The Relative Failure of Biomimicry Points to a Designer
The Relative Failure of Biomimicry Points to a Designer
Over the years, we have highlighted the apologetic value of biomimetics, which is defined by Merriam-Webster as “the study of the formation, structure, or function of biologically produced substances and materials (such as enzymes or silk) and biological mechanisms and processes (such as protein synthesis or photosynthesis) especially for the purpose of synthesizing similar products by artificial mechanisms which mimic natural ones.”1 Our informal apologetic argument has been basically the following reasoning from the lesser to the greater: If the imitation is designed, then it stands to reason that the superior, more sophisticated object of imitation also was designed.2
A wide variety of researchers are involved in biomimicry, but the relative failure of their admittedly ingenious efforts to mimic God’s creation serves to underscore the role of divine design in the production of natural structures. To use Paul’s words, “[T]he foolishness of God is wiser than men, and the weakness of God is stronger than men” (1 Corinthians 1:25). From time to time, it is helpful to remind ourselves that researchers continue to admit the superiority of natural, biological “designs” over synthetics. Consider several examples:
Echolocation in Bats
We have previously noted the sensitive hearing bats employ as a “sonar” system that allows them to fly speedily through stalactite-filled caves and seemingly impenetrable wooded areas, and we have seen how bat echolocation has served as the inspiration for the development of sonar systems.3 The American Association for the Advancement of Science, which publishes a variety of journals under the masthead Science, is by no means friendly to creationism.4 Yet, consider this organization’s assessment of the state of biomimetics as it relates to echolocation:
Today, the remarkable abilities of bats are the inspiration for building better sonar systems. Bat echolocation is still more sophisticated and effective than any man-made sonar, and scientists around the world are working to fully understand the details that allow bats to perform aerial acrobatics at high speeds, in cluttered environments, amidst potentially interfering sounds—all using their mouths and ears.5
Despite the best efforts of human designers to mimic God’s creation, there has never been a sonar as effective as what bats already use. Surely their capability had a designer. (What’s more, the vast majority of bat species would not exist today if they lacked echolocation from their very first generation.)
Spider Silk
For years we have noted the amazing strength and flexibility of spider silk, which has served as the inspiration for new ways of making bulletproof vests, suspension cables, and artificial tendons.6 In 2017, Smithsonian Magazine reported that researchers at Cambridge University had created a new material that mimicked spider silk, was 98% water, and offered new opportunities for developing products from bike helmets to parachutes.7 Unfortunately, the synthetic substance was nowhere near as effective as natural spider silk. Darshil Shah, an engineer at Cambridge University’s Centre for Natural Material Innovation, told Smithsonian: “Spiders are interesting models because they are able to produce these superb silk fibers at room temperature using water as a solvent…This process spiders have evolved over hundreds of millions of years, but we have been unable to copy so far.”8 As of 2025, “challenges such as cost-effective production, scalability, and regulatory approval remain barriers to widespread adoption [of synthetic spider silk].”9 Yet spiders themselves have no such trouble mass-producing spider silk.
As a 2015 Wired story points out, “[S]o far, every group that’s attempted to produce enough of the stuff to bring it to the mass market, from researchers to giant corporations, has pretty much failed.”10 Despite the best efforts of human designers to mimic God’s creation, there has never been a synthetic spider silk as effective as what spiders already use for their very survival. Surely their capability had a designer.
Gecko and Mussel Glue
We have previously noted the gecko’s adhesive foot pads and the mussel’s ability to adhere to fully immersed surfaces.11 Drawing their inspiration from these two creatures, researchers about 20 years ago produced “geckel,” a glue made of nanotubes and protein polymer. Geckel has been used for water-resistant bandages, drug-delivery patches, and medical sutures to close wounds that bleed heavily. But years after the exciting announcements about the adhesive’s potential, there still is no mass production of the product. Phillip B. Messersmith of Northwestern University, who developed geckel, made a statement in 2007 that still holds: “The challenge will be to scale up the technology and still have the geckel material exhibit adhesive behavior.”12
Hibernation
Hypothermia is a medical emergency that occurs when an animal’s body loses heat faster than it can produce it, causing a dangerously low core body temperature.13 We have previously observed that certain animals, such as the American black bear and the arctic ground squirrel, exploit hypothermia by entering hibernation, a temporary, sleep-like torpor during cold, winter months.14 For decades, researchers have hoped to reduce the danger of certain tedious medical procedures, particularly when ill or injured human patients are involved, by inducing torpor. In 2023, Hong Chen, a professor of biomedical engineering at the Washington University School of Medicine, and her interdisciplinary team, induced a reversible torpor-like state in mice and rats by using focused ultrasound to stimulate the part of the brain that helps to regulate body temperature and metabolism.15 Chen wrote, “The capability of synthetic torpor to regulate whole-body metabolism promises to transform medicine by offering novel strategies for medical interventions.”16
And yet, any widespread application of artificial torpor appears to lie far in the future. One of the researchers on Chen’s team, Wenbo Wu, stated:
Our challenges include overcoming metabolic differences among animals and humans, choosing the correct dose of medication and creating ways to allow a reversible torpor-like state… Collaboration among scientists, clinicians and ethicists will be critical to develop safe, effective and scalable solutions for synthetic torpor to become a practical solution in medicine.17
Note that, according to Wu, one of the obstacles his team faces is “creating ways to allow a reversible torpor-like state.” This amounts to saying that one of the challenges of the whole project is the whole project. Again, we find that, despite the best efforts of highly capable human designers to mimic God’s creation, the torpor that preserves the lives of many animals has not been successfully imitated. Surely the superior, natural processes had a designer.
Conclusion
Perhaps there will be a time when a variety of biomimetic applications become effective and widespread. This circumstance will not nullify the point that design was required for the natural exemplars. About 2,000 years ago, the apostle Paul preached to the idolatrous people of Lystra and said that God had not left Himself without witness, but had made the heaven and the Earth and the sea and all that is in them (Acts 14:15). We are logically justified in reasoning from the products of the designer to His existence (see Romans 1:20).
