Why was the urey miller experiment conducted

Electrodes delivered an electric current, simulating lightning, into the gas-filled chamber. After allowing the experiment to run for one week, they analyzed the contents of the liquid pool. They found that several organic amino acids had formed spontaneously from inorganic raw materials.

These molecules collected together in the pool of water to form coacervates. Their experiments, along with considerable geological, biological, and chemical evidence, lends support to the theory that the first life forms arose spontaneously through naturally occuring chemical reactions.

However, there are still many skeptics of this theory who remain unconvinced. British astrophysicist, Fred Hoyle, compares the likelihood of life appearing on Earth by chemical reactions "as equivalent to the possibility that a tornado sweeping through a junkyard might assemble a Boeing from the materials therein".

Theorized mineral formed in earth's mantle found in diamond 6 hours ago. This is done in the presence of a liquid water reservoir, representing the early oceans, as well as with an apparatus simulating evaporation and precipitation. Today, January 21, JoVE, the Journal of Visualized Experiments , published a modern approach to a famed experiment that explored one of the most intriguing research questions facing scientists today—the origin of life on earth.

The protocol, titled Conducting Miller-Urey Experiments, is comprised of a modern and simplified approach to the method used by Dr. Stanley Miller and Dr. Bada's experiment could also have implications for life on Mars, because the Red Planet may have been swaddled in nitrogen and carbon dioxide early in its life.

Bada intends to test this extrapolation by doing experiments with lower-pressure mixes of those gases. Chyba is cautious: "We don't know," he says, "whether Mars really ever had that atmosphere. Some scientists suspect that nitrogen gas existed on Mars, but was blasted away by asteroid impacts billions of years ago. Credit: Nick Higgins. Already a subscriber? Sign in.
