This chapter starts with the general principles of the theory of evolution by natural selection advanced by Darwin and the Mendelian theory of heredity. Next comes consideration of the “new-Darwinian synthesis” or “synthetic theory,” which integrates both precedents into what has become the current paradigm of the life sciences. Molecular evolution and population genetics follow, including epigenetic processes. Next, special models of selection are considered, such as sexual selection and the models that account for altruistic behavior. After the mechanisms of speciation, the main concepts of systematics are explored, which facilitate understanding of different traits. The chapter finally explores the fundamental concepts of taxonomy and the methods from phenetics to cladistics, that makes it possible to evaluate the diversity of organisms and the methods for dating the fossil record.

Aim. As the genetic code is actually a protein’s code so still leaves in the shade the answer to the question that is our aim. Why in the certain time, in the right place happens the proper phenomenon during the formation of various configurations of cells, organs and organisms. Methods. Studying and analyzing the various scientific literature, we sought to theoretically give an answer to this question. Results. Synthetic theory of evolution is considering genome as a passive structure that encodes and transmits accidentally arising variations of genotypes. However, in recent years become more known the facts that indicate the genome is an active system that self-regulated and self-organized. The genome includes not only the material for evolution, but the mechanisms of its application for the creation of new genotypes and phenotypes in the future for active participation in the process of their own evolution. The modern scientific data confirm that most evolutionarily success is the genome that is capable of change. This means that in the genome there are mechanisms that control and create diverse and concerted restructuring of DNA. Conclusions. Evolution is the continuous development in which organisms survive. The evolution is typical for all levels of nature. The main active factors of evolution are a mutation, a recombination, a hybridization and a transgenesis. Keywords: evolution, genes, factors, history.

Th. Dobzhansky played a special role in the reception and development of the “synthetic theory of evolution,” as well as in the establishment of scientific connections between Soviet and U.S. evolutionists, and first and foremost, geneticists. These connections greatly influenced the development of Soviet genetics, of evolutionary theory and evolutionary biology as a whole, and in particular the restoration of Soviet genetics in the late 1960s. A discussion of Dobzhansky’s correspondence and collaboration with colleagues in his native country, moreover, allows for an improved understanding of the complex and dramatic history of Soviet genetics and evolutionary theory. It also provides novel insights into the interactions between scientists and authorities in the Soviet Union (USSR).

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.
