The Design of Penguins

Penguins have features unlike any other living thing. The design of penguins allows them to dive over 100 feet to secure their food. National Geographic magazine lists these unique features of penguins:

1) Their wing shape is unique, allowing them to create a strong thrust underwater.

2) The wings have inflexible joints optimized for swimming.

3) The strong chest muscles allow them to lift their wings underwater.

4) They have elongated hip bones for swimming.

5) Their necks are S-shaped and can be retracted for swimming.

6) Salt-filtering glands above their eyes allow them to excrete salt they take in from the ocean.

7) Penguin bones are very dense for swimming and to withstand the stress of moving through water.

8) Their feathers are designed to adjust to temperatures and density. In hot weather, the feathers are raised to release heat. In cold weather, they lie flat to provide insulation. Penguins have patches without feathers in hot weather to decrease their weight and provide good buoyancy. They add feathers in cold weather to increase their body weight by 30%, making it easier to dive deep.

Realize that all these features are essential for living in their cold climate. To suggest that the penguins evolved from ordinary birds would require all these changes to happen simultaneously. In evolution, Dollo’s Law of Irreversibility states that once a feature is lost it cannot be retrieved. For a bird to become a penguin, Dollo’s Law would have to be broken multiple times.

The design of penguins demands an intelligent Designer to create these eight features in addition to several others. By studying the design of penguins, we can truly “know there is a God through the things that He has made” (Romans 1:20).

Why Did God Create Snakes?

An interesting question we receive is, “Why did God create snakes?” Bible students refer to the serpent in the Garden of Eden, but that was a one-time event and actually dealt with Satan, not with an animal. Why should we, living thousands of years after Adam and Eve, have to deal with venomous snakes? Why do many people have a fear of snakes and even find them repulsive?

The fact is that snakes offer some real benefits to humans, and their creation was not some kind of vindictive act by God. Scientists derived the first ACE inhibitor, a drug to lower blood pressure, from a South American pit viper. By studying sidewinder snakes, engineers have built robots that can wriggle into tight spaces to search for survivors after a disaster. Some people use snakes for food. Rattlesnake meat is a staple in Texas, and every year in March, Sweetwater, Texas, holds the “World’s Largest Rattlesnake Roundup.”

Like all animals, snakes are part of the balance of the populations of various creatures. Rodents are a major food source for snakes, and snakes also eat many insects and animals that threaten humans. Moving snakes into an area where they are not native has caused problems. That is the case with Burmese pythons that were brought into Florida as part of the pet trade and then released into the wild, where they reproduce without predators to control them. In their native environment, they eat large rodents and reptiles.

When people ask, “Why did God create snakes?” they should be reminded that they are not evil or a threat to humans in their natural environment. They have a purpose for existing and are not a negative commentary on God’s creation.

The Mantis Shrimp’s Design

Naturalistic evolution cannot explain many things in nature. For example, why do various birds display colors that offer no purpose and may make them vulnerable to predators? We see one of the most interesting examples that doesn’t fit blind mechanistic chance in the mantis shrimp’s design feature that can exert a blow 1000 times its body weight.

The mantis shrimp uses a club-like feature to strike its prey with a force so extreme that it creates imploding bubbles that increase the force. The question is how the design of the mantis shrimp’s club-like feature doesn’t harm the shrimp. Dr Horacio Espinosa at Northwestern University in Evanston, Illinois, has published a study explaining the mantis shrimp’s design.

Mantis shrimps have layers of mineral-hardened chitin arranged in bundles, with each layer rotated slightly with respect to the layers above and below. You might compare it to a stack of papers that have been twisted, creating a helix-like corkscrewing shape. This arrangement dissipates the strike’s energy and prevents shear waves from damaging the soft tissue of the shrimp.

Engineers are trying to copy this design to increase the toughness of airplane wings and wind turbine blades. They are sure to find more uses in future high-performance materials. We have previously highlighted the mantis shrimp’s design features, including its club, eyes, and visual system. The shrimp’s protective layer is one more example of a design scientists discovered in the natural world that can aid the design of objects beneficial to humans. God thought of these features first, and they are the product of intelligence – not mechanistic, opportunistic chance.

Unique Design of the Peregrine Falcon

Peregrine falcons have a unique design. This bird can dive at speeds up to 240 miles per hour to catch prey. The speed is totally vertical, which means there is a rapid, violent change in air pressure. Those who enjoy hot air balloons must be careful to compensate for the change in air pressure. Even though their assent is slow, the pressure change from ground level to even 1000 feet is significant. The peregrine falcon goes through a much greater air pressure change at a faster rate. Why don’t their lungs explode? The answer is the unique design of the peregrine falcon.

Peregrine Falcons have a bony structure in their nostrils called a tubercle. It acts as a baffle, deflecting strong shockwaves of air and allowing controlled breathing during their high-speed dives. Studies have shown that this design is unique to the peregrine falcon.

It is important to understand why raptors such as peregrine falcons exist. Some birds, such as pigeons, can reproduce in large numbers, exceeding their food supply. The creation always has a balance between the food supply and the population. When I was a teenager, laws protected the deer in Indiana’s Brown County State Park to the extent that they did not have an adequate food supply. The normal predators of deer had been killed off by humans, allowing the population to grow so large that the deer were destroying the vegetation but were still undernourished. When the authorities finally allowed hunting, the harvested deer were vastly underweight. A full-grown deer could weigh less than 60 pounds.

God designed peregrine falcons to control bird populations to avoid the same suffering caused by overpopulation. There is no evolutionary model that adequately explains the unique design of the peregrine falcon and its bony tubercle. Science strongly supports design in the natural world. “We can know there is a God through the things He has made” (Romans 1:20).

Snakebite Antivenom and AI

For most of us living in the United States, it is hard to believe that around 100,000 people worldwide die from snakebites every year. Venomous snakes have a blizzard of toxins in their bite, but the most dangerous are the “three-finger toxins,” proteins that can stop a person’s heart and ability to breathe. Snakebite antivenom is produced today by milking snakes to extract their venom.

Technicians inject a small dose of venom into a horse or other large animal and harvest antibodies later to make snakebite antivenom. When medical personnel inject the antibodies into a snakebite victim, they bind to venom toxins, shutting them down. This process is expensive and time-consuming, so researchers want to find a better answer. The 2024 Nobel Prize in chemistry went to three chemists who used artificial intelligence (AI) to design proteins that can dampen and neutralize snake venom.

People have asked us, “Why would God create snakes with venom?” It is essential to understand that snakes control the populations of rats, mice, and other disease-carrying animals. What would happen if there was no predator to eat rodents when they go underground? Rodents above ground are preyed on by foxes, bears, hawks, and eagles and killed by humans. When they retreat underground, they are safe from all of those, but snakes can go after and kill rodents even there.

When a venomous snake bites a human, it is usually because the human has invaded the snake’s territory and deliberately confronted it. I was hiking into geologically interesting areas in a National Science Foundation workshop in Montana many years ago. As we walked down an old wagon trail, I was in the back with 20 people in front of me. Looking ahead, I saw a diamondback rattlesnake coiled and sitting in the middle of the wagon tracks. It had made no effort to strike any of the people within inches of it, relying totally on its camouflage.

Snakebite antivenom is essential to protect human lives, but non-venomous animals can also cause human deaths. The late Steve Irwin showed many beautiful snakes in his TV show. When he died at age 44 on September 4, 2006, it was not from a snake bite. A ray’s barb on Batt Reef in Australia pierced his heart, causing him to bleed to death. Unlike snakes, rays are not considered to be dangerous animals, but nobody has challenged us on why God created rays.

Baikal Seals Are Unique

The world’s only exclusively freshwater seal is the Baikal seal (Pusa sibirica), which is found only in Lake Baikal in Siberia. This earless seal is relatively small, with a maximum of about 5 feet long. Lake Baikal is the deepest lake on Earth. It has a depth of over 5,000 feet and more freshwater surface area than all of North America’s Great Lakes combined. Lake Baikal is covered with ice most of the year, and the ice thickness can be several feet. Adult Baikal Seals can hold their breaths for up to 30 minutes, but their pups can only go a maximum of 15 minutes.

Researchers are amazed by how the pups survive. Female Baikal seals raise the pups on their own, digging a den under the ice. Some freshwater springs in Lake Baikal maintain holes in the ice. Adult seals use the holes to get air. After breathing in air, the female will go near her pup and blow bubbles to create an airspace under the ice. Pups live and breathe in that airspace and exercise by expanding the den with a maze of tunnels but never breaking the surface.

Lake Baikal is on a geological structure with no connection to any ocean. The primary food source for Baikal seals is golomyanka fish that live only in Lake Baikal. Researchers estimate that 80-100,000 Baikal seals live in the lake, as well as other unique species not found elsewhere. The evidence shows that every nook and cranny of God’s creation has life specifically designed to survive and prosper in that environment.

Baminornis Zhenghensis Fossil

Baminornis Zhenghensis - Ancestor of Modern Birds?

For many years, the scientific community has held that Archaeopteryx was the first bird. Most textbooks maintain that it was a crow-sized half-bird and half-reptile found in Germany in 1861. Archaeopteryx had a very long tail, teeth, and wing hooks or clawed hands resembling some dinosaurs. Now, researchers in China have announced they found a fossil called Baminornis zhenghensis that is more like modern birds.

The Baminornis zhenghensis fossil was found 5,500 miles away from Archaeopteryx. Dr. Min Yang of the Chinese Academy of Sciences says it had a short tail, which is critical for flight compared to Archaeopteryx’s long tail. The tail’s bone structure is made of fused vertebrae, allowing for fan-shaped feathers, which improve flight.

There are many problems involved in this find. The Baminornis fossil lacks a skull, so researchers are guessing at the tooth structure. Both specimens are morphologically advanced, suggesting a common bird ancestor. In the biblical account, God said, “let birds multiply on the earth” (Genesis 1:22). The Bible doesn’t tell us when God created birds or what they were like. Baminornis zhenghensis was small, only about six inches long, and Archaeopteryx was slightly larger.

Much about the history of life on Earth that the Bible does not tell us has been revealed in the fossil record. The information we find shows agreement between science and the Bible. We maintain that science and faith are friends. The fossil record is incomplete, just as the biblical record is. Birds have a high body temperature and all the equipment they need to fly, but we don’t see that in other life forms. New chapters will be added to the fossil record as more fossils are found, but they will only add to what the Bible has revealed.

Polar Bear Design Features

Polar bear design features enable them to live in a region of incredible cold. Previously, we reported that polar bear fur is hollow, providing insulation and creating an optical effect that looks white. New research by Norwegian nanophysicist Bodil Holst has shown how a polar bear can climb out of freezing water and then walk around in temperatures as low as minus 40. It has nothing to do with its fur, but because the polar bear has glands in its skin that secrete a grease resistant to freezing called sebum.

The skin of mammals, including humans, secretes sebum that makes hair greasy. Tests of other forms of sebum have shown that only polar dear sebum has the properties that keep the fur from freezing. At the same time, it lacks squalene that makes ice stick. There is great interest in this discovery not only from scientists but also from industries. It can potentially replace toxic de-icing chemicals used in ski wax and for plane de-icing.

Humans have benefited from many things copied from animals and plants. Common examples include Velcro (thistles), airplane design (bird wings), and synthetic fibers (spider webs). Polar bear design features are among the unique designs we see in the living world. They are not accidents but deliberate designs by a Creator, allowing life to thrive everywhere on planet Earth. As with polar bears, animals and plants usually have more than one specialized design feature.

Freshwater Mussels and Design

Humanity’s war with pollution has a surprising helper in freshwater mussels. They are susceptible to any change in the water in which they live. When anything disturbs the quality of the water, these mussels close their shells. In Poland, fifty water processing plants use these mussels to monitor any contamination of their drinking water. Technicians attach sensors to the mussel’s shells with hot glue. When four of the eight mussels close their shells, they trip a sensor alerting control computers to shut off the water supply. After three months, the mussels are removed from service and returned to the wild because they adapt to water quality and become less sensitive.

When Joe Kramarz sent this information, I thought it was a joke, but it’s true, as the National Institutes of Health reported. Our thanks to those who send us information we might miss. In this case, we find it interesting that mussels are designed to avoid pollution in their environment. Freshwater mussels are just one example of many animals that monitor their environment, including bats, whales, corals, moles, and even groundhogs. Some of these may not directly benefit humans, but they help us understand that God has designed animals for a complex and changing world.

When God challenges Job’s understanding in Job 38-41, He refers to many things in the creation that show wisdom and design. We are still learning about many of those examples, but all of them are beyond human capacity to duplicate.

Animal Coprophagy – Recycling Poop

One aspect of design in the natural world is that virtually no food goes to waste. To that point, researchers have discovered many instances of animal coprophagy, poop eating. A study published in the journal Animal Behaviour documents 150 species of animals ranging from adult black bears to baby koalas recycling poop.

Many of the animals could not survive if they didn’t eat the feces of other animals. One example is pikas, small mountain-dwelling mammals on the Tibetan Plateau. They could not survive the harsh winters if they didn’t eat the droppings of Yaks. Blind cave fish can’t leave the cave to forage for food, so they survive by eating the guano of bats that inhabit the caves. Cows have multiple compartments for processing food, but rabbits do not. Rabbits and other small animals survive by eating the droppings of larger animals that have eaten harsh foods, breaking them down to a form the rabbit’s gut can easily absorb.

You might think that animal coprophagy would lead to diseases and parasites, but the nutrition gained vastly exceeds the possible infection for many animals. Capybaras eat their own feces, so you can’t call it waste. An interesting fact is that lab rats eat up to 40% of the poop from other rats and even themselves. If lab workers prevent them from doing that, they become sick from vitamin B12 deficiencies. Insects such as dung beetles survive on animal dung.

Recycling poop gives evidence that God designed the animal world so food is not wasted. Meanwhile, humans are guilty of wasting food, leaving many people to starve. That is why Jesus Christ, in Matthew 25:35-46, told His disciples to give food and drink to those who are hungry and thirsty.
