Abstract

There were only a few attempts at reduction of the Darwinian principle of natural selection to physicochemical terms. The best substantiated are views of M. Eigen. He has defined natural selection in terms of kinetics of biochemical reactions responsible for selfreproduction of information carriers in biosystems. A view is advanced here that equations propose by Eigen are inadequate to describe the action of Darwinian natural selection. They offer only an informational and biophysical paraphrase of the so-called Non-Darwinian selection neglecting survival and adaptation as indispensable effects of Darwinian natural selection.
