The tautological statement that the fittest organisms will produce the most offspring…the fittest organism being defined by circular reasoning as being the one that produces the most offspring…stays entirely within the boundary lines of a single, track meet event like high-jumping. It describes the proficiency level attained through the microevolution of that single track meet event of high-jumping.
Macroevolution hypothetically producing diversity (in our track meet analogy) has absolutely nothing to do with the gold metal high-jumper passing the relay baton to the pole-vaulter. How the high-jumper reaches gold metal proficiency…fitness in lifestyle habits…has no correlation to reaching an equivalent level of technical proficiency in the entirely different track meet event of pole-vaulting…although they each share the similar goal of going as vertically high as they can.
Identifying fictional nodes in Darwin’s tree of life…in the physical characteristics side of the equation alone…using creative imagination, would not explain the diversity of lifestyle habits for the hundreds of billions of living organisms on earth. This would only get us half-way there. Simply identifying where and when during the track meet the high-jumper passed the relay baton to the pole-vaulter…would not explain the vast differences in gold metal “lifestyle habit” techniques between these two events.
This is a part of the illogic of the tree-of-life of Darwinian common descent. The empirical relay baton of explanatory mechanism must connect each discontinuity gap between the dots being birds, fish, mammals, insects, reptiles, amphibians, plants, trees, bacteria, and fungi…which are analogous to discontinuous track and field events like pole-vaulting, discus throwing, high-jumping, and the mile-relay. These connections between hundreds of billions of distinct (and thus classifiable by human taxonomists) life-forms must account for both physical and lifestyle characteristics.
The discontinuous lifestyle habits of the multitudes of living creatures renders the hypothetical “relay baton” connection through common descent to be implausibly forced, stretched, and logically unbridgeable.
Naturalism is the philosophy that superimposes an unnatural “relay baton” to connect all of the track meet events. Naturalism creates the evidence that supports naturalism. This is circular. Take away the common descent interpretational framework and we are back in time to the neutral facts of pre-1859…the “standard Olympics track meet” of typological and discontinuous life-forms…which did not point toward macroevolution at all, prior to Darwin’s book The Origin of Species.
