Many of the invertebrate creatures known as mollusks build interesting shells. An article titled “How Seashells Take Shape” describing a study of mollusk designs appeared in the April 2018 edition of Scientific American (page 70). The article begins with this paragraph:
“Mollusks are fabulous architects. They build houses that protect their soft bodies from predators and the elements–shells of uncommon strength, durability and beauty. Many of these shells have spectacularly complex shapes–logarithmic spirals bedecked with fractal spines or other ongoing elements, all executed with near-perfect mathematical regularity. Yet mollusks, of course, know nothing of math. How, researchers have wondered, do these humble creatures produce such intricate patterns so precisely?”
The article goes into the mathematics of the shells and how the animals use complex processes that scientists are still studying. It isn’t just the shapes that are an issue here, but also the physical properties of the shell material including elasticity, ductility, tensile strength, and the use of oscillatory systems. Scientists are trying to understand the fractal-like spine pattern in some mollusk designs. Also, the researchers are curious about why 90 percent of mollusk shells are right-handed and only 10 percent are left-handed. Other “exquisite ornamentations” create a mystery for scientists to study.
Romans 1:18-22 tells us that “we can know there is a God through the things He has made.” The complexity of something as basic as a seashell can speak to us about the design God has used in everything He does. It is only with the advent of mathematics and engineering that we can duplicate what we see in nature. Seashells are an intricate example of the design of living creatures.
