Hey, Ilovelucy - here's a really cool article posted on RDF about a return to the Miller-Urey experiment. This was an experiment whereby scientists demonstrated that with some relatively simple starting molecules, thought to be in earth's early atmosphere, like nitrogen dioxide, methane, ammonium, and the likes - put through experiments to mimic the conditions of early earth and heated to mimic what might go on in the likes of a volcanic vent - you can quite easily produce nucelotide bases, some simple sugars, and some amino acids - representatives of three of the four crucial building blocks of life: nucleic acids, amino acids and carbohydrates. (The fourth group of building blocks, lipids, have also been produced from oxalic acid, in similar experiments)
This was one particular experiment that helped put to death the idea that there was some unique 'vital force' contained within living organisms that couldn't ultimately be explicable in terms of ordinary physics and chemistry. It goes some way to demonstrating not only that we are made of the same molecules and laws of physics as everything else, but that precursors of the main molecules that make us are not somehow chemically special, and are relatively simple to synthesise under conditions mimicking those of the early earth - and as such there's a credible route of the complexity of life, and modern molecular biology, emerging from simplicity - even if the story is not yet completely fleshed out, and all the intermediate steps between non-living and 'living' chemistry, not yet filled in. It was a truly remarkable experiment, and a great credit to the intelligence and insight of the men who did it.
Anyway, here's the article on it on RD.net - and be sure to read the very few comments!

You'll also notice that it's one of the very few science-related articles on the site. There's about as much science there as there is meat content in a Tesco Value sausage roll. They say they're for reason and science, but my critical thinking skills and evidence-based understanding of their site make me take that with a pinch of salt. I don't know - maybe they're just non-practising, but still feel a nominal affiliation?
