Solution
The correct option is C Miller
- In 1953, Stanley Miller and Harold Urey did an experiment to test that organic molecules could be spontaneously produced under reducing conditions thought to resemble those of early earth.
- After letting the experiment run for a week, Miller and Urey found that various types of amino acids, sugars, lipids and other organic molecules had formed.
- Large, complex molecules like DNA and protein were missing, but the Miller-Urey experiment showed that at least some of the building blocks for these molecules could form spontaneously from simple compounds.
- From the experiments, it seems reasonable to imagine that at least some of life's building blocks could have formed abiotically on early Earth.
So the correct option is 'Miller'.
