If you had anything but strawman arguments to discredit evolution you'd have brought them long ago.
I see. Because in your twisted version of reality, if you haven't looked for it, then it doesn't exist. The whole theory of evolution and natural selection rests on the concept of fitness. Yet, like most of Darwinism, the concept is vague at best, and certainly not up to REAL scientific standards.
To see the frailty of the fitness concept most clearly, just look at actual attempts to explain why a given trait renders an animal more (or less) fit in its environment. For example, many biologists have commented on the giraffe’s long neck. A prominent theory, from Darwin on, has been that, in times of drought, a longer neck enabled the giraffe to browse nearer the tops of trees, beyond the reach of other animals. So any heritable changes leading to a longer neck were favored by natural selection, rendering the animal more fit and better able to survive during drought.
It sounds eminently reasonable, as such "just so" stories usually do. Problems arise only when we try to find evidence favoring this hypothesis over others. Craig Holdrege has summarized what he and others have found, including this: First, taller, longer-necked giraffes, being also heavier than their shorter ancestors, require more food, which counters the advantage of height. Second, the many browsing and grazing antelope species did not go extinct during droughts, “so even without growing taller the giraffe ancestor could have competed on even terms for those lower leaves.” Third, male giraffes are up to a meter taller than females. If the males would be disadvantaged by an inability to reach higher branches of the trees, why are not the females and young disadvantaged? Fourth, it turns out that females often feed “at belly height or below.” And in well-studied populations of east Africa, giraffes often feed at or below shoulder level during the dry season, while the rainy season sees them feeding from the higher branches — a seasonal pattern the exact opposite of the one suggested by the above hypothesis.[18]
Another problem with the usual sort of fitness theorizing becomes evident when you consider the unity of the organism and the multifunctionality of its parts. Holdrege remarks of the elephant that it “stands sometimes on its back legs and extends its trunk to reach high limbs — but no one thinks that the elephant developed its trunk as a result of selection pressures to reach higher food.” The trunk develops within a complex, multifaceted, interwoven unity. It “belongs” to that unity, not to a single isolated function. The effort to analyze out of this unity a particular trait and assign it a separate causal fitness is always artificial. This is certainly true of the giraffe, whose long neck not only allows feeding from high branches, but also raises the head to where the animal has the protection of a large field of view (the giraffe’s vision is much more developed than its sense of smell), serves as an “arm” for the use of the head as a “club” in battles between males, and plays a vital role as a kind of pendulum enabling the animal’s graceful galloping movement across the African plain.
