In the previous section, we have seen how through Spin the primeval formations of Nature --the xenobase-combs and xenoverses can be formed. The Spin is the product of collissions and with each collision the Spin can only increase as the axis of spin (AOS) is not fixed and can rotate freely without constrain.
A rotation of 180º of AOS amounts to a reversal of the direction of the Spin.

 The role of the Spin is remarkable indeed because the Spin and nothing else was able to create a qualitatively new (and more complex) object and, as such, the Spin must be the primary motor of evolution in Nature. We encapsulate this recognition into

	The Fifth Fundamental Principle of Nature:   In Nature, the primary motor of evolution is the Spin.
	This recognition of the crucial role of the spin in Nature is monumental. As we look around, up into the cosmos or down into the atom and below, we see that everything spins! Wow!
	It is as somehow all objects of Nature would tell us: We are here because of the Spin! We are, in the way that we are, because of the Spin!

As just noted above, the primeval spin at the base Level of Organization of Nature (LON) can never decrease in magnitude. The spin, on the other hand, by The First Fundamental Principle of Nature, cannot increase its magnitude forever. Indeed it will exist a moment, called the breakup moment, when the increasing Spin can no longer be sustained as the spinning object will disintegrate.

Primeval evolution by being fueled by the primeval spin cannot ascend indefinitely in Nature as it will bring down, at the breakup moment, any formation created under its making. We mark this important recognition as

.

The Sixth Fundamental Principle of Nature:   A perpetual cycle of creation and self-destruction is present in Nature for any formation created.

The Sixth Fundamental Principle is manifesting its existence in all Natural Sciences.

• In Biology, called in TRUTON --the Rational Biology, this perpetual cycle of creation and self-destruction fueled by evolution is most visible.
• In Astronomy, called in TRUTON --the Rational Astronomy, the perpetual cycle of star creation and self-destruction fueled by evolution is another visible event.
•  In Chemistry, called in TRUTON --the Rational Chemistry, chemical elements of Nature, by originating during the process of stellar evolution, are an integral part of the perpetual cycle of creation and self-destruction present in Nature and fueled by evolution.
