Which of the following is evidence that supports the autogenic hypothesis for the origin of life?
A
The ability of simple organic molecules to form spontaneously under prebiotic conditions
B
The presence of complex organic molecules in interstellar space
C
The discovery of extremophiles in harsh environments on Earth
D
The existence of RNA molecules capable of catalyzing their own replication
Verified step by step guidance1
Understand the autogenic hypothesis: This hypothesis suggests that life originated from simple organic molecules that formed spontaneously under prebiotic conditions on Earth.
Consider the evidence supporting the autogenic hypothesis: The ability of simple organic molecules to form spontaneously under prebiotic conditions is a key piece of evidence.
Evaluate the relevance of complex organic molecules in interstellar space: While interesting, this evidence supports the idea of panspermia rather than the autogenic hypothesis.
Assess the discovery of extremophiles: Extremophiles demonstrate life's adaptability but do not directly support the autogenic hypothesis.
Examine the role of RNA molecules: RNA's ability to catalyze its own replication supports the idea of self-replicating molecules, which is relevant to the autogenic hypothesis.
