Abstract
Evolutionary processes are conditioned both by unique phenomena and probabilistic ones. Given probabilistic factors, one may speak of changeability of evolution. This essay attempts to model evolutionary processes by modeling changeability in the natural sciences. Yet a framework of determinism and indeterminism appears inadequate to apprehend evolutionary processes. Autodeterminism is a more promising framework for addressing the causal, functional, and probabilistic dimension of evolution. Such an approach ensures the possibility of perceiving and presenting the complexity of evolution. The essay proposes that the synthetic theory of evolution conjoins factors of evolution, determinism, and changeability. The question still remains whether one can say that real being, which exists in the stream of time, is the subject of philosophy. This puzzle may be resdved by showing that besides the scientific cognition of nature, there is another possible cognition--the philosophical cognition. This is reflected in a significant group of problems of philosophical cosmology which are not addressed by the natural sciences due to their research methods.
