This image of the beautiful smile on this young woman's face demonstrates the remarkable arrangement of human teeth—our “pearly whites” as they say in the USA. This provides empirical evidence of managed order and arrangement, as this brief article will demonstrate. 

How could an unmanaged process produce this organised “symphony of function”—even if multiple lifetimes are involved? — See the article 'Pearly Whites—Superlative Design, Placement, and Function?' 

Note also the accompanying illustration of the two layers of teeth. Observe that each tooth design has an assigned function to handle the required cutting / tearing / grinding of all types of food. And note the functionality of this ideal arrangement of teeth from front to back:

• The incisors, the front teeth, cut and tear the food.
• The canine teeth next to them are extra strong (having the longest root of any tooth in the mouth) and have a sharply tapered design to assist in piercing and separating food. 
• Then the premolars, further back, with their flat but ridged surface, efficiently crush and grind down to assist in preparing a bolus of food ready for the digestive process. 
• Finally, the strong molars at the back, six upper and six lower, employ the power of the jaw to grind and chew the food into smaller, more digestible pieces. 
   

The theory of “natural selection” supposes that features are already available—functional and working effectively—so they can be “selected” as superior to other developments (or absence of such); the concept of managed design is avoided in the traditional narratives. This begs the question of where within the fossil record are the many failed alternative evolutionary arrangements of teeth, given the colossal geological timescales portrayed in the narratives? 

Is it reasonable to suppose that each tooth simply emerged through a long chain of fortunate accidents—each with its precise rigidity, its finely tuned edge (sharp, but not too sharp), and its ideal uniformity of size; that over time, this spontaneous sprouting just happened to form the familiar half-moon arc of the upper jaw, with mirrored pairs perfectly aligned on either side?

Also, was this symmetry merely a by-product of evolutionary left-right patterning, as some theorists suggest?

If we were to accept this argument for mirroring—that a feature of symmetry-of-form on both sides of the human body is playing some part—then what of the lower jaw? This has no correlation to any kind of left-right equivalence! Did these teeth also arise one by one, in a different architectural style, yet somehow they evolved to correspond seamlessly with their counterparts in the upper jaw—creating an arrangement that is not just symmetrical, but one that is functionally complementary?

Could this be the work of blind chance; undirected growths iterated over eons of time that happen to produce this functional, attractive, and uniform arrangement? How did evolution maintain the controlled consistency of form throughout this time? Supporters of orthodox evolution may prefer to believe that this is possible; however, how would evolution fashion, or sculpt, the design of our pearly whites if it had no concept of the intended purpose of each tooth?

Does not such anatomical choreography strongly hint of something deeper at work here?
