C. If microbes can live in toxic arsenic, they have evolved.
Explanation:
After reading the chapter "Earthbound Extraterrestrial? Or Just Another Microbe in the Mud?" We can conclude that if microbes can live in toxic arsenic, they have evolved. This is because toxic arsenic is not a favorable environment for any living thing. Living conditions in a toxic arsenic environment are very inhospitable for the development of microorganisms that are able to survive under these environmental conditions. However, some microorganisms can survive and reproduce more microorganisms with the same survivability. This process indicates that these microorganisms have evolved since this new generation has a feature that the past generation did not have.
