The famous Stanley Miller experiment used a flask, an electrical discharge to simulate lightning, and molecules of everyday substances like water, ammonia, and methane. In other words molecules that are present in nature and their components are present in DNA. The theory was that the early earth was a volatile place with large amounts of the basic molecules and at one phase in the earths evolution constant storms and lightning. The experiment successfully produced some amino acids. Given the vast amount of time there was an opportunity for billions of trillions of different combinations of these molecules and that a chance "stringing together" of these amino acids capable of replication could occur.
The first self replicating proto life may have been proteins, viruses, prions, enzymes or all the above. The smallest structures in the DNAverse.

How did Stanley Miller contribute to biology?
Stanley Miller conducted experiments that showed that simple organic molecules can form from an inorganic 'soup'. These experiments show that organic molecules could have formed from the inorganic componets of the earth early in its history.
Miller and urey's experiments attempted to demonstrate?
The Miller-Urey experiment combined amino acids and other chemicals thought to be a part of the primordial soup. The experiment attempted to demonstrate the conditions on Earth in its early years.
Harold Urey and Stanley Miller were biochemists that were able to?
Harold Urey and Stanley Miller were able to prove the hypothesis that conditions during the early portion of earth's formation were conducive to complex chemical reactions. These reactions formed amino acids, which are the bases of organic compounds that lead to life on earth.
Who were Stanley Miller and Harold Urey?
Stanley Miller and Harold Urey were two scientists who send electrical currents through gases that were believed to be Earth's early atmosphere (water vapor, ammonia, hydrogen, and methane). When the gases cooled, they thickened to make a salt water-like liquid that had things in it like amino acid, what is found in present-day cells.
In their laboratory simulations of the early Earth Miller and Urey observed the abiotic synthesis of which molecules?
There are four molecules that are found in the 1st Miller Urey experiment. The four molecules that were found were hydrogen, steam, methane and ammonia.
What did Stanley Miller do?
Miller took molecules which were believed to represent the major components of the early Earth's atmosphere and put them into a closed system .

What materials did Harold Urey and Stanley miller use to create the conditions of early earth in their laboratory?
they used an electric current.

What did Stanley Miller contribute to the origin of life?
Stanley Miller conducted the famous Miller-Urey experiment in 1953, which demonstrated that amino acids, the building blocks of proteins, could be formed under conditions simulating early Earth. This experiment provided support for the hypothesis that the building blocks of life could have arisen from simple chemical reactions on a young Earth.

What has the author henry Stanley written?
henry Stanley has written: 'my early travels and adventures in africa and asia'
What was an early car fueled by wood or coal?
Stanley Steamer
How did early settlers get to Miller Place?
well, Miller Place was built in the 1800's but we do not know when the settlers settled there.
What country began to colonize Indonesia in the early seventeenth century?
The Netherlands began to colonize Indonesia in the early seventeenth century.
