Which of the following would most likely be key to gathering evidence that the RNA World hypothesis is valid?
muminat

Answer:

The answer is; Simulation of early Earth conditions and long-term study of the resulting molecules

Explanation:

It is believed that the first molecules on earth were made spontaneously through reaction spurred by energy from lightning and also the heat from the earth. It is believed that these molecules over time then formed polymers through the catalysis by metals in the oceans. These polymers were able to self-replicate and also act as enzymes since they were able to fold up. This hypothesis was coined by Carl Woese, Francis Crick and Leslie Orgel in the 1960s. To prove it, the then conditions of early earth need to be replicated, data collected, and analyzed.

Evolution may produce variety and diversity in response to mutation, genetic drift and other genetic variation. These changes may pass to offspring and may express them more in one group of population.

Evolution also explain the unity among organisms by explaining their shared characteristics. This refers to their common ancestors.
