Question

A glass dish containing a few drops of water in the presence of carbon dioxide gas, nitrogen gas, and small organic compounds is heated by a flame and UV radiation. Which early Earth scenario does this set-up most closely resemble?
a.) amino acid formation from organic molecules in ocean water splashing on hot rock, sand, or clay
b.) deep sea volcanoes giving off gases, sulfur, and iron to produce organic molecules
c.) lightning in the early atmosphere, which may have produced the first organic molecules
d.) the replication of RNA near the ocean's surface in the day and night cycling of temper

Answer 1

Probably a. Since the organic molecules are already there, b and c are wrong. d is just out there.
