    Zikadenendosymbiose: Ein Modell Für Die Evolution Höherer Zellen ?Werner Schwemmler - 1974 - Acta Biotheoretica 23 (3-4):132-169.
    The intracellular symbiosis of leafhoppers is the first system in which the morphological description is extended to understand the principles of symbiosis on a molecular level. Host, symbionts and environment exist in mutual dependence with respect to pH, osmotic pressure, inorganic and organic substances. Symbionts function primarily as mediators between host and environment. They became integrated in the course of evolution, enabling the host to adapt to changing nutritional and other environmental conditions. Comparison with other symbiontic systems shows that this (...)

    The Triality Principle as a Possible Cause of the Periodicity of Evolving Systems.Werner Schwemmler - 1980 - Acta Biotheoretica 29 (2):75-86.
    Evolution proceeds in phases, alternatingly convergent and divergent. During the divergent phases, many variants of an evolutionary system arise, and in the convergent phases, these are brought together in a new, higher unity, which in turn varies, and so on. Thus the mechanism of evolution is trialistic, proceeding according to the Hegelian principle (in the widest sense) of thesis, antithesis and synthesis. This mechanism is at the same time mirrored in the structure of the evolving systems, being most clearly expressed (...)

    Ecological Significance of Endosymbiosis: An Overall Concept.Werner Schwemmler - 1973 - Acta Biotheoretica 22 (3):113-119.
    Animals and plants can be classified into three distinct groups according to their pH- and pO-values and the ratios of inorganic ion concentrations and organic molecule concentrations in their intracellular or extracellular saps . The origin of these types could be sought in the evolutionary change from aquatic to terrestrial environment. The widespread existence of these types in nature enables a direct comparison between the physicochemical composition of consumer and its producer. An example of such relationship was found in the (...)

    The Endoeytobiotic Cell Theory and the Periodic System of Cells.W. Schwemmler - 1982 - Acta Biotheoretica 31 (1):45-68.
    According to scientific procedure, each discipline first describes the phenomena of its research area, then analyzes them, and tinally categorizes them in a system. To date, biology has lacked such a system for its smallest building blocks, the cells. Although the theory of evolution explains certain central evolutionary mechanisms of the cell, there existed no generally accepted theory of the organization of the cell. The endoeytobiotic cell theory is suggested as a possible basis for a satisfying explanation of the structure, (...)
