The Bearded Vulture – A Bone Eater

The bearded vulture is a large bird found in mountainous areas of southern Europe, Africa, and Tibet. It is known in some areas as the lammergeier or ossifrage. However, it is also known for the fact that it deliberately uses mineral-rich dust and mud to dye its feathers red for reasons still unknown.

Our interest in this bird is centered around its diet. This bird eats bones. When it finds a dead animal, the bearded vulture will drag out a large bone and carry it several hundred feet in the air and drop it on some rocks, smashing the bone into smaller pieces. The bird will then pick up the pieces, one at a time, and swallow them. The bearded vulture apparently has the strongest stomach acid in the animal kingdom. The bones they digest supply all the minerals and vitamins the bird needs to survive.

A program called “Snow Wolf” on the BBC included a section on bearded vultures because they follow wolves in the mountains. When the wolves make a kill, the bearded vulture will wait until the wolves have eaten all of the meat. Then they will start picking up the remaining bones to eat them.

The BBC broadcasts various programs on the unique living things that exist on planet Earth. While the BBC is not sympathetic to any kind of religious concept, many of the stories they present show evidence of design in the creation. One fact about the world in which we live is that in the natural world, nothing goes to waste. Even hard materials like bones are disposed of in some way. The bearded vulture provides one way bones are recycled. We need to learn how to return human-created waste materials to the environment from which they came without polluting it. Ultimately our survival will depend on doing that.

Cassowary – A Strange Bird

When we think of birds, we usually picture songbirds, chickens, pigeons, eagles, and others. However, we are also aware of less familiar birds such as penguins, ostriches, and kiwis. Imagine a bird that stands up to six feet (1.8 m) tall, weighs 130 pounds (59 kg), has spine-like quills in place of feathers, and has a four to five-inch (12.5 cm) claw on its inner toe that it can use to stab and even kill a dog or a human. This creature can run 30 miles (50 km) per hour and jump more than five feet (1.5 m) in the air. The name of this bird is the cassowary.

These birds, native to New Guinea, Indonesia, and Australia, can kick, stab, head butt, and peck. Cassowaries are a factor in the discussion of whether the dinosaurs were birds or reptiles. The wings of most modern birds are for flying, or in some cases, for swimming underwater. Instead of feathers, cassowary wings are tipped with large quills resembling porcupine quills without the barbs. Some dinosaur fossils give evidence of feathers, but we don’t know their function. However, cassowaries demonstrate that wing-like and feather-like structures can have other functions.

The cassowary can teach us many lessons. One is that taxonomy gives us only a limited view of various animals. Another is that birds have more than one role in ecological applications. Cassowaries play an essential role in the ecosystem where they live. They are omnivores, eating fruits as well as small animals. They lay eggs in a nest on the ground and incubate the eggs. The males are the primary caregivers during incubation, and they care for the young after the eggs hatch. We tend to view flightless birds as vulnerable creatures that live only where there are no predators to threaten them. Cassowaries show us that is not always true. They can defend themselves and live for 40 to 50 years.

The biblical view of birds includes only birds that could fly. The Hebrew word commonly used for “bird” in the Old Testament is “tsippor,” meaning a small bird, such as a sparrow. (For example, see Genesis 7:14 and 15:10, and Ezekiel 39:4.) The Hebrew word “oph” refers to a flying bird. (For example, see Genesis 40:17-19, 2 Samuel 21:10, Ecclesiastes 10:20, and Hosea 9:11). “Ayit” refers to a hawk or bird of prey. (See Isaiah 46:11 and Jeremiah 12:9.) In the New Testament, the Greek word “peteinon,” meaning flying or winged bird, is used in Matthew 8:20 and 13:32, Luke 9:58, Romans 1:23, and James 3:7.

The Cassowary does not fit any of those passages, considering that people in the world of both Moses and Jesus did not have contact with flightless birds. Instead, we can view the cassowary as a part of God’s creation to fill a very different kind of ecological ni che. However, its role in creation’s design and the world today remains a subject of future study.

Animals Growing Crops

We generally think of farming as a human enterprise, but there are cases in the natural world of animals growing crops. In most cases, the crop they are raising could not survive without the animal tending it. Some good examples are living things that eat fungi or algae.

Researchers at Kyoto University in Japan studied red algae called Polysiphonia. These algae have a symbiotic relationship with a species of damselfish (Stegastes nigricans). Red algae look like a brown carpet, and the damselfish make sure that the carpet is not disturbed. If any other species of algae shows up among the red algae, the damselfish will nip it off and take it out of the fish’s territory. If the damselfish is removed from the area, the red algae can’t survive. So it appears that the damselfish are critical to the survival of the red algae and vice versa.

There have been other studies of certain species of ants, termites, and ambrosia beetles that grow fungi for food. Some of these “farmers” even use bacteria to produce pesticides to protect their fungus crops. How do such symbiotic relationships happen? Evolutionists suggest that initially, the animal had a varied diet but becoming dependent on one thing offered such an advantage that the animal gave up any other foods.

The difficulties with the evolutionary explanation are many and quite complex. The nutritional issues are a problem because a single source of nutrition must have a balanced collection of minerals. Going from a varied diet to a single food does not seem to be an evolutionary advantage. Defending the food source is also an issue. For example, when the researchers removed the damselfish, other fish and sea urchins had eaten all of the red algae within days.

Another explanation is that symbiotic relationships are part of the design of every animal’s genome. The earliest fossil remains of many animals show that a symbiotic relationship was already in place. We suggest that animals growing crops is part of God’s design. He gave them the genetic messaging and instinctive drive necessary for them to survive.

Design of Deer Eyes

One of the most compelling examples of God’s design in the world around us is the design of eyes. The eyes of every creature on Earth are specially designed to allow the animal to survive. The retinas of our eyes contain three kinds of color cones sensitive to red, blue, and green. When all three cones work together, our brain tells us that what we are seeing is white. However, the design of deer eyes is different.

Very few animals have all three types of cones, and this design allows animals to maintain a balance in the natural world. A PBS documentary called “Nature” carried a discussion of how predators control deer in the natural world to prevent their population from exceeding the food supply. In North America, wolf packs kept the deer population under control. However, now that wolves have been removed, many of us are plagued with over-populations of deer.

Several years ago in southern Indiana’s Brown County State Park, hunters were allowed to cull the deer population. Some 12-year-old deer weighed only 60 pounds, and vegetation in the park was threatened. When older trees died, the park’s abundant tree population was threatened because deer were eating the young ones.

In other parts of the world, tigers keep deer populations in check. How can a large orange-colored animal ever catch a deer which can easily outrun a tiger? The answer is that a deer’s eye does not have any red-sensitive cones, so the deer does not see the orange color of the tiger. A tiger can get very close without the deer seeing it, so the tiger is wonderfully camouflaged to control the deer population.

We need to be careful not to let “Bambi” demean our appreciation of predators in the natural world. In places where the deer population is out of control, the ecological system can collapse. For example, we have so many deer here in Michigan that those of us with gardens, decorative bushes, and trees have to constantly spray deer repellant to keep our plants from being eaten. God’s design avoided that problem until humans threw it out of balance. The design of deer eyes is part of that balance.

Autoimmune Diseases and God’s Design

“Autoimmunity is the system of immune responses of an organism against its own healthy cells, tissues, and other body normal constituents. Any disease that results from such an aberrant immune response is termed an “autoimmune disease.” –Wikipedia

As many as 4.5% of the world’s population may be affected by any of about 80 autoimmune diseases. Some such as psoriasis are cosmetic, and others such as multiple sclerosis are life-threatening. So when the human body attacks itself, should we assume that it is because the body’s design is flawed? The exact cause of autoimmune disorders is unknown, but as more and more data becomes available, it is clear that this is not a flaw in the design of the immune system.

First of all, the number of autoimmune disorders that affect large populations is minimal. Psoriasis, Hashimoto’s thyroiditis, celiac disease, Graves disease, and rheumatoid arthritis are the most common, affecting one person out of every 100. Type 1 diabetes, vitiligo, and rheumatic fever can affect one person out of every 1000 or so. Most autoimmune diseases are infrequent, with some affecting fewer than 1 in a million people.

Secondly, we now know that some bacteria or viruses entering the human body from animals may confuse the immune system and lead to disorders. COVID and AIDS have shown us that animals are a source of viruses that can cause disease in humans.

Thirdly, chemicals can trigger changes in cells that the immune system is not designed to handle. Pesticides, herbicides, recreational drugs, industrial waste, and medical waste have caused all kinds of problems for humans. Immune disorders may not be because of bad design of the immune system but the result of human ignorance, carelessness, and greed.

Fourth, a new study has suggested that stress may lead to some autoimmune diseases, such as lupus or rheumatoid arthritis. There is a higher incidence of autoimmune diseases among people who were previously diagnosed with stress-related disorders.

God’s design of the human immune system is amazing. As the Psalmist said. “I am fearfully and wonderfully made” (Psalms 139:14). The immune system that allows most of us to live for many years with good health is one of the best demonstrations of the truth of that statement.

— John N. Clayton

See the September 2021 issue of Scientific American (pages 26-51) for much more information about autoimmune diseases, their causes, and potential cures. Pages 32 and 33 display a fascinating chart with data on 76 autoimmune disorders.

Plants use Magnetism

One area of constant scientific investigation is the involvement of magnetism in living things. Studies have shown that cattle can align themselves with Earth’s magnetic field. Magnetism seems to be used by some animals in migrations. The presence of magnetism in the human brain has led to research into what that magnetism does and how medical science can use it to treat certain diseases. In addition to animals, plants use magnetism.

Scientists have found that magnetism plays a role in the survival of some plants. For example, the Venus flytrap uses jaw-like leaves to trap insects. Scientists have been mystified by what causes the “jaws” to close. However, it appears that stimulation from prey produces a small magnetic field which triggers the “jaws” to snap shut.

Studies have shown that other plants use magnetism by generating magnetic fields, including a bean and a single-celled alga and bacteria. This magnetic ability seems to be built into the plants for highly specialized functions. Thus, God’s design for every living thing is both subtle and complex.

Science is just beginning to understand how plants use magnetism. As we have said before, that Earth’s magnetic field has reversed in the past. We are far from understanding the many ways such a reversal could have affected life on this planet.

Realize that magnetism in a living plant requires ferromagnetic materials to be built into the plant. Those magnetic materials would serve no other purpose than to allow the plant to use magnetism somehow. Everywhere we look in the natural world, we see that a wonder-working hand has gone before.

Upside-Down Beetle Walking Underwater

The insect world continually surprises scientists who sometimes see an insect do something that no one had noticed or paid attention to before. For example, most of us have witnessed water striders that use surface tension to skate along the top of quiet pools of water. However, recently a researcher in Australia noticed a beetle walking on the water surface, but upside down from below. The upside-down beetle is a species of water scavenger beetle (Hyrophilidae) and the first beetle in which a scientist has documented this behavior.

Some snails can slide along the underside of the water surface on a layer of mucus. However, these beetles seem to have a unique method of walking upside down in the water. They can even stop and pause or change directions as if walking on a solid surface. This gives the beetle some advantage to avoid predators.

This behavior was noticed and documented by behavioral biologist John Gould of the University of Newcastle in Australia. The picture is of another water scavenger beetle in Ohio. However, you can see a video taken by Gould on YouTube at THIS LINK.

Apparently, the beetle traps an air bubble against its upturned belly, allowing it to press against the water-air boundary. The beetle’s feet must have some way of getting traction to enable movement. Robotics experts have learned from the ability of water striders to walk on the water’s surface. Therefore, it seems likely they will find some uses for walking upside down under liquid surfaces.

Gould said that “the findings about the upside-down beetle highlight how often we ignore or miss the amazing things the smallest animals are doing every day, and describing the natural history of the small is just as important as describing the natural history of any large mammal or bird.” In addition, the upside-down beetle reminds us that we can learn by studying God’s creation and the design He built into every living thing.

Cruel Deaths of Animals

One of our regular readers has raised a good point about our discussion of why predators are essential to the survival of life on Earth. He said, “Your article reasoned why there must be predators: ‘to keep nature in balance.’ But that doesn’t answer the question. It was ‘why must animals undergo such cruel deaths?’”

The question of “cruel deaths” raises many issues and assumptions. We tend to assign human values to animals and assume they have the same feelings and emotions we have. This complicates the question and causes responses that are not consistent with the evidence.

The phrase “cruel deaths” is the real issue in this discussion. Has God designed anything in animals that reduces the pain animals perceive in being killed? First, we need to understand that there is a difference in the physiology of different kinds of animals. All animals have a nociception response to pain. You have a quick response when you touch something hot. It is essentially a reflex response to pain. It is obvious that to avoid a negative sensation, animals must know when something is injuring them.

The real issue is pain that comes about by some other means. Only primates, including humans, have a neocortex area in their brain in which we can realize the sensation of pain. The neocortex receives signals from group C nerve fibers, allowing pain sensations to travel from an affected area to the brain. In humans, nerve fibers connect 83% of the body’s extremities to the neocortex area. On the other hand, fish have only 5% of the group C nerve fibers, and they are smaller in diameter, meaning that there is a low nerve conduction velocity. The bottom line is that animals do not feel pain as humans do. Another interesting fact is that animals have an instinctive drive to eat food containing analgesics (pain-killing substances).

We have to understand that it is a delicate balance to design an animal with the necessary nociception response to pain required for survival without having a neocortex response to pain. We can’t imagine the pain of having our stomach torn open by a predator, but even for humans losing a lot of blood, leading to death may not be a painful experience.

It is easy for humans to criticize the Creator’s design of an animal until we try to design one ourselves. What God has done is to build living things, so they do not suffer in the way humans do. We must be careful to avoid anthropomorphizing animals—thinking of them in human terms—suggesting cruel deaths.

Data for the above came from a variety of websites in a search for “animals and pain.”

Glasswing Butterflies – Practically Invisible

We often overlook how hard it is to maintain the balance between different kinds of life in the natural world. For example, if an animal is too successful at avoiding predators and reproducing, it will eat up all of its available food. If it is not successful enough, it will become extinct because predators will wipe it out. Then the predators will be short of food. The design of life which allows animals and plants to exist in balance with their environment is amazing.

One design factor that protects many animals is camouflage. An excellent example of that is an insect known as glasswing butterflies (Greta oto) which have transparent wings. One scientist said that “transparency is the ultimate form of camouflage” because the insect can blend into any background, but transparency is “really hard to do.” Glasswings live in the rainforests of Central and South America.

Most living things are visible because they reflect light. However, microscopic studies of glasswing butterflies show that the wing material has low absorption, low reflection, and low scattering of light. Microscopic nanopillars on the wing’s surface are designed to minimize light reflection and smooth the refraction index gradient between the wing surface and the air. The result is a practically invisible wing except for the dark brown borders tinted with red or orange.

If you believe that natural selection is the sole cause of this design, why don’t all butterflies have transparent wings? This feature obviously favors the survival of the butterfly. Most butterflies have colorful, eye-catching wing patterns that make them visible while giving us an appreciation for the role of beauty in the creation.

From an evolutionary standpoint, there should be no butterflies left with colorful wings, but glasswing butterflies are the exception, not the rule. God has designed creatures to survive in all kinds of environments.

Missile Defense Systems and Dragonfly Brains

Researchers at Sandia National Laboratories have been studying the brains of insects to learn how to build computers that can intercept incoming missiles. Dragonflies successfully capture up to 95% of the prey they pursue – which is usually mosquitoes. The dragonfly doesn’t just aim its body at the mosquito, but rather it points its body at where the mosquito is going to be. You can see the connection between missile defense systems and dragonfly brains.

Dragonflies have specialized eyes that send data to their brains at the equivalent of 200 frames per second, which is several times faster than the human eye. The human brain has many more neurons than the dragonfly–86 billion as opposed to the 250,000. The larger number of neurons in human brains allows us to have cognition and do many things. However, dragonflies are designed to do one thing—to catch their food—and do it fast.

Dragonflies respond to a maneuver by their prey in 50 milliseconds (ms). That requires the eye to detect and transmit information to the brain in 10 ms. The brain has to calculate the dragonfly’s counter-maneuver in 35 ms to leave 5 ms for flight muscles to activate and take the dragonfly to where the mosquito will be. In-flight, the dragonfly must continually monitor the mosquito’s path and recalculate the trajectory. The speed of the process means there is time for only three or four neuron layers to act. Missile defense systems and dragonfly brains must act quickly.

Other insects have neurons designed for specific functions. For example, monarch butterflies have a navigational system that depends on the position of the Sun. Since the Sun’s position changes from morning to afternoon, the butterflies must have a designed system that allows them to always travel in the right direction. In addition to that, they need an instinct that tells them when to start their journey. Ants and bees also have neuron structures that allow them to return to their nest or hive no matter how far they get from it in their search for food.

Researchers at Sandia National Laboratories and Janelia Research Campus are studying these insect brains with the idea of building computers that will allow interception of missiles, prevent cars from colliding, and serve other practical purposes that require focus and speed. Proverbs 6:6 tells us to “go to the ant … consider its ways and be wise.” The design we see in even the simplest of God’s creatures radiates purpose and intelligence beyond that of mechanical chance.
