The Scorpion and the Mouse

Two small but fierce animals live in the Sonoran Desert of the southwestern United States and northern Mexico. One is the Arizona bark scorpion (Centruroides sculpturatus), and the other is the southern grasshopper mouse (Onychomys torridus). The scorpion and the mouse give medical science an insight into pain relief.

Arizona bark scorpions grow to barely more than three inches (8 cm) long, but their stingers pack a wallop. They are nocturnal foragers, feeding on insects, including beetles and roaches. They can live up to six years and sometimes congregate in packs. Many of them survived intact close to ground zero when the United States conducted atomic blast tests in the desert. Their venom is the most potent of any scorpion in North America, and it can be fatal to small animals, children, the elderly, or the sick.

However, Arizona bark scorpions are up against a small predator with a strong defense. The southern grasshopper mouse eats grasshoppers, centipedes, snakes, and scorpions. These mice are immune to the venom of snakes and scorpions. They also eat highly venomous centipedes, which could kill the mouse. However, this courageous mouse sneaks up and pounces on its prey like a cat.

The southern grasshopper mouse has an excellent defense against the terrible pain from the Arizona bark scorpion’s sting. If the scorpion stings humans or ordinary mice, sodium channel proteins in the skin send a painful message to the brain. However, when the southern grasshopper mouse is stung, channels block the flow of sodium, and the pain is quickly gone. More than that, researchers found that the venom injection also blocked other pain sensations for the mouse.

The scorpion and the mouse can teach a lesson to medical scientists working on pain-relieving drugs. Doctors have been trying to find ways to block human pain channels for years. The southern grasshopper mouse may have the solution if we can learn how the system works and how we can duplicate it. Science has made many medical discoveries by studying God’s design in the natural world.

Evidence for Design in Nature

On our websites, we often talk about evidence for design in nature. When average people see the amazingly organized structures in living organisms, they can’t help but feel that they must be designed. Even Richard Dawkins, the evolutionist best known for his worldwide atheism campaign, said that living systems “give the appearance of having been designed for a purpose” (The Blind Watchmaker, page 1). Of course, he adds that it is only an illusion. Atheist Francis Crick, who with James Watson, discovered the helical structure of DNA, warned biologists that they must “constantly keep in mind that what they see was not designed, but rather evolved” (What Mad Pursuit, page 138).

The intuition of design is nothing new. Plato and Aristotle saw evidence for design in nature and thought there must be a mind behind it. Of course, they could not know about the information-rich DNA molecule and the intricate structures within every living cell. They didn’t even know about cells. Even Charles Darwin thought that cells were just jelly-like protoplasm. He had no idea that there are machines, transportation vehicles, gates, duplicators, inspectors, and trash collectors within the cell wall in a city-like structure.

The more we learn about the inner workings of living things, the more we see design evidence not even imagined in previous years. Every living cell has a DNA molecule containing the instructions for building the proteins and structures required for that living creature. Computer pioneer Bill Gates wrote, “DNA is like a computer program, but far, far more advanced than any software ever created” (The Road Ahead, page 188). Even Richard Dawkins wrote, “The machine code in the genes is uncannily computer-like” (River Out of Eden, page 17).

Is there evidence for design in nature? Let me ask another question. Has any computer program ever created itself by chance, or did an intelligent mind write it? Apply that thought to the living things you see every day.

Harrier Design

The name “harrier” comes from a word that means to pillage or rob. So why are several species of hawks known as harriers? The northern harrier (Circus hudsonius) is a hawk species with a harrier design.

Northern harriers breed in Canada and the northern United States and migrate to Mexico and Central America during the winter. Their ability to “pillage or rob” comes from their long wings and tails, allowing them to fly slowly and quietly close to the ground to snatch their unsuspecting prey. They have the longest wing and tail length relative to the body size of any North American bird of prey (raptor).

Northern harriers hold their long wings in a “V” shape as they closely circle the contours of the land, ready to capture small mammals such as mice, rats, ground squirrels, and voles. Sometimes, they catch frogs or small birds. They have excellent hearing and use that to locate their prey. Farmers sometimes call these birds “good hawks” because they eliminate rodents that destroy crops and don’t bother poultry as other hawks do.

You can see the “V” shape of the wings of a harrier hawk on harrier aircraft, which were designed for short/vertical take-off and landing. A good design deserves to be imitated, and this is another example of many of God’s designs that humans have copied to create useful tools. In the harrier design, we see the work of the Master Designer.

Migration of Painted Lady Butterflies

Most of us are familiar with the incredible migrations of monarch butterflies. Until recently, scientists could not track a butterfly species migrating distances exceeding the monarchs. It is the migration of painted lady butterflies.

These butterflies weigh less than a gram, so attaching tracking devices to them is impossible. For that reason, the paths traversed by the migration of painted lady butterflies were unknown until researchers developed a tracking system involving hydrogen and strontium isotopes in their wings.

As with monarch butterflies, painted ladies make their migrations over several generations. Unlike monarchs that specialize in milkweed, painted ladies feed on numerous host plants, allowing them to migrate up to 9,300 miles annually. The migration of painted lady butterflies in Europe and Scandinavia involves traveling to Africa and back. In North America, they travel between Canada and Mexico. In Asia, they fly through the Himalayas. Painted ladies are designed to weather cold conditions with yellow fat reserves and by shivering to generate body heat. They can fly up to 30 miles per hour.

Everywhere we look in the natural world, we see examples of design showing wisdom and intelligence. The food chain would be interrupted, and life on Earth would cease to exist without insects designed to withstand all kinds of environmental factors. The migration of Painted lady butterflies is not an accident of nature, but the product of a mind that designed Earth and all that lives on it so we can be here.

Programmed to Survive – Self-Preservation Subroutine

HAL was Programmed to Survive with a Self-Preservation Subroutine

Every living organism is programmed to survive. That is a very broad statement, but let me tell you what I mean. On this website, we often describe the way God designed creatures with the defense mechanisms necessary to avoid, evade, or defend against predators. However, they are equipped with more than defense mechanisms. In computer terms, a self-preservation subroutine is programmed into their DNA. Even plants that have no brain or desires have this self-preservation quality. I’m sure you have seen this when you try to get rid of weeds in your lawn or garden.

Where does this self-preservation subroutine come from? Living things are programmed to survive by their Creator. In 1969, I was a college student in Cincinnati when the science fiction movie 2001: A Space Odyssey opened in movie theaters. The movie depicted space travel and “picture phone” communications. Space travel today has still not reached the level shown in the film, but today’s mobile phones make the picture phone booth of the movie seem primitive. I still don’t fully understand the movie’s meaning, but HAL, a computer with a self-preservation subroutine, fascinated me.

HAL 9000 was programmed to survive and refused to allow the human astronaut to disable him. That was the scary part of the movie for me. The concept of an evil computer or robot with artificial intelligence and a self-preservation subroutine endangering humans has become the plot of science fiction thrillers. Those human creations could become a modern Frankenstein’s monster. That terrifying scenario is what many fear AI (artificial intelligence) could lead to.

You can take some comfort in the fact that human programmers have been unable to design a computer program with a self-preservation subroutine. Look around you, and you will see a myriad of living things that are programmed to survive. God has programmed survival software into every living organism, demonstrating that He is far more intelligent than any human computer programmer. God’s wisdom and creative genius programmed all life to survive for a purpose.

Sea Turtles Find Food

Research has answered an interesting question about life in the sea – how do sea turtles find food? They have an extensive diet, including small invertebrates, jellyfish, and fish eggs. The problem is that these food sources are only in small patches scattered across the ocean, so how do sea turtles find them?

The answer relates to Earth’s magnetic field. Sea turtles can create GPS-like magnetic maps of Earth’s oceans. They begin to do this as hatchlings and remember the locations for years or even decades. Loggerhead sea turtles live for about 20 years, and the internal GPS map guides them to food and migration routes for a lifetime. They must begin as hatchlings because many predators can eat a baby turtle. Survival of hatchlings requires that sea turtles find food quickly and grow large enough to escape their predators.

Recent research has shown that sea turtles have two senses for detecting Earth’s magnetic field. One senses the direction of the magnetic field lines, and the other detects magnetic features to locate foraging areas where sea turtles find food and beaches where they can lay their eggs. Research has shown that migrating songbirds also possess these magnetoreception systems.

God has provided all animals with the special equipment they need to survive. We see God’s wisdom and planning everywhere we look in the natural world. As Romans 1:20 says, “We can know there is a God through the things He has made.”

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).
