@Ralph 2,
Since life has been estqablished for about 3.8 Billion years, the Pasteurian "Law of Biogenesis" has difficulty in not being demonstrated in the present world, since itd be nigh on impossible to provide an abiotic surface somewhere without the use of a "claen room". Actually, to science , PAsteurs "Law" is not a law at all, just a demonstration of how infested this planet is with life.Its almost an oxymoron.
As far as experiments are concerned, we have to consider SChrodingers question about the definition of life itself. SInce its fairly easy to understand that life is a process of organic chemistry (even the Creationists and IDers try to use the findings of organic chemistry to show us their "irreduceably complex forms". SO, the search for proto life (WHICH HAS NOTHING TO DO WITH EVOLUTION ) has involved three basic focii.
1.Life was introduced onto our planet ("panspermia") of Hoyle and others
2The basic chemicals of life were introduced onto the planet by repeated meteorite strikes in the early earth atmosphere
3Life developed here on earth by several possible chemical/geological interactions.
Most modern chemistry considers numbers 2 and 3. The latest, novel, experiments are Venters "Top down" search for the origins of life, where he and colleagues have sequentially removed components from prokaryotic cells (those with no nucleii) and are trying to establish a base level where, below which, a cell is no longer living, that is , the major responses to the environment and self regulation are no longer noted (These include replication, metabolism, tropic responses etc). This has been going on for less than a year or so , Im not sure where theyre at as of Oct 17, 2010.
But , in a capsule, there are quite a few actual investigations ("experiments") on the search for how life began.
A. Work in the 1970's had successfully produced protenoids having several characteristics of life (FOX), and these protenoid searches have stimulated more modern woprk into the roles of lipids, phospholipids, proto nucleics etc.
B, SOme have looked at syntheizing specific life related (left handed) amino acids and nucleotides (Rodgers)
C. Theres been success in extracting metalize porphyrins out of a formaldehyde proto atoshere under specific geochemical conditions (Baker)
D.STudies about complex organics seen in districts of outer space(Belloche)
E.PAH's and nucleotides have been studied and identified from meteorites (Jura)
F.Spectral analyses showing several nucleotides(at least half of the 20 needed for life) all from cometary bodies (NASA)
G The ratios of L v D amino acids and uracil and xanthine in meteorites (Breslov,Cooper, Cronin)
H. Prebiotic reactions oin sepecific geochemical environments (Martins)
I.Autocatalysis of adenosine esters into one of the key energy compounds in the cell (SCRIPPS)
J Substitution of other organic chemicals that act as pre RNA compounds in replication and metabolism (Schuster)
K. There are at least 10 different mechanisms proposed for the first production of a living cell, and all are based upon different key catalysis means (Sulfur/ iron reducing environments, The "Clay /surface reaction hypotheses) etc
ALl these have key workers and research work being done
WHile no one has yet been successful in the creation of a living cell, each has been key in providing some key chemicals and organic molecules that perform the basic activities that a living cell performs. It all gets back to answering what SChrodinger thought was a game stopper, when all he did was awaken scientific minds to this event and fill them with a mission.
SO, were either directly made of "Star stuff" or we have been molded and formed by routine geochemistry here on the planet. I dont have any answers (Anyway, its not my area) but I can wait,since we find out new things each day, so whose to say that some things will NEVER be found out?
Quote: If Physical Science cannot demonstrate something to be a FACT through the scientific method, then it is not a FACT,
. You seem to be stuck in the early Rennaissance. Science doesnt have all the answers whenever you need them. BUT, it does have much better ideas as to how to get them than does some worldview that defaults to the concept that "Then a miracle occurs". I find that outlook terribly boring .
