Question

How did the experiment of Urey and Miller show the nature and practice of science?

Answer 1

They took a hypothesis (educated guess) and developed a controlled experiment to prove their assumption.  They researched their idea and came up with the best way to experiment.  The data they came up with was reported without changing it.  The experiment was reproducible so other could try it and come up with the same results.

Answer 2

The Miller-Urey experiment (or Urey-Miller experiment) was an experiment that simulated hypothetical conditions present on the early Earth and tested for the occurrence of chemical evolution. Specifically, the experiment tested Oparin and Haldane's hypothesis that conditions on the primitive Earth favored chemical reactions that synthesized organic compounds from inorganic precursors.

Although lightning storms are thought to have been very common in the primordial atmosphere, they are not thought to have been as common as the amount of electricity used by the Miller-Urey experiment implied. These factors suggest that much lower concentrations of biochemicals would have been produced on Earth than was originally predicted (although the time scale would be 100 million years instead of a week).

Similar experiments, both with different sources of energy and with different mixtures of gases, have resulted in amino and hydroxy acids being produced; it is likely that at least some organic compounds would have been generated on the early Earth

Answer 3

It showed that hypotheses and theories were welcomed in science, however they are only accepted when backed up with substantial evidence or sicentic proof, i.e. experiments.
