We already know that the environment, the climate in which the atoms of
the elements formed,
was the atmosphere from the sun's surface - the chromosphere.
The variation of that environment, climate, composed and decomposed the
atoms of the elements,
or ejected them into the space around the sun as meteoric matter, from
which the earth also formed.
Similarly, in the atmosphere on the surface of the earth, a different
environment of the chromosphere,
the atoms of the elements have combined at a higher level, constituting
another kind of "atoms",
which make the transition to biostructures - viruses.
Viruses are characterized by oscillations with a certain frequency spectrum.
These characteristics are revealed by their seasonal apparition,
by the propagation mode and by the place of the interaction with the biostructures.
Viruses are always ready to compose and decompose biostructures,
(like atoms in the chromosphere), when the environment, climate, demands
it.
Climate has always been variable: daily; annually; or millennial.
In other words, biostructures are dependent on the quality of the environment,
climate.
The longest and oldest period of climate change was many millions of years
ago.
Then the sun cast a cloud around it, a belt of meteoric matter, from which
the planet Venus formed.
The cloud eclipses the earth and reduces the energy received from the
sun for a long time.
After the formation of the planet Venus,
a geologically recorded period followed - the Proterozoic Aeon.
A similar phenomenon occurred with the formation
of the planet Mercury, followed by the Phanerozoic Aeon.
Has the planet Mars experienced such climate change three times?
