In this video, I've explained peripherally, the origin and evolution of life on Earth and the role of Cyanobacteria using cartoony vector animations. The initial part explains the conditions of primitive Earth that led to the origin of life. In the latter part, I've explained the ultrastructure of cyanobacteria and Gaidukov's Phenomenon.
