7. By discharging electric sparks into a laboratory chamber atmosphere that consisted of
water vapor, hydrogen gas, methane, and ammonia, Stanley Miller obtained data that
showed that a number of organic molecules, including many amino acids, could be
synthesized. Miller was attempting to model early Earth conditions as understood in the
1950s. The results of Miller’s experiments best support which of the following
hypotheses?
a. The molecules essential to life today did not exist at the time Earth was first
formed.
b. The molecules essential to life today could not have been carried to the
primordial Earth by a comet or meteorite.
c. The molecules essential to life today could have formed under early Earth
conditions.
d. The molecules essential to life today were initially self-replicating proteins that
were synthesized approximately four billion years ago.
