymes have been evolved in vitro, the creation of a true replicase remains a great experimental challenge." and "In this review, I discuss recent findings that suggest that chemically driven RNA replication may not be completely impossible."

It will be interesting to see if the results of those computer simulations can be replicated in the laboratory. Although the article liberally uses "evolution" this is in the dictionary sense of change over time and is not biological evolution.

Dredge is right Message 1147. The quote did not omit "several pages" as dwise1 claimed and did not substantially distort the meaning.
When Gould said "Transitional forms are generally lacking at the species level, but they are abundant between larger groups." I think he was desperately backpedaling after he let the cat out of the bag. Edited by CRR, : link added

My impression is that the theory of Punk Eek had a brief moment in the light but is mostly not considered seriously today as a general explanation for the absence of transitional forms in the fossil record. e.g. Punctuated equilibrium - Wikipedia Edited by CRR, : No reason given. Edited by CRR, : tidy up

Except that I read your link and while the quote is an extract from the 5 pages it is representative of what Ruse said, and as such is not quote mining. Ruse's quotes from Stephen J Gould continue to reinforce the theme that many evolutionists give religious overtones to the theory of evolution
Except that Michael Ruse objects to being quote-mined like this.quote: Ruse did qualify it toward the end by saying
quote: Ruse wrote what he wrote. The quote is fair.

There is no reason why a person who accepts evolutionary theory as the best explanation of how life on earth came to be so diverse can't also believe in miracles.
Do you believe in miracles?Which ones?

"Nothing in biology makes sense except in the light of evolution." was the title of an article by Theodosius Dobzhansky published in The American Biology Teacher, Vol. 35, No. 3
As I said in Message 5 it is a hyperbolic title to grab attention. Much in biology makes sense without evolution. Just in time: A new article in EN explains why Dobzhansky’s phrase is unequivocally false. Edited by CRR, : Just in time added
