What is the main purpose of discussing bacterial endospores and Nanoarchaeum equitans in the given text?
To challenge the standard definition of life and its criteria
In what state is an endospore when it remains dormant for long periods of time?
Alive but metabolically inert
What is the unique characteristic of Nanoarchaeum equitans mentioned in the text?
It can survive only when in contact with a host cell
Why do viruses represent an anomaly to the standard definition of life according to the text?
Due to their subcellular nature and ability to replicate and evolve
