Stages of evolution of microorganisms.

| The first living organisms arose about 3.5 billion years ago. They apparently ate foods of abiogenic origin and were heterotrophs. The high rate of reproduction has led: to the emergence of competition for food, and therefore, to divergence. The advantage was given to organisms capable of autotrophic nutrition – first to chemosynthesis, and then to photosynthesis. About 1 billion years ago, eukaryotes split into several branches, some of which gave rise to multicellular photosynthetic organisms (green, brown and red algae), as well as fungi.
