Ant Farmers at Work

We commonly think of animals as opportunists. They find their food and eat it or store it for future eating. One of the characteristics of humans that distinguishes us from the rest of the animal kingdom is that we prepare an environment that produces our food. Farmers plant seeds and tend the crops by fertilizing, protecting from threats, and watering when necessary. They also make arrangements for future crops. Entomologists are finding more and more cases where insects do these same things. For example, ant farmers work together to produce their food.

In Fiji, a plant called Squamellaria grows in a cluster with jelly-bean shaped bubbles inside. The opening into the clusters is just the right size for the Philidris nagasau ant to get into the bubbles. As the bubbles send out shoots, the ants defecate inside the cluster, fertilizing the plant. When the plant blooms, the ants eat the nectar it produces. The ants then plant the seeds where new clusters can grow.

Another family of ant farmers is the Atta genus. In their farms, they grow a fungus species that they nourish with leaf cuttings. After cutting off leaf sections, worker ants carry them back to the colony. As the workers transport the leaf cuttings, others ride on the leaves to protect against a parasitic fly species. You might call that pesticide.

At the colony, other ants pulverize and defecate on the leaves to make them ready to nourish the fungi. The ants can’t eat the leaves, but the fungi are their food, and only one fungus species is edible. If another fungus species develops, the ants produce a toxin, which destroys only the invading fungus. This is herbicide use at its best. The Atta ants inspect the fungus several times a day, tending it carefully. The system is so efficient that one Atta nest can grow enough fungus food to feed seven-million resident ants. In the process, the ant colony produces fertile soil that promotes plant growth.

If you saw the 1994 Disney animated Lion King movie, you saw Atta ant farmers at work. Remember that fungi are not photosynthetic. No sunlight is needed for Atta ants to grow their food. They simply carry in the nutrients for the fungi to grow, and then they eat the fungi. We do the same thing with much of our meat, providing plant material for chickens or pigs to eat, and then eating the animals that we fed. In the case of the ants, they eat only one food, which simplifies farming enormously.

We know it takes incredible planning and design to manage a farm. No chance process produces most of the foods we eat. It requires meticulous planning and careful application of fertilizers, pesticides, and herbicides. As scientists study insect farming, they see a design that is carefully and intricately produced.

Data on the ant farmers came from Science News, April 25, 2020, pages 16-20. The subtitle of the article is, “Could our agricultural role models have six legs?” This reminds us of the challenge in Proverbs 6:6-8: “Go to the ant … consider her ways, and be wise. She has no guide, overseer or ruler but provides her food in the summer and gathers her food in harvest.” The title of the article is “The First Farmers.” We might amend that to be “God’s First Farmers.”

New Zealand Kiwis Are a Treasure

There are animals designed to fill every ecological niche, and they are often specialized for a local ecosystem. Many flightless birds have a unique ability to fill a specialized niche. Penguins and ostriches are examples of that. New Zealand kiwis are an especially odd example of birds designed for a unique environment.

These flightless, nocturnal birds fill a niche in the New Zealand forests. They are about the size of a chicken, and they eat worms, insects, and berries. Kiwi feathers resemble the rough fur of some mammals rather than bird feathers. The feathers shed dirt efficiently, which is good since they live in dug-out burrows underground. Kiwis get their name from their vocalizations, which sound like “keee weee.”

Kiwis have no keel on their sternum and no tail, so they can’t fly. They do have muscular legs with four toes. (Most flightless birds in the ratite group have two or three.) They have thick, tough skin and heavy, dense bones. (Most birds have hollow bones for flying.) They have a low body temperature for a bird. Their bills have nostrils at the tip, giving them an acute sense of smell. By eating worms, grubs, and insects, kiwis maintain the ecological balance needed in the forest. New Zealand kiwis had no predators until humans introduced dogs and cats to the country.

Kiwi eggs are designed differently from other bird eggs. They are huge, being equal to 20% of the mother’s weight. It would be like a human mother having a baby one-fifth of her weight. The eggs have twice as much yolk as other bird eggs, and they contain antibacterial and antifungal materials needed for living in underground burrows. The male sits on the egg until the chick kicks its way out since kiwi chicks have no egg tooth to break the shell. The parents do not feed the chick, which lives on the extra yoke until it can follow the male outside to get worms and insects.

God’s design is different in each ecosystem, but there are always creatures that provide balance. When humans upset that balance, the result can be a disaster. New Zealand kiwis are an example of unique specialization to support the forests of that unique country. To the people of New Zealand, they are a treasure.

Biomimicry Solves a High-Speed Train Problem

Japan has been a world leader in the development and implementation of high-speed trains. More than 10 billion Japanese passengers are transported by rail each year, and those trains keep the population highly mobile. However, biomimicry solves a high-speed train problem.

One of the major difficulties with the high-speed rail system was that the trains had a bullet-shaped nose. That design compressed the air creating a severe shock wave every time the train went through a tunnel. This “sonic boom” was especially bad in cities, and because Japan is densely populated, the sonic shock waves were a real problem.

The chief engineer for the West Japan Railway Company named Eiji Nakatsu also happened to have birding as a hobby. He was trying to solve the sonic boom issue when he saw a kingfisher dive into the water from a high elevation without even making a splash. He was also aware that owl feathers have the unique ability to absorb sound so an owl can dive quietly on its prey.

Nakatsu and his fellow engineers took the examples that birds offered and built the front of their trains with the equivalent of a kingfisher bill. They also installed a quieter pantograph design based on owl’s wings. (The pantograph is the device mounted on top of an electric train to collect the power from an overhead cable.) in 1997, trains using those designs went into service, and the tunnel problem and noise issue were resolved.

It is called biomimicry when human designers copy something they see in nature to solve a technical problem. There are many examples of biomimicry from velcro to binding straps. God thought of it first, and humans have merely learned to copy God’s design. That’s how biomimicry solves a high-speed train problem.

Why Do Birds Fly North in Spring?

We all understand why birds of the Northern Hemisphere fly south in the fall. When the temperatures drop in Michigan, and the lakes are covered with ice, most birds have found a warmer place in the south. Michigan has many so-called “snowbirds” in the human population who leave us in November to go to Florida’s sunny shores. They come back in the spring to enjoy Michigan summers and because they have family here. The question is, why do birds fly north in spring? Couldn’t they save a lot of trouble by just staying in the south all year?

The answer to that question is food. The fact is that tropical areas simply don’t have enough insects to provide the protein that birds need to feed their chicks. When birds are in the south, they survive by eating berries, fruits, and nectar. None of those foods provide much protein. The time when birds return to the north coincides with the explosion of insects in the spring. They can enjoy less competition and longer days while dining on insects in the north.

The question remains as to how the birds know this? How do they know that they can benefit by traveling hundreds or thousands of miles in the spring? Why do the birds have the urge to fly north at the time that benefits them as well as the ecological systems they help to support? In other words, why do birds fly north in spring? The answer is that it’s built into their genes.

God’s view of Earth and the systems that make it work is far greater than ours. We are beginning to understand how many things, such as bird migration, must happen for the system of life to exist. It also speaks to us about how important it is that we take care of what God has given us.

Mesozoic Era Small Animals

What most people know about the dinosaurs is what they have seen in a movie or a museum. The emphasis is always on the massive size of these ancient animals. Those of us with a background in paleontology are more interested in the ecosystem in which they lived. The Mesozoic era was a time when the Earth was very different from what it is today. It appears that the oxygen content of the atmosphere was higher, and the temperature was much warmer. The plants and animals living at that time enjoyed a balanced ecosystem that left a legacy that has allowed us to live comfortably on this planet.

The natural resources humans have depended on for our entire history were produced during the Mesozoic era. These include coal, oil, and a wide variety of soils that allow our modern plants to exist. From a biblical standpoint, this was a part of Genesis 1:1 when God prepared the Earth for what was to follow. For more on this, see “God’s Revelation in His Rocks and His Word” on our doesgodexist.org website. (You can purchase printed copies HERE.)

What many people don’t realize is that while the giant dinosaurs were an essential part of the Mesozoic era ecosystem, small creatures were of equal importance. Insects were a significant part of the system, and fossil remains of all kinds of arthropods are abundant in the fossil record. As we all know, insects can reproduce in destructive numbers. Just as there were meat-eating dinosaurs to keep the plant-eaters from destroying all the vegetation, there were insect-eaters to control the insect populations. We have insect swarms like the locusts that are causing massive problems in Africa today because humans are removing the natural controllers of insect populations.

The recent discovery of a creature named Oculudentavis khaungraae has shown us a dinosaur the size of a bee hummingbird, the smallest known modern bird. This dinosaur’s skull was half an inch from front to back, and it had a mouth full of teeth. It was ideally suited for eating insects of all kinds and sizes and was undoubtedly a vital part of the ecosystem during the Mesozoic era of the dinosaurs. God has always used one existence to prepare for another, and the preparation of the early Earth for humans was a long and highly complex process.

Our existence on Earth is also a preparation for a far better one. Continuing to study God’s creation and His Word helps us prepare for that time when we will exist outside of space-time. Read about it in Revelation 22:1–5.

Chimpanzees and Humans

Books and articles have been published indicating that chimpanzees and humans share about 98.7% of the same genes. So some have suggested that chimpanzees should be considered 98.7% human and have all the rights that humans enjoy. There have been lawsuits to remove chimps from zoos or restrictive areas so they can express their “humanness.”

Objective observers who study chimp behavior in detail do not see chimps as human. The Bible makes it clear that only humans are created in the image of God. Being in God’s image leads to attributes that are unique to humans. Those include not only creative ability such as in art and music, but they also include the way we treat one another. In Galatians 3:28, Paul makes it clear that as Christians, there is no distinction between one human and another. Paul specifically includes “no male nor female” in his list of who are equals. The whole notion of marriage (Genesis 2:24) and the role of women (Proverbs 31:10-31) esteem and protects women.

Chimpanzees and humans are not alike. In his book The Human Swarm, Dr. Mark Moffett describes the real life of female chimpanzees. When female chimps reach sexual maturity, they leave their group never to return. Female chimps are beaten up or ignored by males except when they are in heat, and then sex is forced upon them. Female chimps do not befriend each other. They give birth in a private, hidden place to avoid having their babies killed by other females. Male chimps have no role in parenting or protecting the mother and baby.

There is an adage said in jest that we often hear in the break room at the graduate center, “Make sure your data conforms to your conclusions.” It is easy for us to interpret animal behavior as human-like, especially comparing chimpanzees and humans. But we must recognize human uniqueness. We have heard the horror story of a pet chimp turning on and seriously injuring a human. You can remove the chimp from its fellow animals, but you cannot remove the animal behavior from the chimp. We are the only beings created in God’s image.

Amazing Spring Timing

One of the things you hear people in our part of Michigan say is, “If you don’t like our weather, hang on for a few minutes, and it will change.” We have had a strange winter season. We had brutal temperatures, wind, and snow in early December, leading all of us to think it was going to be a terrible winter. As we got near the holidays, the weather became unseasonably warm. We waited anxiously for another blizzard like the ones we usually have after a warm spell in winter. It never happened. Now we see the amazing spring timing.

It was so warm in the winter that I worried about the glad bulbs I had dug up. I put them in buckets covered with moist newspaper and stored them in the garage for spring replanting. I was afraid they would leaf-out responding to temperature, but they seemed to be okay and had not budded out at all. The weather did turn cold, but not the sub-zero stuff we usually have. Now we are in mid-April and, even though it snowed two days ago (and is snowing again today), winter is essentially over, and I used my snowblower only once.

So now I just got the glad bulbs out of the bucket in the garage. They have been in an insulated, dark garage, covered with a foot of newspapers since I dug them up in October. Every single bulb has a green shoot coming out. They are ready to be planted. How did they know it was time? The temperature in the garage didn’t change. No sunlight got into the bucket.

I have always assumed that my daffodils, which are blooming like crazy, used the presence of direct sunlight and perhaps temperature to know when to come up and prepare to boom. The glads had none of those indicators available to them. I am not suggesting that the amazing spring timing is some kind of mystic intelligence that tells the glads it is time to go. Whether it is ultraviolet light or infrared that signals the glads, it is a highly well-designed system.

Amazing spring timing is fascinating. The hummingbirds seem to know when to come north. The sandhill cranes are circling overhead as they fly ahead of the weather systems that might otherwise threaten them. The baby deer are around in such numbers that no amount of predation threatens to wipe out the deer population. That is thanks to the synchronized births that seem to take place in almost all wild ungulates.

When God decided to challenge Job, He used the things that show design wisdom in His creation to convict Job of his ignorance. Job 38:39- 41:34 finds God challenging Job to look around and see God’s wisdom and power at work. There is no better time to see that than in the amazing spring timing. Let us all step away from the ills of humanity and look at what God has done.

Elephant Wakes and Anthropomorphism

One of the main sticking points for those who say that we are just highly evolved animals is the capacity of humans to display spiritual characteristics. Humans show creativity in our ability to create art and music, to feel guilt, to be sympathetic, to have a concept of self, and to worship. Those who suggest we are just animals with big brains and no unique qualities have tried for over 100 years to find examples of “human behavior” in the animal kingdom. Some of those attempts have been front-page stories such as the reports of Koko, the gorilla. The trainer claimed that Koko created works of art and adopted a cat as a pet, but the bias of Koko’s trainer turned out to be the cause of the behavior. Most researchers admit that there was a great deal of anthropomorphism involved in the stories about Koko, and the same goes for elephant wakes.

Anthropomorphism is the attribution of human characteristics or behavior to an animal. Recently the Washington Post and The Week have published articles about elephants grieving and holding wakes or “religious services” when one of their kind dies. As you read the reports, you see strong suggestions that the reporters are engaging in anthropomorphism to support their claims of elephant wakes.

One report tells of seeing elephants touching corpses with their trunks and trying to lift them. It said they were “performing dominance behaviors typically used to protect sought after resources such as plentiful fruit trees or shady groves.” The reports also tell of members of five different elephant families interacting with a corpse for three weeks. There is also mention of a ten-year-old elephant walking away from her mother’s body with liquid streaming from her temporal glands indicating “great stress.” To suggest that these behaviors are religious ceremonies or elephant wakes seems to be the least likely explanation.

Elephants are herd animals. The matriarch is the leader of the herd, and when that leader dies, a power struggle takes place among the other females. This competition involves great stress, but it is a long way from a religious service. There is no evidence of elephants comprehending death. Some try to lift the corpse to its feet, demonstrating a lack of understanding of death. No elephant has attempted a burial, memorial, or preservation.

Humans are created in the image of God. We not only grieve, but we engage in behavior that indicates a belief that the departed is in a better existence. We honor our dead, and we continue to honor their memory. This is a spiritual awareness that is unique to humans. The value of human life cannot be denigrated by trying to find animal behavior with the same cause and effect.

Doormaker Ants and Sealed Doorways

Ant behavior is a remarkable teacher. It teaches us God’s wisdom shown in all of His creatures, even down to the smallest and weakest. We see that wisdom in doormaker ants and sealed doorways.

The Bible refers to ants as models that humans would do well to imitate. In Proverbs 6:6-8 and 30:25, we read, “Go to the ant, consider its ways and be wise. It has no commander. No overseer or ruler, yet it stores its provisions in summer and gathers its food at harvest… Ants are creatures of little strength, yet they store up their food in the summer.”

We have mentioned before that various kinds of ants are programmed genetically to do things that they don’t think out but which show thinking and care. The species Stenamma alas is another example of a behavior that speaks of God’s design. These doormaker ants and sealed doorways show wisdom of design.

These ants build their colony so that the entrance is surrounded by hard material. The entrance is circular, and one ant is posted there with a nearby pebble that has been carefully chosen to fit the entrance exactly. The pebble is the same color and texture as the surroundings. When an enemy approaches, the guard ant rolls the pebble into the opening. The fit is so tight that enemies cannot dislodge it even if they find the opening. You can see why the scientists who study these ants call them doormaker ants.

This reminds us of the tombs of the Egyptian kings and people of Jesus day who made or selected large stones to carefully fit the entrance to their places of burial. Jesus was buried in such a tomb. Rolling away the stone from the entrance to the tomb of Jesus was not a simple task. (See Matthew 28:2.) It involved a violent earthquake and an angel. Most importantly, it involved the power of God over death. Unlike doormaker ants and sealed doorways, the stone was not moved to let Jesus out but to let others in to see that his body was gone.

What Are Viruses and What Is their Purpose?

It is self-evident that we are all impacted by something called a “virus.” What are viruses, and what is their purpose?

The first clue about viruses was in 1898 when scientists discovered that the cause of foot and mouth disease in livestock was something smaller than any bacteria. Because viruses are about 100 times smaller than bacteria, they could not be detected until electron microscopes were developed in 1931. Since viruses were too small to be filtered out, scientists initially thought they were liquids. They were given the name “virus” which comes from the Latin word for poison.

Later, scientists discovered that a virus is a protein (DNA or RNA) molecule enclosed in a capsid covered by a protective layer of fat, or lipids. The virus in and of itself is inert and unable to reproduce. So what is their purpose? When they come in contact with living cells, they insert their genetic material into the host, so the cell now produces viral protein. This may produce harmful and life-threatening results. Among the illnesses generated by viruses are the common cold, influenza, smallpox, chickenpox, herpes, shingles, AIDS, polio, rabies, Ebola, and others.

If the protein is beneficial, the virus can produce a useful evolutionary change. In that way, viruses are tools to create new genetic products. In today’s world of genetic engineering, the process is called transduction. We have pointed out before that many times good things come from evolutionary change. God designed living things with the ability to change and adapt. Scientists use viruses as tools to affect desired genetic changes in agricultural products to produce high protein corn, for example. Some viruses attack bacteria, and they are called bacteriophages. As bacteria have developed resistance to antibiotics, scientists are interested in using bacteriophages as a defense against harmful bacteria.

If they are not living things, then what are viruses? They are sometimes called “organisms on the edge of life.” They are not fully living on their own, but they possess some characteristics of living things. Viruses are very fragile because the only thing protecting them is a thin layer of fat, known as lipids. If the fat is dissolved, the protein molecule disperses and breaks down on its own. That is why any soap or detergent will destroy a virus, and why washing your hands with soap and warm water is essential. Heat melts fat, so water above 25 degrees Celsius (77 degrees F) for washing clothes, dishes, or hands will destroy viruses. Any solution which is more than 60% alcohol will dissolve fat and destroy the virus, as will bleach in a 1 to 5 ratio to water. Antibiotics or bactericides do not affect a virus because they only work on living tissue. Antibiotics cannot kill what is not alive.

The problem with viruses is that when they are transferred from animals into humans, or even different animals, they can be destructive. Scientists believe that the current coronavirus (SARS-CoV-2) is active in bats where it causes no problems. When the virus jumped into humans, the result was destructive.

Then, what is their purpose? Viruses can be useful tools in their proper place. They are part of the way life continues to exist on a changing Earth. Mismanagement of animals and food can cause a virus to become an enemy of humans. We have a repeat of the Frankenstein phenomenon when a potentially useful concept turns into a monster because of misuse.
