Question

Life likely evolved underــــــــــــــــــــــ .
A)a reducing atmosphere
B)cold conditions
C)oxidizing conditions
D)dehydrating conditions

Accepted Answer

It is believed that life on Earth evolved under a reducing atmosphere, which had a low concentration of oxygen and high concentration of methane, ammonia, and hydrogen. This is because it is easier for organic molecules to form and remain stable in such an environment, providing the necessary building blocks for life to emerge.
