Simple chemical composition
C
Complex cellular structures
D
Presence of carbon-based compounds
Verified step by step guidance1
Understand the context: The question is about the characteristics of the first organic molecules on Earth. These molecules are believed to be simple and fundamental to the origin of life.
Identify the characteristics listed: The options given are 'Ability to replicate', 'Simple chemical composition', 'Complex cellular structures', and 'Presence of carbon-based compounds'.
Analyze each characteristic: The first organic molecules were likely simple in structure, capable of replication, and carbon-based, as carbon is a fundamental element in organic chemistry.
Consider the complexity: Complex cellular structures are associated with more advanced forms of life, not the first organic molecules, which were likely much simpler.
Conclude which characteristic does not fit: Based on the analysis, 'Complex cellular structures' is not a characteristic of the first organic molecules, as they were simple and not organized into complex structures.
