From the fact that there are 400,000 species of beetles on this planet, but only 8,000 species of mammals, the Creator, if he exists, has a special preference for beetles.

—John B. S. Haldane, to the British Interplanetary Society in 1951 and reported in volume 10 of the Journal of the British Interplanetary Society

That “preference” manifests in a new research finding showing that in some species of beetles the Creator has crafted designs so amazing that scientists are copying them to build a superior generation of robots.1

Last year I explained why a Creator intent on creating the greatest possible diversity of physical life on Earth, as implied in Psalm 104, would create so many more species of beetles than mammals. I also explained why most beetle species have body lengths of about 1 centimeter and why only a few have body lengths of several inches.

The largest beetles are the rhinoceros beetles. Biologists have cataloged about 1,500 different species of rhinoceros beetles. The largest attain an adult body length of six inches.

Rhinoceros beetles are amazing creatures. They are armorplated and can withstand impacts that would crush and maim other insects. They are also incredibly strong. Some species can lift more than 800 times their body weight, equivalent to a human lifting 80+ tons!

Male rhinoceros beetles have a long horn protruding from the head that they use for digging and for combat with other males during mating season. Sturdy, clean, easy to feed, and completely safe to handle, rhinoceros beetles have become popular pets in some parts of Asia. Their high protein content, much higher than beef or chicken, also makes them a potential food source.

Rhinoceros Beetles’ Unique Flight Capabilities

The wings of a rhinoceros beetle possess a design capability present in no commercial or military aircraft. They can withstand a midair collision without damage to the wing and with only a minor disturbance to the flight pattern.

The scientists who published the new research finding, Hoang Phan and Hoon Park, cut off the hindwing of a rhinoceros beetle at the wing base and attached it to a flapping machine. With a high-speed movie recording of the flapping wing in the presence of colliding objects, Phan and Park discovered that rhinoceros beetle wings are equipped with sophisticated hinges that allow each wing to independently and very quickly fold up origami style when the insect collides with an object, thereby protecting the wing from damage. Just as quickly, the hinge mechanisms and stored elastic energy can unfold the wing back into full flight mode.

Phan and Park show that the origami-like folding capability of the wings serves a shock-absorbing function during in-flight collisions. Rhinoceros beetle wings can fold and spring back into place within a single stroke. Hence, the beetles can successfully fly in highly cluttered environments.

Copying the Design Features of Rhinoceros Beetle Wings
Many commercial and military flight situations occur in environments so cluttered that flying through them in conventional aircraft would be dangerous. Consequently, the researchers followed up their experiments on rhinoceros beetles with a proof-of-concept design and manufacture of a collision-tolerant flying robot.

Phan and Park meticulously copied the designs they observed in rhinoceros beetle wings to build a miniature flapping-wing robot that is able to safely fly after encountering collisions. Figure 3 shows the flying robot they built and tested.

The flying robot weighs just 18 grams but can be scaled up to larger sizes. Potential applications include reconnaissance photography in confined spaces and hazardous environments, bomb detection and removal, and delivery of medical equipment, supplies, food, and water to trapped victims and first responders. More ambitious goals include using the beetle wing designs to manufacture collision-resistant helicopter propellers and collision-resistant passenger and military aircraft.

As with other bioinspired designs, the flying robot built by Phan and Park is wonderfully functional but not to the degree of the organism they copied. The sophisticated designs built into the wings of rhinoceros beetles testify to the existence of an intelligent, supernatural Creator, one who is far more knowledgeable, intelligent, powerful, and caring than we human beings.

About The Author

Dr. Hugh Ross

Reasons to Believe emerged from my passion to research, develop, and proclaim the most powerful new reasons to believe in Christ as Creator, Lord, and Savior and to use those new reasons to reach people for Christ. I also am eager to equip Christians to engage, rather than withdraw from or attack, educated non-Christians. One of the approaches I’ve developed, with the help of my RTB colleagues, is a biblical creation model that is testable, falsifiable, and predictive. I enjoy constructively integrating all 66 books of the Bible with all the science disciplines as a way to discover and apply deeper truths. 1 Peter 3:15–16 sets my ministry goal, "Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience." Hugh Ross launched his career at age seven when he went to the library to find out why stars are hot. Physics and astronomy captured his curiosity and never let go. At age seventeen he became the youngest person ever to serve as director of observations for Vancouver's Royal Astronomical Society. With the help of a provincial scholarship and a National Research Council (NRC) of Canada fellowship, he completed his undergraduate degree in physics (University of British Columbia) and graduate degrees in astronomy (University of Toronto). The NRC also sent him to the United States for postdoctoral studies. At Caltech he researched quasi-stellar objects, or "quasars," some of the most distant and ancient objects in the universe. Not all of Hugh's discoveries involved astrophysics. Prompted by curiosity, he studied the world’s religions and "holy books" and found only one book that proved scientifically and historically accurate: the Bible. Hugh started at religious "ground zero" and through scientific and historical reality-testing became convinced that the Bible is truly the Word of God! When he went on to describe for others his journey to faith in Jesus Christ, he was surprised to discover how many people believed or disbelieved without checking the evidence. Hugh's unshakable confidence that God's revelations in Scripture and nature do not, will not, and cannot contradict became his unique message. Wholeheartedly encouraged by family and friends, communicating that message as broadly and clearly as possible became his mission. Thus, in 1986, he founded science-faith think tank Reasons to Believe (RTB). He and his colleagues at RTB keep tabs on the frontiers of research to share with scientists and nonscientists alike the thrilling news of what's being discovered and how it connects with biblical theology. In this realm, he has written many books, including: The Fingerprint of God, The Creator and the Cosmos, Beyond the Cosmos, A Matter of Days, Creation as Science, Why the Universe Is the Way It Is, and More Than a Theory. Between writing books and articles, recording podcasts, and taking interviews, Hugh travels the world challenging students and faculty, churches and professional groups, to consider what they believe and why. He presents a persuasive case for Christianity without applying pressure. Because he treats people's questions and comments with respect, he is in great demand as a speaker and as a talk-radio and television guest. Having grown up amid the splendor of Canada's mountains, wildlife, and waterways, Hugh loves the outdoors. Hiking, trail running, and photography are among his favorite recreational pursuits - in addition to stargazing. Hugh lives in Southern California with his wife, Kathy, and two sons.
