The English naturalist Charles Darwin established that all species of life have descended
over time from common ancestry, and proposed the scientific theory that this branching
pattern of evolution resulted from a process that he called natural selection. In fact, Darwin
theory dealt with the evolutional phenomena of the biosphere, not its origins. Further more,
there exist the natural worlds other than our beloved one. Compared to the large-scale structure
of galaxies, the biosphere is "microscopic". The electromagnetic and nuclear forces which rule
the world disappear in the formation of large-scale galaxy structure. Similarly they disappear in
the formation of the solar system. My previous papers showed that large-scale galaxy structure
originates rationally from an algebraic cubic equation. This paper presents the nature's selection
of the cubic roots and its application to the galaxy NGC 3275.

As stated in P. Rochette et al., "Micrometeorites from the transantarctic mountains",
micrometeorites constitute the main part of the flux of extraterrestrial matter accreting on Earth.
They are very important to understanding the composition of the solar system. Micrometeorites
have been recovered from a variety of terrestrial surfaces (desert, beach sands etc.), showing that
their deposition can be evidenced on any surface, provided that the accumulation time is sufficient,
and discrimination from terrestrial particles is feasible.
I present here my amateur activity of micrometeorite collector in the backyard and in desert sand.
Sahara desert sand brought to me by my friend Silvia Calamity.
