Ironically, philosophers of science owe the Creationists a debt. For the “scientific” Creationists have constructed a glorious fake, which we can use… - Philip Kitcher

So we encounter the strategy exemplified by Morris: Talk generally about design, pattern, purpose, and beauty in nature. There are many examples of adaptations that can be used—the wings of bats or “the amazing circulatory system,” for example. But what happens if we press some more difficult cases? Well, if there seems to be no design or purpose to a feature (and if its presence cannot be understood as a modification of ancestral characters), one can always point out that some parts of the Creator’s plan may be too vast for human understanding. We do not see what the design is, but there is design, nonetheless.
Since no plan of design has been specified, Creationists have available another all-purpose escape clause. But it is precisely this feature of Creation “science” that impugns its scientific credentials. To mumble that “the ways of the creator are many and mysterious” may excuse one from identifying design in unlikely places. It is not to do science.

In almost any natural population of organisms, more offspring will be produced than are able to survive. The offspring will vary—in particular, they will vary with respect to characteristics that affect their abilities to survive and reproduce. Some organisms will survive longer and reproduce more frequently. If the advantageous characteristics are inheritable, then they will be transferred to descendants. As a result, they will become more prevalent in later generations. Over a large number of generations the common features of the population may be radically changed.

Knowledge of science can have a great impact on social and political policy. Students need to be told, clearly and directly, what statements are supported by the available evidence. It is not the teachers function to offer instead a contrived and unresolved “debate” in which one of the parties is an ill-defined position that lacks any evidence in its favor. To represent as equal ideas of unequal merit is to mislead and confuse. Because the consequences of so deceiving the students may be their later inability to perform their duties as conscientious and informed citizens, such educational practices ought to be recognized for the irresponsible charades they are.
