The already peculiar beliefs that creationists must entertain about their supposed creator deity have become even stranger with the discovery that North America's masked shrew actually shrinks as part of its winter survival strategy.
Imagine you're designing a small mammal intended to survive in an environment where food becomes scarce, and temperatures fall too low for typical warm-blooded activity during winter. You've already solved this issue effectively with hibernation — a successful strategy employed by numerous animals, even large ones like bears. Yet, apparently deeming hibernation alone insufficiently complex for the masked shrew, your design involves the creature further reducing its energy needs by physically shrinking, despite the fact that its small size was already a significant part of the survival challenge.
Nevertheless, this is precisely the type of scenario a creationist must accept if they reject evolution as an explanation. Evolution, as a blind, pragmatic process working without foresight, readily generates such unlikely and counterintuitive adaptations through trial and error.
Yet prominent creationist advocates continue to assert that their supposed intelligent designer deliberately creates these seemingly nonsensical adaptations—ironically claiming these designs are beyond the capability of natural evolutionary processes.
This example of Dehnel's phenomenon is the subject of a recent research paper in The American Naturalist by researchers based at the University of North Caroline Greensboro (UNC Greensboro). It is described in a UNC Greensboro press release:
