Hello. I'm in need of some information (if even just a name) on experiments performed that attempt to create amino acids through simulating earths environment back in its earlier stages. The only one I've seen any information *slightly* in-depth on this is the old Urey-Miller experiment with the Spark Chamber from 1953. Which I am not exactly happy with at all. Considering most of the circumstances and results were not fully explained, which if they were, one would understand that the experiment is pretty "iffy" in proving amino acids could be formed. Considering the facts that to achieve his results of 85% tar, 13% carboxlic acid, and 2% amino acids he had to:
1) Use no Oxygen, which didn't make much sense to me considering I thought that there was suppose to be MORE oxygen then there is today in the atmosphere along with the fact if there was Ultraviolet light and Water in the atmosphere, when the ultraviolet light hit the water it would create oxidation in the atmosphere
2) Use a "cold trap" to protect the amino acids that were formed from being quickly destroyed by the inital spark that created them.
The best I've seen on this matter has actually been experiments done by NASA that produce amino acids through conditions that mimic deep space environments oppose to earth environments. Suggesting that Earth may have been seeded with amino acids from space in its earliest days. To conduct their experiments, the research team simulated space-like conditions by freezing mixtures of molecules (such as wood alcohol and ammonia) which are abundant in interstellar clouds.
This research started through the theory called the Bonner hypothesis, that proposes that left handed radiation in space (from a rotatin neutron star for example) could lead to left handed amino acids in space, which would explain the left handed amino acids in meteorites.
I'm really excited about the NASA experiments, but I'd still like to see more involving earth conditions before I turn to space as the answer.
So with this post I'd mainly just like to hear peoples theories backed up by some experiments and information that I could look in to, because for the past couple of days I've been looking around about this and have mianly only come upon creationists poking fun at all the gaps we've left through previous experiments.
