Did you just quote an article from a rubbish site to
a trained chemist who happens to be interested in
the origin of life and your comeback is that I'm
misinterpreting the abstract you didn't read, and I
should do your work for you, for free? It's an
 interesting  idea.

No, I'm being more selective. You think you can afford to believe
anything as if there was no cost attached. Nope. Keep your mind open
but not enough that your brain falls out is not just an aphorism.

You give me a mechanism how you think order is preserved in gas
phase or plasma, or how matter transport happens in solid state,
and then we talk. Is that sufficiently specific?

New Scientist is not a peer reviewed primary publication. You might
think I'm being difficult for no reason, but I'm really aren't.
Get it straight from the horse's mouth, and don't bother with
interpreters that will only garble the message.

Yes, so what?

Yes, so what?

The authors sure didn't. You did. Hint: the article has nothing
whatsoever to do with the origin of life. We already know that
prebiotic chemistry was clement enough at least in one instance.
