God Has Used Animals to Teach Humans

Rattlesnakes are among the world’s most misunderstood animals. Bible skeptics refer to Genesis 3:1, saying that they don’t want to believe in a God who would create something as evil and useless as snakes. The passage reads, “Now the serpent was more crafty than any of the wild animals the Lord God had made.” Although He does not create talking snakes, God has used animals to teach humans.

The Bible has many stories of animals conveying a message to humans. Numbers 22:28-33 records a talking donkey redirecting Balaam. In 2 Kings 2:23-24, a group of teenage thugs who mocked the prophet Elisha were attacked by bears. In Jonah 1:17, we read that “the Lord prepared a great fish to swallow Jonah” to set him in a different direction. No matter what you make of those stories, animals that do terrible things to humans are not functioning normally. They are designed for a purpose, not to do horrible things to humans.

So, what possible value is there to rattlesnakes? They are designed to maintain environmental balance by controlling rodents of all kinds. A rattlesnake has a scent-detecting vomeronasal organ in the roof of its mouth, allowing it to smell a mouse or a shrew. In addition, a heat-detecting organ in the pits between its eyes and nostrils enables it to “see” a rodent in total darkness underground. This equipment is designed to eliminate small rodents, not humans.

The total number of people in the United States who die from venomous snake and lizard bites is five, according to the Centers for Disease Control and Prevention. Dog attacks kill many times more people than snake bites. Rattlesnakes have a warning built into their design that they use when threatened. I have personally been in situations where I have seen a rattlesnake within easy striking range of a human being that simply stayed in a striking position and never moved. Snakes do not want interactions with humans and are most abundant in environments humans do not frequent.

One interesting modern value to rattlesnakes is that medical researchers have found hundreds of proteins and enzymes in their venom that block or neutralize pain pathways, offering an alternative to highly addictive opiates. The venom also can dissolve blood clots and lower blood pressure. Snakes are victimized and denigrated, but they are not evil, and they are designed for a purpose. God has used animals to teach humans.

The Animal Understanding of Death

What do animals understand about death? That question has become such an area of interest that it has a name—comparative thanatology. Dr. Susana Monso has written a number of books and articles on the animal understanding of death, with special attention to opossums and chimpanzees. In her books, Monso provides information about the physiological changes in the opossum when it “plays dead.”

In a Time magazine article, Dr. Monso gave accounts of animals dealing with death. She told of a newborn albino chimp that other chimps were afraid of. When the dominant male killed the baby chimp, the behavior of the chimpanzee troop changed dramatically to a display of curiosity. Other cases cited are an orca who carried her dead baby over 1000 miles for 17 days and a gorilla who was weaned but attempted to suckle from its dead mother’s breast.

Dr. Monso argues that the animal understanding of death differs from human understanding. She says our human bias affects our view of comparative thanatology, but she believes animals understand death in their own way. Are the chimp, orca, and gorilla displaying grief, or are we interpreting them in light of what humans would feel and do? Do carnivores have empathy for the herbivores they eat? Those questions reflect what Dr. Monso calls an intellectual anthropocentrism bias.

That bias is reflected in some humans who refuse to eat meat because they feel empathy for the animal that died. To suggest that you won’t eat anything requiring death means you won’t eat anything. If you eat a plant or the seed of the plant, something has to die. Death is part of the design of life, and life would be impossible if nothing died. Either everything would die of starvation, and Earth would become devoid of life, or animal populations would overfill the planet.

The biblical understanding is that the Creator of life gave humans a special place in the creation. In Genesis 9:1-3, God tells Noah that all animal life would have the fear of humans and that humans would be responsible for managing all of life. Verse 3 also equates animal life with plant life. “Every moving thing that lives shall be food for you just like the green plant – I have given you all things.”

God gave only humans the ability to comprehend life after death. Animals’ understanding of the death of one of their kind is rooted in survival. We see this in the biblical discussion of this subject and the evidence available to all of us.

Grounded Running in Birds

Have you ever chased after a bird? Trying to catch a gull or a robin is an exercise in futility because birds can run at very high speeds. In our part of the world, we have a bird called the Killdeer, which lays its eggs on the ground in the open. As a teenager, I would chase the adult birds, thinking I could catch one, but I did not realize they were running on the ground to lead me away from their nest. I never thought about why I could never catch one because I would run out of breath before the bird would. Researchers have studied what they call “grounded running” in birds.

When humans are in a hurry, they use what is called “aerial running,” in which we pick up our feet. In grounded running, birds always keep one foot on the ground. Keeping a foot on the ground consumes less energy than human aerial running. Dr. Armita R. Manafzadeh of Yale University says that even though grounded running may look funny, “It’s actually a pretty smart thing to do when you have the anatomy of a bird.” According to Dr. Manafzadeh, “If we try to interpret the diversity of animal locomotion through a human-centric lens, we’re going to miss out on lots of really cool and equally viable ways of moving around the world.”

It is only through modern technology that we have been able to study the ground running of birds. What appears to be a silly-looking strategy is a beautifully designed system that meets the bird’s needs. The more we learn about the design and wisdom displayed in the creation, the more we see the wisdom and creativity of God.

“But ask the beasts, and they will teach you;
And the birds of the air, and they will tell you;
Or speak to the earth, and it will teach you;
And the fish of the sea will explain to you.
Who among all these does not know
That the hand of the Lord has done this,
In whose hand is the life of every living thing,
And the breath of all mankind?” (Job 12:7-10 NKJV)

A System Benefiting Birds, Ants, and Trees

Birds have an interesting method for keeping ants out of their nests and away from their eggs and chicks. Many ant species will eat everything in their path, and often, ants infect trees where birds build their nests. From a design standpoint, how can you build a system benefiting birds, ants, and trees?

Scientists have discovered that in tropical and subtropical areas, birds use fungal organs known as rhizomorphs to build their nests. Rhizomorphs are cord-like filaments that fungi use to capture nutrients, and they grow web-like in the canopy of tropical forests. These filaments repel ants to keep them out of the birds’ nests. Researchers have found that over 176 bird species use fungal rhizomorphs in their nests. Two bird species in Costa Rica build their nests almost entirely using rhizomorphs of horse hair fungus (Marasmius).

Researchers in Costa Rica found a symbiotic relationship between thorn acacia trees and ants. The ants collect nectar from the acacia, repel any invaders, and even trim back encroaching plants. The thorns of the acacia protect the ants from predation, and the rhizomorphs protect the birds. This complex system benefiting birds, ants, and trees is very difficult to explain by any chance process. The concept of God building a system that protects all three participants is simply an argument for His existence.

Macro-World Micro-World

We live in a macro-world in which we see and touch large things. Most of us don’t recognize there is a micro-world made up of very small things. Without the small things, the large things could not exist. The most obvious example of the need for small things is the food that animals need to survive.

Food chains start with the very small. Carnivorous insects that don’t eat plants provide the starting point for food chains. As technological tools become available, scientists discover more and more small animals, even some that are vertebrates. One example is the discovery of tiny Brachycephalus pulex frogs, also known as Brazilian flea toads, because they can jump 30 times their body length. They are only 7 millimeters (.3 inches) long, and unlike other frogs, they don’t go through a tadpole stage. Their eggs hatch directly into tiny frogs.

Scientists have found tiny animals in desert environments providing a basis for life in what would appear to be a sterile environment. Tardigrades, known colloquially as water bears or moss piglets, are another example of very small creatures that are important agents for life in the macro-world.

Many plants and animals that allow life to exist are not perceived through our senses. Everywhere we examine the macro- or micro-world, we find a design created by God. Romans 1:20 tells us, “..the things of God which the eye is unable to see ever since the world was made are clearly perceived through the things that are made.” The things we can’t see include the spiritual things of God and the small things in the material world as well.

Humuhumunukunukuapua’a

Hawaii’s state fish is the humuhumunukunukuapua’a. The scientific name is Rhinecanthus rectangulus, but people call them humuhumu for short. This is a species of triggerfish, and the design complexity of these fish defies any chance formation.

The name Humuhumunukunukuapua’a means “a triggerfish with a pig’s snout.” These fish eat lobsters, sea urchins, and snails. They can blow water jets from their mouths to find these foods under sand. The triggerfish name comes from having a “trigger” that locks their dorsal fin in the up position to prevent a predator from extracting them when they hide in a small crevice.

A four-bar linkage mechanism links the humuhumu’s skeleton to its jaws. That gives it a powerful mechanical bite needed to capture its hard-shelled prey. Engineers study the humuhumu to see how humans can assemble and use such structures. This bone-cartilage mechanical linkage defies any step-by-step evolutionary assembly process, and there is no evolutionary precursor to triggerfish.
Like all the examples of design in the natural world, the humuhumunukunukuapua’a strongly supports the biblical statement that we can know there is a God through the things He has made (Romans 1:20).

Blind Cave Fish Find Food

How is bat guano controlled in caves, and how do blind cave fish find food? Like all natural balances, there is a relationship between these two questions.

With vast numbers of bats in caves, over many years, their droppings could fill the caves if there were no natural ways to reduce the volume. Dr. Josh Gross at the University of Cincinnati has discovered that blind cave fish actually eat bat guano. It provides food for the fish, which would otherwise have nothing to eat.

What the fish get from the guano depends on what kind of bats live in the cave. Fruit bats will have some sugar in their guano, and bats that eat insects will have some protein in theirs. The next question is, how do the fish find the guano that will nourish them? The answer is that the fish have taste buds under their chin and on top of their heads.

The fish avoid destructive bacteria that might be in the guano because some of the taste buds can detect lactones in the bacteria that would taste bitter. These taste buds are called tuft cells, and in addition to harmful bacteria, they can detect dust mites and mold.

Everywhere we look in the natural world, even in the darkest caves, we see God’s design and handiwork, even in how blind cave fish find food. Romans 1:20, “We can know there is a God through the things He has made,” has special meaning when we see examples like this.

Termites Building Heuweltjies

The more we learn about insects, the more we see design and purpose in their creation and survival methods. Researchers recently studied termites building heuweltjies (“little hills”) in South Africa and Nambia. These termite mounds cover labyrinthine tunnels and chambers that extend 11 feet underground. In addition to their size, they are impressive for their age, with various dating methods showing they are up to 34,000 years old.

These termite colonies have survived for a long time because they are covered with a hard layer of calcite that their main enemy, Aardvarks, cannot penetrate. Termite soldiers and workers go into emergency mode to repair any damage caused by the researchers studying them. The same defensive action would be activated to quickly reseal any break in the calcite layer caused by an aardvark predator. The soldiers guard the tunnels while the workers repair the breach.

In the natural world, termites perform essential services. Termites building heuweltjies break down plant material, producing topsoil, sequestering carbon, and reducing erosion. In some parts of the world, such as Australia, it is virtually impossible to use wood in construction because of termites’ actions. However, termites play an essential role in areas where human structures are not involved.

We sometimes struggle over conflicts with insects, but they remain successful because God designed them with functions and protections to survive. The termites building heuweltjies in South Africa and Namibia are a classic example.

Eagle Eyes and Design

Eagles are some of the most amazing creatures in today’s world. We are familiar with bald eagles and golden eagles, but there are eagles everywhere on Earth, and they have similar designs. Eagle eyes are incredible examples of design that is not easily explained by any chance hypothesis.

The human eye has two kinds of receptors in the retina – rods and cones. Rods are more sensitive and give vision in dim light. Cones provide us with color vision. We don’t see color in dim light because only the rods are sensitive enough to function. Cones are concentrated in the center of our retina in an area called the macula to help us see fine details.

A typical section of the human eye has roughly 200,000 cones, while eagle eyes have over 400,000. That means an eagle can see fine details that the human eye cannot detect. The reason for this design is obvious. Eagles are carnivores, and to see their prey while in flight, they must have incredibly sensitive vision. Experiments with pet eagles have shown they can see a rabbit in a field while flying 1000 feet above the ground.

The problem with this sensitivity is how to keep direct sunlight from damaging the cones. To solve this problem, eagle eyes are protected by an eyebrow ridge that shades the cones. All eagles have this feature and use it in hunting their prey, including small mammals and fish, which are a mainstay of the diet of most eagles.

Eagles are designed to be apex predators. They are the perfect carnivores with talons to grasp prey, wing feathers that allow amazing flight abilities, and powerful wings to lift heavy prey. Eagles keep a balance in nature and are essential in the stability of life forms worldwide.

Superstar Lucy and Anthropology

American Scientist magazine called Lucy “Paleoanthropology’s Superstar.” Lucy (Australopithecus afarensis) is a hominid fossil found in 1974. Paleoanthropologist Donald Johanson named it Lucy because the Beatles song “Lucy in the Sky with Diamonds” was being played on the radio that year. Lucy had a brain size of 450 cc. A modern human’s brain is between 950 cc and 1800 cc, depending on sex and location. What is special about superstar Lucy?

Lucy stood about three feet seven inches tall, weighed around 60 pounds, and had a pelvis similar to a chimpanzee. Lucy’s limbs were close to the ratio of a monkey, with the femur and humerus being about the same size. In humans, there is a 2:1 ratio between these two bones. The opening into the skull through which the spinal column sends its messages to the brain is called the foramen magnum. In a human, that opening is centered in the middle of the skull, allowing a normal vertical position. In a monkey, the foramen magnum is in the back of the skull, so vertical standing is difficult. In the case of Lucy, the foramen magnum is not in the center of the skull and not in the very back of the skull. Vertical motion and standing would have been possible, but walking long distances would be difficult.

Graduate students and anthropologists have used superstar Lucy for fundraising, with many getting support for field research. In the 50 years since Lucy’s discovery, researchers have found many other hominid fossils in better condition than Lucy. The theory of human evolution 50 years ago was a tree with something like Lucy at the base. The newer models are that hominoid history is more of a bush than a tree.

So, where do Adam and Eve fit into all of this? The Bible says that man was formed “from the dust of the Earth … and man became a living being”. The Hebrew used here is “nephesh,” which the Hebrew lexicon says means “animal soul.” The passage does not say how long God took to do that or what process He used. We can understand some of what God did by looking at the fossils. What separates the first human is not his body. Our body chemistry is the same as other forms of life. What sets us apart is our creation in God’s image.

Genesis 1:26-27 describes the unique creation of man – not his physical body. “Let US create man in OUR image” refers to the Father, Son, and the Holy Spirit.” In other words, the image of God refers to our spiritual makeup. It isn’t our brains or our bodies that make us unique and special. All humans are created in God’s image with a spiritual aspect that can last eternally. The physical body will return to the dust from which it came (Genesis 3:19), but our spiritual body (soul) is not subject to the physical laws that govern all other life on Earth.

As anthropologists focus on superstar Lucy, The big question is, “When will we recognize the unique beauty of all humans and stop killing each other?”
