Question

The most significant event in chemical evolution was the origin of ______ type of molecules.

Answer 1

The most significant event in chemical evolution was the origin of self-duplicating type of molecules.

Explanation:

The first sign of self-perpetuating life was displayed by nucleic acids, which are self-duplicating (autocatalytic) systems. These nucleoproteins could replicate themselves and perform hereditary functions, which was crucial for the beginning of life. The formation of these self-replicating molecules marked the transition from chemical to biological evolution, leading to the emergence of the first primitive organisms, such as protoviruses, and eventually cellular life forms.
