In this current, modern Age of Information…it is not just that Darwinian macroevolution is incapable of getting us to the point of high-level, complicated inventions like human beings through the naturalistic process of accumulating and coordinating unguided, random-chance accidents…which is one of the huge and unanswerable holes in the theory of macroevolution…but also that there are logical stopping points in the design of every living and non-living thing…that do not continue along further pathways of development…beyond the parameters of the well-defined function and purpose of their uniquely specified arrangement of features.
In other words…the informational programs that describe the uniqueness of every living thing…are well-defined, fully debugged, and complete…without wiggle-room for major change.
In the modern, empirical science of taxonomic classification…there is no wiggle-room for the introduction of the philosophic post-modernism of the idea of truth being relative.
The clarity of the characteristics of living things that enables taxonomic classification…is inconsistent with the wide-open genetic borders required to produce the massive diversity of the living world…wide-open generic borders producing big changes that should be in evidence today in an ongoing process.
As we look out upon the natural world…this reality of the narrow bandwidths that define the unique characteristics of living things…should not be the case…if the atheistic philosophy of naturalistic materialism…if Darwinian macroevolution…was and is true.
If the enormous and complex diversity of the living world is the product of mindless and unguided processes…of randomly coordinated accidents large and small…then the horizontal demarcation graph-lines above and below the defining essence of every living thing…should not be static, settled, and at their optimum end-points of completion as we see today…but instead would be ever-moving, dynamic, still in the midst of further development…and therefore in most cases…seen across-the-board as recognizably universal phenomenon…being not specific and definitive enough to be amenable to taxonomic classification…or not existing at all.
The question can be asked…is there anything notable in the natural living world today…large enough in numbers to be categorized as a phenomenon…that have the unmistakable appearance of being in the process of going beyond their well-defined point of functional performance…that fall outside of the narrow bandwidth of horizontal lines top and bottom that establish their unique definition?
Are there incremental variations of lions that can run up to 60, 80, or 100 mph in short bursts? Are there Great White sharks that can swim after prey at the speed of 75 knots…underwater? Do we find some variations of owls at night that can fly twice faster than the current, typical owl top-speed?
There is a reason why we cannot artificially select through human breeding…to create dogs as large in size as elephants.
There is a reason why I am not an 8-foot tall, superstar athlete…on a championship basketball team…in the NBA.
There is a reason why I do not have an IQ of 300…and figured-out before lunchtime today…the cure for cancer and the formula for world peace.
In order for mindless and unguided accidents to reach the point of the massive amount of functionally coherent diversity we see in action in the natural living world…composed of billions of unique, high-level inventions having physical characteristics and life-style habits as brilliantly conceived as human beings, cheetahs, salmon, harpy eagles, oak trees, tomato plants, rose bushes, corn fields, honeybees, and golden retriever dogs…to reach this point…the reproductive borders around genetic variation would have to be wide-open, fluid, and dynamic…to even hypothetically be able to achieve the required ongoing revolution of big changes that the radically creative, philosophical equation of naturalism needs…in order to be considered plausibly achievable.
But what we observe in the natural living world is exactly the opposite.
The genetic boundaries around the putting-out of variant traits to be chosen by natural selection…have constraining limits…have horizontal graph-lines above and below the defining characteristics of each and every living thing…without the massive variation required for progressive big changes to occur over any length of time…and this reality has no exceptions.
The objection by Darwinists that evolutionary change occurs too slowly to be observable over the span of a human lifetime…is not valid.
To propose that all of observable life today has reached…in billions of individual examples…their functionally optimum sweet-spots of development for survival and reproduction…all at the same time…so as to render Darwinian macroevolution undetectable to the modern observer…is again nonsensical.
