Question

How did the Miller-Urey experiment impact the way scientists think about the origins of life?

Use what you know about the Miller-Urey experiments to discuss the factors needed for life to arise, and speculate on whether life could arise on another planet.

Answer 1

life on Earth started with the synthesis of organic compounds from inorganic compounds. To understand what the primitive Earth was like, Miller and Urey set up this experiment. Think of this experiment as a simulation of primitive Earth. The experiment's aim was to see if inorganic molecules can be synthesized when only inorganic molecules are inputted into the apparatus.

Earth had no atmosphere. The main gases in the primitive atmosphere were methane, ammonia, hydrogen, water vapor and carbon monoxide. By inputting energy through the means of electrical sparks (simulating lightning) and warming the water (simulating heat from the sun heating up the ocean) in the apparatus, organic compounds was found days later. This experiment supports the hypothesis that organic compounds can be synthesized from inorganic compounds.
