title: [Evolutionary trends in the prokaryotic community and prokaryotic community-phage systems].
abstract: The Evolutionary Constructor software has been used for computer simulation of the life and evolution of communities of unicellular haploid organisms (prokaryotic cells). Opposite trends of the community evolution (simplification and complication of the genome) have been studied. It has been demonstrated that species with reduced genomes tend to replace genetically and metabolically rich species under highly favorable environmental conditions. Under unfavorable conditions, the opposite tendency is observed. It has also been shown that introduction of phages capable of killing the cells into the system may radically change the current evolutionary trend.
