[The origin of the eukaryotic cell. I. Historical sources and current state of the concept of symbiotic and autogenic origins of the cell].

The exogenous (symbiotic) conception of the eukaryotic origin is now widely spread. It is based on the recognition of the principle of combination (addition or enclosing) of diverse prokaryotic organisms; so the complicated unicellular eukaryotic organism (eukaryotic cell) was resulted. the principle of combination takes its historical scientific sources from the ideas of Buffon. With reference to the cell this principle was claimed for the first time. In our time the exogenous conception is characterized as a "symbiotic boom", because it is widely used in attempts to explain the origin of all the main organelles of the cell (right up to the micro-bodies). The autogenetic (endogenous) conception is based on the principle of straight phyliation, on the recognition of a successive evolutionary transformation of prokaryotic forms into eukaryotic ones. In this way all the cell organelles may have an endogenous origin. This principle springing from Lamarck has got a contemporary meaning in the doctrine of Darwin. In the next papers the author will present his own analysis and generation of the present day relevant facts to find out which of these two conceptions based on quite different scientific methodological principles may be correct.
