Chapter 11, Problem 7CT
A scientist who discovers a prokaryote living in a hot spring at 100°C suspects that it belongs to the archaea. Why does she think it might be archaeal? How could she prove that it is not bacterial?

Why is there a debate as to whether archaea is classified as prokaryotic or eukaryotic
In 1985, a 0.5-mm cell was discovered in surgeonfish and named Epulopiscium fishelsoni. It was presumed to be a protozoan. In 1993, researchers determined that Epulopiscium is actually a gram-positive bacterium. Why do you suppose this organism was initially identified as a protozoan? What evidence would change the classification to bacterium?
Some prokaryotes, especially archaea, are capable of living in extreme environments, such as deep-sea vents, where temperatures can reach 80°C (176°F). Few organisms can survive at this temperature. What adaptations might archaea possess that allow them to survive in such extreme heat?
