FEATURES OF THE EVOLUTIONARY DEVELOPMENT OF LIFE FORMS OF HIGHER PLANTS
Climatic cycles associated with global phases of create gasses are the reasons of oscillation ecosystems and their constituent. Ecological capacitance of systems increases or decreases due to the appearance of new ecological niches, which creating favorable conditions for expanding or narrowing opportunities of adapting new types of organization of living organisms and their significant changes. Conjugacy of the biological evolution of living organisms with geological crises and periodic variations in solar activity is observed. Direction in the development of plant life forms since the beginning of their occurrence was quite varied. The most deeply the development of life forms was developed for flowering plants, starting from of different groups of gymnosperms. The main reasons for selection of life forms are due to challenges facing researchers
