Hero Shrew Spine Design Glorifies the Creator
When you first look at a hero shrew, you might wonder, “How in the world did this critter get this name?” But these little mole-like creatures are considered to be the Clark Kents of the animal world—their superpowers are hidden under humble exteriors. New research into the amazing structure and function of the hero shrew spine is revealing amazing engineering that utterly defies evolutionary speculation.1

Nothing else in the animal kingdom contains the extreme spinal structure and strength of hero shrews.2 Their highly unique and unusual backbones can withstand the weight of a full-grown human standing on top them. The hero shrew’s spine has interlocking vertebrae that make it extremely strong and rigid when it is compressed (Figure 1). Interestingly, the shrew’s backbone is flat on both the top and underneath. It also features plentiful amounts of broad side flanges that have lots of finger-like projections forming a nearly circular cage around the entire spine (Figure 2).

To more fully ascertain how the design of this structure gives the hero shrew its amazing spinal powers, scientists used a 3-D X-ray technology to scan the internal features of vertebrae using 20 different specimens.1 For a comparison, they also included scans from a goliath shrew that is similar in size to the hero shrew, but the goliath shrew has a standard mammalian backbone. The goal was to analyze the density and cellular structure of the interior of the bones and then combine that analysis with the morphology data of the outward mechanics of the spine.

Compared to the spine of goliath shrews, hero shrews have many more and much-wider vertebrae. Internally, the hero shrew’s cellular structure exhibited many reinforcing rod-like structures that made the otherwise spongey bone very dense and strong. These struts as they were called, were primarily oriented in a head-to-tail direction compared to the goliath shrew where the struts seemed to have a more random orientation. This strut orientation within the bone tissues further maximized the strength and power of the spine.

The bottom line is that hero shrew spines don't just look tough and formidable from the outside, but their inside cellular structure is highly designed to maximize strength as well. Optimization is a hallmark of design.

What purpose this unique overall design is serving the shrew has yet to be determined since little is known about the behavior of these creatures in the wild. One hypothesis is that this trait facilitates foraging for food by allowing the shrew to scrunch up and then push and force its way through difficult places to get at insects for lunch.

Unique adaptive designs in shrews and other creatures continue to amaze biologists. And of course, evolutionists have no clue as to how these highly complex and optimized all-or-nothing traits could have appeared suddenly with no evolutionary precursor. The obvious conclusion is that an all-powerful and omnipotent Creator engineered these creatures from the beginning.
