The ÆPT take on the evolutionary energy patterning tendency:
The most basic and general ÆPT meaning of "evolution" is what happens when from a first and most simple possible energy-matter pattern a Universe allows the formation of a new energy-matter patterns with successively increased, or at least not decreased, functural complexity.
Even if it is not in all cases possible to compare and determine the difference in functural complexity between different biological patterns (e.g. different species of animals) it is ÆPT to make a distinction between evolutionary and devolutionary changes.
A devolutionary change brings about a decreased functural complexity. For example, when a member nation of the EU exits this union a devolutionary change is taking place.
The primary (leading) evolutionary energy-patterning changes are constructive, but evolution also involves secondary (trailing) functural pattern destroying but nonetheless as if 'evolution assisting' changes (i.e. all possible ways in which existent energy-matter patterns can decay or cease to exist).
From the main ÆPT perspective (i.e. an evolutionary psychophysiology type perspective primarily concerned with us humans) it appears that the phylogeny of biological energy-matter patterns has, generally considered, involved lifetime factors (or challenges) that have been
1. procreation promoting Opportunities
2. procreation preventing Threats.
As a follow-on from this "ÆPT heuristic" it is likewise ÆPT to recognize that in the case of the phylogeny of us humans the result of selection pressure from threats of CURSES-type having combined with evolutionary/selection pressures of Opportunity type has been that — to put it conventionally and hence with an implicitly shallow meaning and derogatory undertone: Much of our beliefs and behaviors/affairs/preoccupations are neurotically motivated (co-motivated).
In contrast, if the same result is put in an ÆPT way the word "neurotically" must be replaced by "EAVASIVEly"
On the scale of an entire universe, such as our own most clearly evolvable one, evolution can be described as starting-off as an energy-matter-pattern production resulting in a least complex but most ubiquitous possible 'functural' pattern followed by the emergence of successively less ubiquitous but increasingly complex energy-matter patterns.
