What is critical to understand here is that the contention by Darwinists that macroevolution has a “mountain of evidence”…thereby establishing the “fact of evolution”…proceeds not from the facts themselves but only materializes (no pun intended) after applying the philosophical framework of naturalism over the biological facts in nature. The common descent viewpoint when stretched to fit over all living things can produce a tentative, provisional mountain of evidence in support of macroevolution…but only if common descent is first assumed to be true. Common descent will explain the fossil progression from the simple to the more complex over time, the homology (similarities) in design between creatures, and the biological distribution of similar creatures split apart by continents.
But intelligent design, based upon the empirical evidence of highly specified information and integrated complexity explains this natural phenomenon better. Intelligent design is a more persuasive and plausible interpretation of the evidence than is common descent.
Without the hard empirical evidence for the methodology and mechanism of how macroevolution changes a fish into a land reptile into a bird over time…having wings, feathers, and a totally unique breathing capacity to enable sustained flight…the philosophical overlay of Darwinian naturalism does not produce “overwhelming, mutually supportive evidence.”
The Darwinian model produces nothing more than the hypothetically connected structure of common descent…supported by circumstantial arguments alone…whose artificially connected structure falls apart when the concept of the discontinuities between the varied body-plan architectures and lifestyle habits of hundreds of billions of life-forms on the planet…is introduced.
The theoretically unimaginable jump across the gap of running and leaping along the ground or in the branches of trees, then “evolving” into winged flight through small, incremental, progressive steps, without any detailed supporting explanation as to the massive anatomical changes that would have to occur, is alleged by Darwinists to have happened simply because this is what is required to have happened according to the philosophical paradigm of naturalism.
The theoretically unimaginable jump from the functioning respiratory system of the gills of fish extracting oxygen from water under the surface of oceans, lakes, and rivers, to the fully functioning system of lungs in mammals breathing air above the water, must take place in a matter of seconds or immediate death follows.
This is an enormous gap of discontinuity. Small incremental change here is unimaginable. Yet for macroevolution to be valid, this discontinuity must be plausibly explainable within the unifying theory of common descent taken from Darwin’s hypothetical “tree of life” connecting all living things. Darwinists allege that this type of jump in development and diversity from living underwater to living above water…had to have occurred in small, incremental, progressive steps because it simply had to happen this way according to the paradigm philosophy of naturalism.
This type of secularly skewed argumentation is then stretched to apply to the enumerable discontinuities large and small of the billions of different life-forms on the planet, mixing the dissimilar ingredients of diversity and likeness into the theory of common descent…based in large part upon its appeal to scientists of being a unifying theory of biology, and at the same time offering a non-theistic explanation for the origin and diversity of life.
But from the start Darwinian macroevolution could not explain the Cambrian Explosion…the sudden appearance of a diversity of complex life-forms in an instant of geological time…which should also have had an accompanying and complimentary backstory of transitional intermediate life-forms appearing in the Precambrian rock strata.
