Giant Viruses Blur The Line Between Alive and Not

The video explores the discovery and characteristics of giant viruses, known as gyrusses, which challenge traditional definitions of viruses and cellular life. These viruses, like Mimivirus, have large genomes and possess genes typically not found in viruses, raising questions about their origins. Two main hypotheses are discussed: one suggests gyrusses evolved from complex cells, while the other proposes they acquired genes from host cells through horizontal gene transfer. The video highlights the ongoing debate and the implications of gyrusses on our understanding of life and evolution.
