glacial phenomena become intensified, as well as marine transgressions and other
geological processes covering the major part of the biosphere, simultaneously and
throughout it. The acceleration and the greatest changes of the evolutionary process
coincide with these intervals. During these periods, the greatest and the most important
changes in the structure of the living matter take place, providing an evident manifestation
of the profoundness of the geological significance of this plastic reflection of living matter
against the planetary changes.
There is no theory, no exact scientific explanation for this main phenomenon in
the history of our planet. The idea has been created empirically and subconsciously, it got
into science imperceptive. Its history has never been written. This phenomenon has been
much studied by the American geologists, particularly by J. D. Dana. The scientific
thought of our century has been very stimulated by this phenomenon.
But it must and can be approached quantitatively. One can measure its geological
duration and thus numerically characterize the change in the rate of the geological
processes. This is one of the immediate tasks of radiogeology.
11. Before this task is solved, we must note and take into account that the process
of the evolution of the biosphere and its transformation into the noosphere, clearly reveals
the acceleration of the rate of the geological processes. The earlier history of the biosphere
did not know such changes as those having taken place in the biosphere during the past
few thousand years in the connection with the growth of scientific thought and social
activities of the humanity.
At least, such are the concepts that we can now infer from the study of the
evolution of the organisms in the course of the geological time. For the geological time,
one decamiriade is far less than a second for the historical time. Therefore a thousand
years at the historical time scale is less than 300 million years at the geological time scale.
This does not contradict those great biosphere changes that took place, for example, in the
Cambrian, when the calcareous skeleton elements of the macroscopic marine organisms
emerged; or in the Paleocene, when the mammalian fauna was formed. We should not
forget that the time when we live corresponds geologically to the critical periods of the
above type, for the glacial period is not finished yet: the rate of
