    • Abstract:
      The article presents information on the ancestors of cyanobacteria, a huge phylum of filamentous bacteria found all over the world, which underwent the photosynthesis process for the first time. The genomes of 15 species of cyanobacteria were studied by researcher Armen Mulkidjanian of Germany. Four other phyla of bacteria that photosynthesise, do so with a variety of different genes. Only cyanobacteria possess all 100 of these genes. The oldest photosynthetic organisms were filamentous.
