Episode notes
Why Definition Matters
- Defining life matters because it affects how we treat organisms and resources.
- Crystal Rogers urges understanding life to avoid destroying it and to protect it.
List Of Life Criteria
- The classic 'list of life' includes organization, reproduction, growth, energy use, homeostasis, response, and adaptation.
- These criteria help classify organisms but leave borderline cases unresolved.
Why Viruses Are Tricky
- Viruses use host machinery but lack their own metabolism and self-reproduction.
- Crystal Rogers argues that dependence on hosts disqualifies viruses as fully alive.
