The Royal Institution・2 minutes read
Viruses, despite their unique structure and behavior, continue to be a subject of debate among scientists regarding their classification as living organisms. Their rapid evolution, massive genetic diversity, and crucial role in ecosystems highlight the complexity of defining life in the context of viruses.
Insights
- Viruses, despite lacking cellular components like enzymes, infect cells, replicate using host machinery, and release new viruses to infect other cells, highlighting their unique life cycle distinct from traditional life forms.
- The vast genetic diversity of viruses, estimated to be incredibly numerous on Earth, plays a crucial role in ecosystems by impacting processes like photosynthesis and oxygen production, showcasing their significant ecological importance beyond their role in causing diseases.
