Classification of Living Organisms

The video discusses the evolution of the classification of living organisms, highlighting significant changes in the 70s and 80s. It introduces the three-domain system proposed by Carbus in 1977, which divides life into Bacteria, Archaea, and Eukarya. The video explains the differences between prokaryotic domains and details the characteristics of eukaryotic kingdoms: Protista, Fungi, Plantae, and Animalia. It concludes with a summary and a call to action for viewers to subscribe.
