question 31

Multiple Choice

Natasha Paul and Gerald Joyce's experiment sought to provide evidence that supported the theory of RNA world.

This schematic of the results illustrates which specific requirement for evolutionary change that Paul and Joyce were studying? A


B

• A) It illustrates that in certain conditions, RNA was capable of replicating.
• B) It illustrates variation in RNA sequences.
• C) It illustrates that natural selection did not occur in RNA world.
• D) It illustrates fitness differences between the RNA sequences.
